CATDOLL : CATDOLL: What are the 6 techniques for raising silkworms?

1. How to raise silkworms?

Steps/Methods

1. Preliminary preparation: Prepare the silkworm room and silkworm tools after planting mulberry leaves; 7 days before raising silkworms, spray and disinfect with 1% strong chlorine, half a pound of liquid per square meter, and seal it for more than 24 hours after spraying. At the same time, the environment around the silkworm room should be sprayed and disinfected.

2. Mulberry leaves: When raising silkworms, it is important to note that the mulberry leaves should be fresh. Do not use mulberry leaves that have been stored for too long for feeding. Stale mulberry leaves can easily cause diseases in the silkworms.

3. Temperature: Silkworms are temperature-changing animals, and their adaptability range is 20-30℃. In the spring, silkworms often encounter low-temperature and humid climates, so the focus is on replenishing warmth and removing moisture. In the summer, silkworms encounter high-temperature and high-humidity climates, so the focus is on cooling and removing moisture, keeping the air in the silkworm room flowing, and removing stuffiness. In the autumn, if the weather is hot and dry, you need to replenish moisture indoors.

4. Accelerate the growth of silkworm eggs: About the eighth day after the silkworm eggs are taken out of the warehouse, you can see a small black dot at one end of the egg, which is called the green dot. If 20% of the eggs on a sheet of silkworm eggs have the green dot, use a black cloth to block the light. Counting from the day of the green dot, remove the black cloth at 5 o'clock in the morning on the third day and turn on the light for photosensitive incubation.

5. Disease prevention: Silkworms are prone to many diseases, so prevention is generally the main approach. After an illness occurs, special agents should be used for disinfection. At the same time, sick silkworms should not be thrown around randomly, as they are highly contagious.

6. Management: When feeding mulberry leaves, it is best to feed 2-3 times a day. Secondly, no incense is allowed in the breeding room, and mosquito coils, perfumes and other things with strong odors are not allowed to be placed in the breeding room to prevent the death of the silkworms.

7. Hygiene: When there is too much accumulation of silkworm feces, bacteria are very easy to breed and spread. Silkworm feces must be cleaned up in time, usually on the same day. In addition, the silkworm skins shed and the leftover mulberry leaves must be cleaned out in time.

2. Tips for raising silkworms for children?

1. From silkworm ants to silkworm babies:

Suitable temperature: 20-25℃, time: 2-3 days for incubation.

Collecting ants: The little silkworms will crawl out of the egg shell like ants. Use very light gestures to collect and lead them to the tender leaves.

Note: Silkworm eggs need to be kept in a ventilated and dark place during hatching period.

Method/Step 2:

2. Feeding silkworms:

The living habits of silkworms are: sleep when full, eat when awake;

Living environment: Plastic or wooden flat box,

Note: The mulberry leaves should be fresh. You can also collect them in a plastic bag each time, use a few leaves every day, and sprinkle some water on the rest and put them in the refrigerator to keep them fresh. The collected leaves will have some dust, so you can wash them and dry them. You must dry them, otherwise the young or adult silkworms will have diarrhea if they eat them.

Method/Step 3:

3. Silkworms spin silk and make cocoons:

Molting: After molting once, the larvae become the second-instar larvae. Each time the larvae molts, they become one year older. They molt a total of four times.

Cocooning: 7-8 days after molting four times, the owl stops eating mulberry leaves, its body starts to shine, and it begins to look for a suitable place to start cocooning.

Note: Put some supporting objects in the silkworm box to help the silkworms make cocoons.

Method/Step 4:

4. About silkworm droppings:

Silkworm feces, which consist of black particles, can be used as medicine in traditional Chinese medicine and are also a good nutrient for plants.

Silkworm excrement, also known as silkworm sand, has the effects of curing dampness, curing itching, removing internal heat, removing rheumatism, and improving hearing and eyesight. Many elderly people dry it and make it into pillows for their newborn babies to sleep on.

Method/Step 5:

5. Silkworms emerge from their cocoons:

The silkworm sheds its skin for the final time (fifth time) in the cocoon and becomes a pupa. After about 7-10 days, the pupa turns into a silkworm moth and emerges from the cocoon.

Note: The fat one is the mother of the silkworm, and the thin one is the father of the silkworm. Let the father and mother of the silkworm live together, and you can see a lot of silkworm eggs the next day. If you protect them well, these silkworm eggs can hatch again in the spring of the next year.

Method/Step 6:

6: Note: Silkworms are particularly sensitive to fragrance, so perfume, mosquito coils, air purifiers, scented cosmetics, etc. are not allowed. Any type of pesticide is absolutely prohibited! Raising silkworms can stimulate children's creativity, interest, and touch life, which is conducive to improving children's hands-on ability and observation ability. It is also a good content of family affection activities. The following is a picture of the harvest of our silkworm raising~~

3. 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.

4. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

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.

6. What are the tips and things to note when raising silkworms?

1. Silkworms are still easy to buy, but if you have no experience, it is not recommended to start from unhatched eggs, as they have higher requirements for temperature and humidity, and the whole process takes less than 30 days.

2. It is recommended to start from the second or third instar. The survival rate is high and it is easy to handle. Otherwise, if the silkworms are too young, you have to be very careful when putting mulberry leaves every day. It is really troublesome to change mulberry leaves for ant silkworms.

3. In the early stage, you can find a paper box to raise it, and spread mulberry leaves on the bottom of the box, and spread 2 layers. Mulberry leaves are generally changed every 1-2 days, and the old leaves in the box should be cleaned out.

4. You can cover the box with plastic wrap and then use a toothpick to make a few holes in it. Put the box in a cool place away from direct sunlight. Adult silkworms have a strong ability to adapt to the environment.

5. In reality, mulberry trees are not easy to find, so they are mainly purchased online. They can be placed in the refrigerator at 0 degrees to keep fresh. Take them out of the refrigerator before each use and moisten them with clean water.

6. Raising silkworms is relatively easy as long as there is sufficient food. If you just want to complete the operation, you can put them in a box during the cocooning period. Otherwise, you need to find a slightly larger box and put some small wooden racks to facilitate cocooning.

7. 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.
