CATDOLL : CATDOLL: How to improve the efficiency of pig farming?

1. How to improve the efficiency of pig farming?

Answer: In the current management and breeding of many pig farms, it is believed that the development of contemporary pig farming is becoming more and more difficult and the risks are increasing, such as high-risk epidemics, unstable market changes, etc. So let us see how to improve the efficiency of pig farming.

1. Animal Nutrition and Welfare

At present, most large-scale pig farms use positioning pens, farrowing raised beds and other feeding methods for the purpose of intensification and scale. This occupies a small area and is conducive to saving labor. However, in the long run, it is not conducive to the production of breeding pigs, shortening the production period of breeding pigs and increasing the overall cost. Under normal circumstances, a sow can produce for 8 to 10 years, but nowadays most of them are between 3 and 5 years. In view of this situation, the exercise of the breeding pig group can be appropriately increased. Pig farms with conditions can add 1 to 2 kg/day of green feed to enhance nutrition, such as Dingmu'an, Ti Zhuangsu and other vitamins and trace elements: the positioning pen can be changed to a large pen for exercise (enter the exercise pen after 30 days of pregnancy to prevent fighting)

2. Relieve immunosuppression

Nowadays, epidemics are becoming more and more complicated. Problems arise mainly due to immunosuppression, mixed infection and low cure rate. In addition, feed contamination and the negative effects of some antibiotics (sulfonamides, fluphenazine, dimethoate, chloramphenicol, and oxytetracycline all cause immunosuppression) have a greater impact on immunosuppression. This has a lot to do with our usual medication and health care habits.

3. Antibiotics

Health care is based on scientific immunization procedures and supplements them. In addition to synthetic chemical antibacterial drugs, antibiotics are generally produced by fermentation and are important partners of humans. The abuse of antibiotics and hormones has an inhibitory effect on the innate immunity and growth and development of animals, and pathogens continue to mutate and have strong drug resistance. In particular, the frequent use of high-priced new veterinary drugs has led to epidemics that are incurable. Some pig farms have used all methods after the disease occurs, until all the pigs that should die have died, and the disease is considered cured. I am not opposed to the use of antibiotics, but they must be used scientifically, combined with biosafety and health care based on the actual situation of the farm, try to use low-priced veterinary drugs, and strictly add them according to the preventive amount. The time of medication should be different for different pig groups. It is generally recommended to use it once every 30 to 60 days, with a cycle of 5 to 7 days, and use medium and high-end veterinary drugs for treatment.

IV. Application of Probiotics

Microecological preparations include probiotics, enzyme preparations, oligosaccharides, bacteriocins and other products. Biological additives will develop in the direction of complex, special and specific types, with outstanding functions and good effects: Microecology also has the function of improving the body's immunity and changing the intestinal absorption function (small peptides, lactobacillus), increasing growth rate and reducing feed-to-meat ratio. Sows are the most laborious production function. They are constantly pregnant and giving birth under high reproduction frequency and fixed living space, and they are also injected with quite a lot of vaccines. Therefore, their physical constitution and health directly affect production and piglet health. It is even more important to use microecological preparations in the sow stage. Piglets will complete 90% of the immunization injections before 30Kg, which is also a critical period of physiological development (such as Dingzai'an: synbiotics, etc.), so the microecological health of piglets is also very important.

Hardware conditions are the foundation for raising pigs well and the premise for ensuring the regulation of the pigs' living environment. For new pig farms, scientific planning must be carried out to improve the level: for existing pig farms, improvements should be made if possible, and if not, manual management should be strengthened to maintain appropriate density and a good sanitary environment, provide good lighting and ventilation, and provide a good microenvironment: temperature, humidity and sanitary management are especially key. In short, raising pigs is more important than prevention, and prevention is more important than treatment. The combination of raising, prevention and treatment can improve the comprehensive benefits of breeding.

