CATDOLL : CATDOLL: How to raise silkworms (How to raise silkworms to keep them alive)

1. What are the correct methods and techniques for raising silkworms?

1. Mulberry leaves should be picked, transported and stored properly. Try to pick leaves in the morning or evening, transport them as soon as they are picked, and pack them loosely for fast transportation. After the picked mulberry leaves are loosened, put them in the mulberry storage pool or mulberry storage room, and store them properly to prevent them from being blown away by the wind or piled up and heated and deteriorated, which will cause waste of mulberry leaves.

2. Prevent mulberry leaves from wilting. During the young silkworm stage, use a kang bed (room) and cover the mulberry leaves with plastic film to keep the temperature and moisture, so that the mulberry leaves remain fresh. During the adult silkworm stage, close the doors and windows appropriately after feeding the silkworms, and open the doors and windows for ventilation after the silkworms have eaten about 70% of the mulberry leaves, which can effectively prevent the mulberry leaves from wilting.

3. Ensure the temperature of the silkworm room. The suitable temperature for large and small silkworms is 24℃ and 25℃ respectively. Within the suitable temperature range, the silkworms have a strong appetite, which reduces the defective mulberry leaves and improves the leaf-silk conversion rate.

4. Promote less-return rearing and mulberry-strip rearing. Labor-saving silkworm rearing technologies such as flat three-dimensional rearing of small silkworms once a day, rearing of full-age silkworms twice, and rearing of large silkworms in mulberry strips not only improve the efficiency of silkworm rearing, but also help silkworms eat mulberry leaves, saving about 5% of mulberry leaves compared with ordinary rearing.

Summer and autumn silkworm breeding should pay attention to

1. Prevent pesticide poisoning. During the silkworm-raising season, do not spray organic pesticides such as dimethoate in the silkworm room and the fields near the mulberry fields, as the smell will cause poisoning to the silkworms; mulberry leaves should be fed to the silkworms only after they have been tested and confirmed to be non-toxic.

2. Mosquito-repellent incense or mosquito repellent or insecticide is prohibited in the silkworm room. If it is used in the house near the silkworm room, the doors and windows of the silkworm room should be closed to prevent the silkworms from being poisoned.

3. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the room and harming the silkworms, and "silkworm fly killing" emulsion should be added or sprayed on the silkworm bodies to kill the maggots.

2. What is the best way to raise silkworms?

1. Management of silkworm cages. Silkworms are usually raised in cages, which is convenient for management and growth. Considering the fragility of silkworms, first of all, the silkworm cages must be disinfected in place. It is best to expose them to the sun for a few days after disinfection to achieve the effect of natural disinfection. Secondly, do not choose materials with strong water absorption, as silkworms prefer a relatively dry environment. Secondly, the location of the silkworm cage should not be in a place with too bright light, as this is not conducive to the growth of silkworms.

2. Feeding and management. The mulberry leaves fed to silkworms in different time periods are also different, so special attention should be paid. In order to ensure the initial development, the mulberry leaves in the early stage must be relatively fresh and tender. Silkworms do not need water when feeding, and their water source all comes from mulberry leaves, so try to feed them fresh mulberry leaves each time, and drain the water from the leaves. The feeding time is generally from 7 am to about 10 pm, with 4 to 5 feedings in between. The mulberry leaves must cover the silkworms, which is conducive to eating. The thickness is generally about 3-4 layers of mulberry leaves.

3. Environmental management. Silkworms are sensitive to light and temperature. In the early stage, young silkworms should generally avoid exposure to light. In the presence of light, the hatching process is slow and the temperature should be controlled at around 25-30℃. In the early stage after hatching, the temperature should be kept at around 30-33℃. At this time, the control of light can be slightly loose, but continuous bright light should still be avoided as much as possible. In the middle and late stages, the temperature should be controlled at around 25℃. At this time, a bright environment can be maintained occasionally, but it should still be mainly dim.

4. Precautions. First of all, silkworms are very fragile. Once diarrhea occurs, it is a very serious problem for silkworms. They must be isolated in time to avoid further impact. Secondly, the feces should be cleaned. In order to avoid harm to the silkworms during cleaning, it is recommended not to clean too many times. Generally, cleaning is done when the silkworm feces accumulate too deep. Secondly, the remaining stems of mulberry leaves must be cleaned in time to avoid harming the silkworms. Finally, the environment for raising silkworms must be kept relatively ventilated to avoid being too stuffy.