2. How to improve the efficiency of dairy cattle farming?

As the quality of life of the people continues to improve, the demand for milk is also increasing. I have the following opinions on how dairy farmers can improve their farming efficiency:

1. Improve milk quality and prevent and treat dairy cow diseases

In dairy cow breeding, limb diseases, uterine diseases and mastitis are the most likely to occur. These are common diseases that seriously affect the lactation of dairy cows and are extremely harmful. Therefore, in the process of dairy cow breeding, a comprehensive prevention and control method combining prevention with feeding management should be adopted to improve its breeding efficiency. By strengthening the disinfection of the cowshed environment, strictly implementing the correct milking operation procedures, and regularly conducting disease screening, problems can be discovered and solved in a timely manner.

2. Breeding high-yield dairy cows

An important problem in my country's early dairy farming was low milk production and poor milk quality. How to eliminate low-yield dairy cows and introduce and cultivate high-yield dairy cows that are suitable for my country's farming is an important issue. In the early days, my country spent a high price to introduce high-yield dairy cows from foreign countries. Their milk production was several times that of Chinese dairy cows. Through breeding with local dairy cows in my country, my country gradually cultivated a group of high-yield dairy cows, but their number has not been expanded on a large scale. Therefore, choosing high-yield dairy cows is a necessary choice for farmers to improve their efficiency.

3. Establish a risk-benefit sharing mechanism between dairy farming enterprises and milk processing enterprises

Nowadays, many farmers in my country choose to share risks and benefits with corresponding processing companies. This model can prevent the problem of farmers' milk not being sold and the price not being high when there is excess milk production capacity, and can effectively avoid the risks brought by market uncertainties. At the same time, companies will also expand their milk sales channels and increase demand for milk for their own interests. Dairy farmers can expand the scale of breeding and increase breeding benefits in a relatively safe situation.

Finally, we welcome everyone with other insights to discuss below!

3. How to improve the economic benefits of wild boar farming?

Answer: When raising wild boars in the mountains, you must first choose good breeds, which generally refers to pig breeds with good quality, fast growth, high stress resistance, stable traits, and the ability to adapt well to the natural conditions of a certain area and suitable for large-scale breeding. You need to determine the breed based on your own breeding purpose.

Selection of wild boars The appearance of wild boars for breeding should be gray-black or brown-red, with coarse and sparse hair, small ears, long and pointed mouth, small head and abdomen, thin and high feet, straight back without concave, and sharp teeth. At the same time, it is required that the sexual characteristics are obvious, the forequarters are deep and wide, the sexual function is vigorous, and the testicles are well developed; wild boars over 18 months old are tolerant of rough feed, eat quickly, eat a large amount, and are not picky eaters. Such wild boars have strong breeding performance. Wild boars were originally wild animals, and their main food is leaves and weeds. 60%~70% of the feed for artificial breeding should be green feed such as grass and vegetables.