3. Top ten tips for raising silkworms?

Silkworm breeding method

1. Do a good job in disinfection and disease prevention

Because the interval between silkworm breeding in summer is short, pathogens are fresh and large in quantity, and are easy to infect, we should pay attention to environmental sanitation and thoroughly disinfect the silkworm room and silkworm tools. You can spray disinfectant first, then clean and wash them. When spraying, pay attention to the dosage and spray all the surfaces. Strictly implement the "three disinfection principles" (that is, thoroughly disinfect before silkworm breeding, continue disinfection during silkworm breeding, and disinfect immediately after silkworm breeding), and carry out disinfection and disease prevention throughout the entire silkworm breeding process.

When harvesting leaves for summer silkworms, attention should be paid to the safe interval of pesticide application. Mulberry leaves from areas where pesticides are applied must be harvested and fed after the residual period has expired. Only after they are proven to be non-toxic can leaves be harvested for feeding. Summer silkworms should be protected from flies and rats to avoid losses.

2. Adjust the room temperature for silkworm rearing

According to the characteristics of summer climate, take corresponding measures to adjust and improve the silkworm breeding environment. In hot and humid weather, pay attention to ventilation, and cool down and moisturize when it is hot and dry. Plastic film can be used to cover the young silkworms, which can keep warm and moisturize, which is conducive to the healthy development of silkworms. In the adult silkworm period, choose a tall, spacious and well-ventilated house to prevent stuffiness. Plant trees and build a pergola around the silkworm house to reduce radiation.

3. Do a good job in mulberry leaf management

The quality of mulberry leaves is directly related to whether the summer silkworm harvest is good or not. We should strengthen the fertilization and pest control of mulberry trees to promote the growth of mulberry trees. During the young silkworm period (1 to 3 years old), it is key to pick the leaves that are ripe, with the color being pure green and soft to the touch as the standard. When collecting mulberry leaves for ants, you should choose mulberry leaves that are ripe and tender, and avoid using leaves that are not exposed to enough sunlight, old leaves, wilted leaves, diseased and insect-infested leaves, and mulberry leaves contaminated by pesticides. The leaves for summer silkworms should be picked in the morning before the dew dries or in the evening. Leaves must not be picked in the middle of the day (except on rainy days). The picked mulberry leaves should be picked and transported quickly to prevent the mulberry leaves from emitting moisture and withering. Pay special attention to not stacking mulberry leaves too high or too thick to prevent them from rotting.

4. Do a good job in feeding management

First, the transportation of silkworm eggs. When transporting silkworm eggs, do not pile them up or pile them up, and try to avoid contact with high temperatures. The transportation of silkworm eggs should be carried out in the morning and evening, and they should be spread out in time after being brought back to prevent accumulation and heating. When distributing silkworm eggs, try to do it in the morning and evening. Silkworm eggs should not come into contact with pesticides and all harmful gases to prevent silkworm poisoning.

Second, feed the young silkworms. Plastic film can be used to cover the silkworms. Silkworms grow and develop quickly, so the area of ​​silkworm seats should be expanded in advance to prevent them from being crowded and hungry. Disinfect the silkworm bodies and silkworm seats with fresh lime powder or 2% effective chlorine anti-stiffness powder every day. Add 500 times diluted silkworm disease sterilization spirit, Yijiling, and Kejunxing to feed the young silkworms when they wake up. Use 0.3% effective chlorine to soak or spray the leaves for disinfection, dehydrate, and dry them before feeding them.

Three-catch adult silkworm rearing. During the period, three sparse should be achieved: the silkworm racks in the silkworm room are sparsely connected, the silkworm foils on the silkworm racks are sparsely placed, and the silkworm heads in the silkworm foils are sparsely placed. This is conducive to ventilation, lowering the temperature, and ensuring that the silkworms are fully fed. During the adult silkworm period, especially during the hot and humid period, the silkworm litter should be removed frequently to keep the silkworm seats clean and dry. During the adult silkworm period, labor-saving silkworm rearing should be implemented. During the adult silkworm period, 300 times the liquid of fly-killing tablets should be sprayed on the silkworm bodies and 500 times the liquid should be added to the food to prevent maggots from harming them.