Some farmers feed wild boars with complete feed, and do not limit the amount of feed in the early growth period. The nutritional level is too high, which makes the wild boars too fat, making it difficult for them to climb or mate normally. Therefore, wild boars should be properly restricted, mainly green feed, and exercise should be strengthened. Good management of wild boar breeding is the key to improving the breeding rate. Attach importance to breeding work. Wild boar dens are divided into inner dens and outer dens. The inner den is a place for "wild boars" to eat and sleep, with an area of ​​about 3.5 meters long and 2.5 meters wide; the outer den is a place for exercise, sunbathing and drinking water. A drinking trough is set up, with an area of ​​1.5 times that of the inner den. The inner and outer dens are mostly paved with cement mortar, but not too smooth, to keep the pens dry and clean. The difference between the "wild boar" and the domestic pig pens is that a passage must be built 1.2 meters away from the outer den to allow the breeding boar to enter any sows in estrus for breeding, and then return to the original room for breeding. 2. Feed formula: 20% corn flour, 33% wheat bran, 8-10% bean dregs or a little soybean Feeding technology Panax notoginseng sugar 22%, bone meal 0.5%, amino acid (per head per day) 15-40g iodized salt 0.5kg, green feed 15% 3. Disease prevention and control: ① Prevention and control of swine fever: Prevention and control of anti-swine fever disease: Anti-swine fever serum is injected intramuscularly 5ml each time, twice a day, for 3-4 consecutive days. A large dose (50 heads) of swine fever immune attenuated vaccine can also be used for subcutaneous intramuscular injection once. ② Prevention and control of swine pleuropneumonia: first inject penicillin 1.8 million × 2 intramuscularly (weight over 75 kg), then inject ofloxacin 5 ml × 2, twice a day, for three consecutive days, the effect is very good, ③ Prevention and control of swine erysipelas: This disease is also called "fighting mark". The treatment method can be deep intramuscular injection of 40,000 units of penicillin per kilogram of body weight, twice a day, for 3 to 5 consecutive days, and wipe the pig body with strong soapy water, rub it into a state where soap bubbles cover the pig body, which has a miraculous effect. Fattening method for special wild boars The staged fattening method of special wild boars not only saves a lot of concentrated feed, but also makes full use of green roughage to make up for the defects of slow growth and long fattening period of special wild boars. It reduces production costs and improves the quality of wild boar meat. It is a key technology for special wild boar breeding to obtain high benefits. If this technology is not mastered well, it may cause the decline of special wild boar meat quality and increase production costs, thus putting special wild boar breeding into a dilemma. On the one hand, there is no difference between the special wild boar meat produced and the ordinary domestic pork; on the other hand, the production cost of special wild boars is much higher than that of ordinary domestic pigs and they are eliminated by the market. The linear fattening method is also called the consistent fattening method. This fattening method is to supply high-energy, high-protein complete compound feed from small pigs to large pigs. It is characterized by fast growth rate and high feed utilization rate. It is suitable for fattening lean domestic pigs, but not for fattening special wild boars. Now some farms use compound feed to feed special wild boars. Although it increases the growth rate, it reduces the quality of wild boar meat and increases production costs. As a product with game characteristics, special wild boar meat must maintain the unique flavor of wild boar meat to attract consumers. If special wild boars are raised as domestic pigs, they will inevitably lose their market competitiveness.

4. How to improve the efficiency of laying hen farming from the perspective of reproductive science?

You can install electric lighting in the breeding shed to lay two eggs a day.

5. How to improve the economic benefits of breeding greenhouses?

Using greenhouses to grow off-season vegetables is an important project for our farmers to increase their income. Although the investment is much larger than that of open fields, if the planting is good, the income is far greater than that of open fields. However, if the management is not good, the loss will be greater. How to plant and manage to improve the economic benefits of greenhouses?

First, because greenhouses have the advantage of heat preservation, when choosing vegetable varieties to plant, priority should be given to vegetables that cannot be planted in winter and vegetables that have relatively harsh temperature requirements. At the same time, they are popular vegetables in the market, and they have certain cold resistance and stress resistance in the selection of vegetable varieties. They have high yields, good quality and good economic benefits in greenhouses. At the same time, they are vegetable varieties that cannot be preserved in the open field until they are sold in winter. Off-season planting will achieve good results. For example, vegetables such as cucumbers, eggplants, Chinese toon sprouts, peppers, and some melons.

Second, in order to make full use of the effective space in the greenhouse. Use three-dimensional planting to increase the multiple cropping index. Generally, winter greenhouses mainly supply from New Year's Day and Spring Festival to around May Day of the following year. For the vegetables planted, plant them reasonably densely. For example, cucumbers should be cold-resistant varieties. Use main rows and secondary rows for planting. Increase to about 6,500 plants per mu. When the tenth leaf appears on the secondary row cucumber, remove the top. Leave about 12 leaves on each plant. Each plant has 3-4 cucumbers. When these three or four cucumbers are finished, the secondary row cucumber vines can be pulled out. This method can increase the early yield of cucumbers by about 30%.

3. Reduce the humidity in the greenhouse, reduce the occurrence of pests and diseases, and increase the ground temperature in the greenhouse. Low temperature and high humidity in the greenhouse can easily cause slow growth of seedlings and low disease resistance. Generally, double film covering is adopted. Before planting the seedlings, 3,000 kg of fully decomposed organic fertilizer is applied per mu, and the application of nitrogen fertilizer is appropriately reduced to prevent excessive ammonia in the greenhouse in the future, which will cause harm to the vegetables. After plowing, the fertilizer is mixed with the soil. Cover the whole greenhouse with ground film. If conditions permit, drip irrigation bags can be laid, which can significantly reduce the humidity in the greenhouse and increase the ground temperature in the greenhouse. When preparing the land, add 5 grams of carbendazim per square meter to disinfect the soil. Reduce the occurrence of diseases in the future. For some vegetables, an additional small arch shed can be added, which is more conducive to increasing the ground temperature.

Fourth, no one can accurately control the changes in the market. When choosing vegetable varieties, develop more high-end vegetables and manage vegetables carefully. For ordinary off-season vegetables, try to target market gaps. For the same kind of vegetables, if the weather is good and the temperature is relatively high in winter, the yield of the vegetables will be high and the price will be low. On the contrary, the price will be high and the yield will be low. Therefore, in bad weather, what matters is technology.

5. If you plant cucumbers, you usually use black seed pumpkin grafted seedlings for planting. Black seed pumpkin has relatively good disease resistance and can cope well with the occurrence of greenhouse continuous cropping disease. Generally, in continuous cropping land, the yield of cucumbers is increased by more than 20% compared with those without grafted seedlings. In order to increase the cucumber fruit setting rate, you can spray the leaves with a concentration of 0.2% ethephon solution when the cucumber seedlings are in the second leaf stage, which is conducive to the differentiation of female flowers of cucumbers.

Sixth, apply gas fertilizer. Since the greenhouse is relatively tightly closed and the air flow is relatively poor, the carbon dioxide gas used to make nutrients is obviously not as much as that in the open field. In order to increase the yield of vegetables in the greenhouse, carbon dioxide gas can be added to the greenhouse vegetables. The method of adding gas is generally to use sulfuric acid and ammonium bicarbonate to react chemically at around nine o'clock on a sunny day. When diluting concentrated sulfuric acid, first prepare three parts of water by volume, place the water in an open plastic bucket, and pour one part of concentrated sulfuric acid along the glass rod. Slowly pour it into the water. Do not pour the water directly into the concentrated sulfuric acid. 30-40 plastic buckets of the same type are required per acre. About 50-100 grams of ammonium bicarbonate are placed in each bucket each time. Carbon dioxide gas that can be used by vegetables is produced. It is generally best used during the peak fruit period. Close it for a period of time and ventilate it in time. If a reflective curtain is hung on the back wall of the solar greenhouse, scattered light can be increased, which is conducive to the production of light substances.

7. Selection of greenhouse film. The solar greenhouse generally uses polyvinyl chloride drip-free film. The drip-free film can increase the permeability of light and reduce the obstruction of light caused by water droplets condensation. It can increase the temperature of the greenhouse and reduce the humidity in the greenhouse.

6. What are the benefits of ostrich farming?

This is a new breeding project in my country in recent years. According to the current development, it is still feasible. After deducting various expenses, the profit generated is only about 300 yuan per day.

7. What are the benefits of raising wild rabbits?

The average weight of a hare is about 2.5 kg, the largest is about 3.5 kg, and 4 kg hares are rare. The price varies from place to place. In mountainous rural areas where there are many hares, you can buy one for 30 yuan, while in big cities, a hare costs about 80 to 100 yuan.