Fourth, cluster management. In order to reduce labor costs, it is advisable to adopt automated cluster technology. The specific method is: when the silkworms develop evenly and 5-10% of the silkworms are mature, use 4-6 pieces of Chuanto for each silkworm seed and mix 20-30 jin of mulberry leaves with cold boiled water (4-6 pieces with 1-1.5 jin of water), feed the silkworms at 10-12 pm, and no longer feed mulberry leaves. At 10-12 am the next day, sprinkle some straw or silk nets on the silkworm seat, and put plastic clusters or square clusters on the silkworm seat to let the mature silkworms automatically cluster and make cocoons. After clustering, strengthen the ventilation and dehumidification of the cluster room (use electric fans to dehumidify if conditions permit), so that the cluster room, cluster tools, and environment are dry, improve the yield and quality of silk cocoons, and ensure stable and high yields of summer silkworms.

4. How to raise silkworms to achieve high yield and good quality?

Planting mulberry trees to raise silkworms is an important skill of the working people. It has been practiced in ancient times and has been passed down to this day. At present, in many areas, farmers have achieved good returns through silkworm breeding. In the process of silkworm breeding, how to ensure quality and increase production is also a topic often discussed by farmers.

Do a good job of cooling and moisturizing

The most suitable temperature for raising silkworms is 26 degrees, and the difference between dryness and wetness is about 3 degrees. If the temperature of the breeding environment is too high and too dry, the silkworms' digestive ability will decrease, their metabolic function will be hindered, and their growth rate will be affected. It is necessary to cool down and moisturize to improve the breeding environment and create a good breeding site for the silkworms.

Cooling

Nowadays, the sites for raising silkworms are generally single-layer cement structures. In the hot summer, it is easy to absorb heat. If the silkworm room is facing east, the sunlight will shine directly in and the temperature will rise. A sunshade can be set up around the silkworm room to block strong light and ultraviolet rays, which will have a cooling effect.

During the silkworm rearing period, the temperature should be recorded. Generally, the temperature at noon is 3 to 4 degrees higher than that in the morning and evening. Therefore, at noon, turning on the fan for 20 minutes can expel the indoor heat, and the air exchange will achieve the effect of cooling. When turning on the fan, the wind force and time should be controlled. Too much airflow will have a counter-effect, accelerating the drying of mulberry leaves, and the silkworms will not be able to absorb nutrients after eating.

Moisturizing

Silkworms like to grow in an environment with relatively high humidity. Mastering the humidity requirements of silkworms at each stage of growth will help them to have a high yield when it comes time to harvest cocoons. When the humidity of the breeding environment is not up to standard in hot weather, water is the most effective substance to compensate for the humidity. Every day at noon or evening, you can sprinkle some water on the outer wall of the silkworm room to moisturize it physically.

In the cement-structured silkworm room, water can be stored in the drainage ditches on the roof or around the room. When the temperature reaches a certain level, water vapor is generated, which plays a role in cooling and moisturizing.

Provide high-quality mulberry leaves for silkworms to eat and strengthen their physique

Artificial silkworm rearing requires good and full feeding. Providing high-quality mulberry leaves is the guarantee of health. The quality of the leaves directly affects the growth of silkworms. Strengthen the cultivation and management of mulberry gardens to make mulberry leaves fresh and nutritious to meet the nutritional needs of silkworms.

The management of mulberry gardens is the key point. Different seasons will produce different insect pests. We should strengthen insect prevention in mulberry gardens, combine drugs with manual capture methods, and reduce the transmission of pathogens carried by mulberry leaves to silkworms. When using drugs to disinfect mulberry gardens, there should be a certain interval area to prevent silkworms from being accidentally injured.

According to the growth characteristics of silkworms at different stages, suitable mulberry leaves should be picked. Leaf quality is very important to the health of silkworms, especially for newly hatched silkworms. They should not eat old or withered leaves, but only fresh and tender leaves. If there are insect pests in the mulberry leaves, they can be disinfected with drugs and used to feed adult silkworms.

The harvesting, transportation and storage of mulberry leaves should be done well, and the leaves should be kept fresh as much as possible to prevent them from becoming moldy and deteriorating. Mulberry leaves should be picked in the morning or evening as they are easy to dry out if picked at noon. The harvested mulberry leaves should be placed in a mulberry storage room in a low temperature and humid environment to prevent them from withering.