8. How can we improve the production efficiency of the breeding industry?

Grasping "increasing income and reducing expenditure" is the key to effectively improving the economic benefits of farmers. Specifically, the following points should be grasped:

1. Raise animals scientifically, select superior breeds, use reasonable and practical enclosures and feeding methods, master feeding techniques, and learn management;

2. Strengthen feeding management and do routine work well, such as regular and quantitative feeding, good pen hygiene, regular disinfection, routine immunization and deworming, etc.;

3. Market the animals at the right time and understand the market situation, etc.

9. Fish farming technology?

1.

Stocking time selection: Fish should be released on sunny days when the temperature is not too low. Generally, the temperature should be between 2℃ and 5℃. At this stage, the fish scales are tight and the activity is small. It is not easy to injure the fish during fishing, transportation and stocking operations, which can reduce the morbidity and mortality of fish. It is easy to frostbite the fish on rainy days with low temperature or snowy, frozen and windy weather; when the temperature is too high, the fish scales are loose and the activity is large, which is easy to injure the fish during operation.

2.

Stocking of fish: Before stocking the fish, check whether the drugs have lost their effectiveness after pond cleaning. In early spring, the water temperature is low and the toxicity disappears slowly. Water should be taken in advance and test fish should be released. According to the stocking plan, individual size, density, and matching species and specifications, the fish that can be released at one time should not be released in batches, so that the fish can adapt to the environment, start eating early, and promote growth. At the same time, [Gold Iodine] should be used for drug disinfection when stocking fish.

3.

Feeding at the right time When the water temperature rises to 810℃, fish begin to eat, and the amount of food intake gradually increases with the increase of water temperature, so they should be fed in time. Feed once a day or every other day, and choose to feed at noon on a sunny day; as the water temperature continues to rise, the number of feedings can be increased to twice, that is, feeding once in the morning and once in the afternoon. Feeding should adhere to the principle of four determinations (timing, quality, positioning, and quantity), and the specific daily feeding amount should be flexibly controlled according to the weather, water temperature, and the feeding situation of fish. For grass carp weighing more than 1 jin, it is recommended to feed Da Beinong high-grade expanded feed 8103 in the early stage of feeding; for small grass carp mode, it is recommended to feed Da Beinong microecological juvenile fish special feed [Intestinal Liver Health], and the feeding rate is controlled at about 0.5%1%. This product is rich in nutrients and probiotics, which can quickly repair the fish intestines, restore the physique, and improve immunity.

10. How to improve the efficiency of running a school?

1. Prepare lessons thoroughly outside of class

Lesson preparation is an extremely important part of teaching work. When the teacher's level, textbook content and student foundation are already determined, lesson preparation is the prerequisite for whether the teacher can teach well. Whether the teacher can prepare lessons seriously and be good at preparing lessons is also the main link in whether the teaching level can be improved quickly. No matter how the curriculum reform is changed, studying the curriculum standards and mastering the textbooks are the basic skills of teachers forever. If the teacher himself does not have a thorough understanding of the curriculum standards and textbooks, it is difficult to effectively guide students.

With the implementation of quality education, the main body of the classroom has changed from "the main body of teaching" to "the main body of learning", "teaching is to stop teaching". In other words, students who used to stand on the edge of the classroom should stand in the center of the classroom to dominate the classroom. Teachers should really make the classroom "all for students" and truly make the classroom a classroom for students. Therefore, I believe that lesson preparation should include two aspects: one is to prepare teaching materials; the other is to prepare students.