Strengthen feeding management measures

1. During their development, silkworms have different requirements for the external environment. We must grasp these characteristics, provide the most favorable conditions for their development, and enable the silkworms to grow healthily.

2. Strictly follow the standards for inducing rapid hatching to cover the ants with black, and collect the ants at the appropriate time. The silkworms can be collected earlier in summer and autumn. If the hatching time is inconsistent, the ants should be collected in batches. It is best to use a net to prevent the ants and silkworms from being harmed.

3. The temperature and humidity requirements of young silkworms and adult silkworms are inconsistent. Many people may not know that young silkworms are more resistant to low humidity than adult silkworms, but young silkworms are weaker than adult silkworms to dryness and low humidity. Therefore, high temperature environment is not good for both adult and young silkworms. In summer, we must do a good job of cooling and moisturizing.

4. Newly hatched silkworms have the weakest resistance to adverse environments and pathogenic microorganisms, so during the feeding period, they must be carefully managed. The silkworms cannot be fed in groups, and the breeding grounds must be expanded in time to prevent the silkworm heads from being squeezed and injured. During the feeding period, cleaning work must be done well, and the sand must be removed gently to avoid injuring the silkworms and infecting them with bacteria.

Do a good job in disinfection of silkworms

The silkworm breeding room and feeding tools are contaminated with pathogens and need to be disinfected regularly. In the spring, before raising silkworms, the silkworm room should be cleaned and rinsed with clean water, and the tools and materials to be used should also be taken outdoors for disinfection.

In the middle of breeding, although the silkworm room and tools have been disinfected, pathogens will enter the silkworm room through other ways after breeding for a period of time. Therefore, the early disinfection work cannot guarantee that bacteria will not be infected again. Disinfection and sterilization work must be done well during the entire breeding period. Silkworm feces and excrement are the places with the most bacteria. If they are not removed in time, the bacteria will spread and cause diseases. Cleaning silkworm feces and excrement in time cannot be delayed.

During the silkworm rearing period, after the sand removal work is completed, the inside of the silkworm room should be sprayed with bleaching powder containing 1% effective chlorine for disinfection. The room where mulberry leaves are stored should be cleaned regularly and disinfected with bleaching powder containing 1% effective chlorine every two days.

After the cocoon harvesting is completed, if there are any rotten cocoons or dead bodies of diseased silkworms left, they must be gathered and sterilized outside to prevent the spread of pathogens. After the silkworm rearing period is over, the silkworm room and utensils must also be cleaned, dried, fumigated and sterilized, and the outdoor area must also be disinfected.

summary:

To achieve high yields in silkworm breeding, it is necessary to understand the environmental requirements of silkworms at each stage of growth, reasonably control the temperature and temperature, and provide silkworms with high-quality mulberry leaves to provide adequate nutritional supplements. During the breeding period, the silkworm room and utensils should be disinfected regularly to reduce the chance of disease. Scientific breeding can ensure quality and achieve high yields.

5. How to learn the complete set of techniques for raising silkworms?

1. To raise silkworms, you must first buy silkworm seeds, which are silkworm eggs. This product has the ability to hatch silkworms. Every spring, when the temperature remains around 20 degrees, silkworms will hatch from silkworms.

2. After the silkworms hatch, you need to pick mulberry leaves to feed them. The chewing ability of silkworms is not that strong, so you should choose relatively tender mulberry leaves. There should be no water or pesticides on the mulberry leaves.

3. Silkworms can be raised in paper boxes. If the scale is larger, they can be raised in special bamboo boxes, which must be breathable, hygienic and clean.

4. Raising silkworms has relatively high requirements for the environment. There must be no fumes, no mosquitoes, no mosquito coils, no spraying of pesticides, and no dust. Otherwise, the survival rate of silkworms will be affected.

5. The process of raising silkworms is very hard. Silkworms need to eat mulberry leaves day and night, and as they grow older, the amount of mulberry leaves they eat increases.

6. Silkworms usually spin cocoons in about a month. Before spinning cocoons, we need to build a frame and let them go up the mountain. It will take about two or three days for the silkworms to spin a snow-white cocoon.