1. Prepare teaching materials

The most fearful thing when driving is that you are not familiar with the road, and the most fearful thing when teaching is that you are not familiar with the teaching materials. To let students have a glass of water, you must first have a bucket of water. "Ask where the canal is so clear, because there is a source of living water." I think that as a teacher, reading a lot of books, striving to improve one's own theoretical level and knowledge cultivation, and using advanced teaching theories to guide one's own teaching, this is the channel of our thinking, the clear living water. Before class, teachers must first thoroughly understand the teaching materials. In the process of preparing lessons, teachers should carefully study the curriculum standards, read the teaching materials, study and understand the writing intentions, ideological content, knowledge base and key points of basic training of the teaching materials, so as to determine the key points and difficulties in teaching, so as to design scientific teaching methods and make necessary preparations for achieving teaching goals. Only when the classroom teaching objectives are clear can we effectively overcome the arbitrariness and blindness in teaching and strengthen the pertinence of teaching; clarifying what the focus of teaching is, we can avoid grabbing eyebrows and beards at once, being detailed when it is detailed, and being brief when it is brief, and distinguishing the primary and secondary; grasping the difficulties of the classroom, the form of teaching design, and the way of dealing with problems will not be single. Only when teachers study the teaching materials in depth and carefully design classroom teaching can they achieve good teaching results.

2. Prepare students

In addition to thoroughly understanding the teaching materials, teachers must also thoroughly understand the students before class preparation. The illiterate in the 21st century are not those who cannot read, but those who cannot learn. In quality education, students are the real masters of the classroom. Whether the lessons prepared by teachers can be accepted by students is a question that needs to be tested in practice. Therefore, teachers must prepare students while preparing teaching materials.

1. First of all, we must understand the actual situation of students, target them and teach them in accordance with their aptitude. The differences in students' knowledge levels and receptive abilities are a reality we must accept. How to understand and deal with this problem is also the key to our successful classroom.

2. Secondly, we must master the art of asking questions and give students the pleasure of success. In the learning process, if students have a successful emotional experience repeatedly, they will have a sense of pleasure in learning. Therefore, teachers should try to give students the satisfaction of success in teaching practice. When asking questions in class, the questions should not be too difficult or too easy. If the questions are too difficult, students will have no idea where to start and it will be out of reach. In the long run, students will easily lose confidence and interest, which will affect the efficiency of the class. If the questions are too easy, students can answer them without thinking, which is not challenging. Even if they answer correctly, they will not feel successful, which will also affect the efficiency of the class. Therefore, when setting and asking questions, teachers should fully understand the actual learning situation of each student, let students of different levels answer questions of different difficulty, so that students of different levels can have a successful experience, thereby establishing confidence in learning and maintaining a strong interest. In addition, students may have a variety of answers to questions. Regardless of whether the students answer correctly or not, teachers should promptly affirm the students' unique way of thinking, and praise students who can answer questions correctly, so that students can experience the joy of teachers' appreciation. When students have a sense of success, they will have confidence and interest in themselves, and will study more proactively, actively and attentively, thereby improving classroom efficiency.

3. Finally, the teaching method should be intuitive and flexible. According to the physical and mental characteristics of students (especially junior high school students), such as short attention span, restlessness, and impatience, teachers should make full use of intuitive, flexible and diverse teaching methods in classroom teaching, so that students can master knowledge and receive education in a pleasant mood. In particular, multimedia courseware can provide real, vivid and touching materials, strongly attract students, improve classroom efficiency, and liven up the classroom atmosphere. It is a good way to improve classroom efficiency. Multimedia teaching brings intuitiveness and liveliness to classroom teaching. It makes the leading role of teachers and the main role of students complement each other. It greatly increases students' interest in learning, which is conducive to their mastery of teaching content. It is especially conducive to cultivating and improving students' abilities and improving their comprehensive quality, which also improves classroom efficiency.

2. Carefully study in class

In quality education, the main body of the classroom is students. Therefore, we should change the past teaching method of cramming, reduce teachers' teaching and speaking, and increase students' thinking and understanding. Teachers play a leading role in teaching. They should know the teaching objectives and key points of each class, where to inspire and guide, where to explain, and where to emphasize. Teachers should grasp the scale of "speaking" and must not speak about everything, ask everything, and sing a "single show". If students' time for reading, thinking, and practicing is squeezed out, the efficiency of classroom teaching will not be high. For a long time, an important reason for the low efficiency of classroom teaching is that teachers talk too much and students do too little. Teachers talk less, students read more, think more, and practice more, and give students the initiative of learning. This is also the most basic requirement of quality education. In the classroom, the greater role of teachers is "guiding" rather than "teaching". Students' "learning" is the starting point and end point of teaching. We should make a fuss about how students "learn" and focus on letting students "understand". Teachers should give students more time to "understand". As the saying goes, a teacher can only lead you to the door, but it is up to you to practice. In fact, a lot of knowledge is not taught, but understood. If teachers talk less, they should be precise and grasp what knowledge needs to be taught and what knowledge does not need to be taught. If teachers are flawless and talk a lot in class, they will lead students into a maze. Teachers should give students some time to "understand". However, teachers should grasp the time for students to "understand" and design the time for "understanding" according to the actual overall intelligence level of students. They cannot only ask one or two questions and let students "understand" all the time throughout the class. In this way, teachers will not only fail to complete the teaching tasks, but also fail to improve the efficiency of classroom teaching. Like my school (Changtai No. 2 Middle School), some of the excellent students were admitted to other good schools, and another part went to private schools. The overall intelligence level of the remaining students in school is medium and lower. In this actual situation, I think: First, students should be allowed to preview before class. Only if students prepare before class can they know the answers to questions asked by teachers in class. Only in this way can teachers complete teaching tasks and improve classroom efficiency in a short class. Second, the questions asked by teachers should not be too difficult. If they are too difficult, most students cannot answer them. Third, the students who ask questions should have different levels. For difficult questions, ask excellent students; for less difficult questions, ask average students; for easy questions, ask poor students. Teachers cannot always ask good students and ignore or pay little attention to poor students. In the process of education, teachers should devote all their love and enthusiasm to students and treat all education objects equally. When giving excellent students "icing on the cake", they must pay attention to "giving timely help" to middle students and temporarily poor students so that they can transform into excellent students. Teachers' expectations are an important factor affecting students' interest in learning. These methods allow students to experience happiness and devote themselves to learning with full enthusiasm. If students are interested in the knowledge they learn, they can concentrate, think actively, and take the initiative to discover and explore knowledge, thereby improving the quality and efficiency of classroom teaching. Fourth, teachers should also grasp the time of "understanding" according to the actual situation. If students cannot "understand" in a short period of time, teachers should inspire them from time to time, and not let time pass in vain. If students still cannot answer after the teacher's constant inspiration, I think that at this time, the teacher has to "teach" and let students "understand" in their spare time, otherwise, the teaching task cannot be completed. Teachers should grasp this point flexibly. Fifth, we should strive to create a "harmonious situation" and a "happy learning atmosphere". Psychological research shows that a good mood, mood, and positive emotions play an extremely important role in learning. Therefore, in actual teaching, teachers should strive to create a "harmonious situation" and "enjoyable learning atmosphere", use various humor, analogy and other rich language and multimedia and other modern teaching tools to stimulate students' interest, encourage students to actively explore with vigorous energy and positive attitude, so as to optimize classroom teaching, realize the transformation of students from "I have to learn" to "I want to learn", from "learning" to "learning", fundamentally reduce students' pressure and burden, and enable students to learn cognition, life, application and creation easily and happily. In this way, the efficiency of classroom teaching can also be improved.

In short, there is no fixed method for teaching, but the key is to find the right method. Classroom teaching is a creative labor, and creativity is the vitality of teaching activities. As long as it can stimulate students' interest in learning, improve students' enthusiasm for learning, help cultivate students' thinking ability, and facilitate the mastery and application of learned knowledge, it is a good teaching method. Our teachers choose to use appropriate teaching methods to teach, and students will be interested in learning, which will help improve learning efficiency and classroom efficiency. The above is just my shallow opinion on classroom teaching. In future teaching practice, I will continue to explore more scientific teaching methods that are in line with the actual situation of our school, so as to continuously improve the efficiency of classroom teaching. "The road is long and arduous, and I will search up and down."
