1. How to breed silkworms?

Hello,

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, and there are 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.

2. How to raise silkworms at home?

After receiving the silkworm seeds, place them in the prepared silkworm rearing box. The silkworm box can generally be an ordinary paper box, but it must be kept clean and odorless. From the day the silkworm seeds are shipped out of the warehouse, they will naturally hatch into silkworms in about 11 days (including the delivery time) at room temperature of 21-29 degrees Celsius. Silkworms will have an appetite about 40 minutes after hatching, and the feeding process should begin at this time. Take the prepared fresh tender mulberry leaves out of the refrigerator, wait for the mulberry leaves to return to room temperature, cut them into small pieces with a knife and put them in the silkworm box. The silkworms will automatically climb onto the mulberry leaves to eat. It usually takes about 27 days (divided into 5 ages) for silkworms to hatch and cocoon on the mountain. It is advisable to use tenderer mulberry leaves for feeding silkworms from the first to third ages, and ordinary mulberry leaves for silkworms from the fourth and fifth ages. Silkworms are suitable for growing in an environment with a temperature range of 22-29 degrees Celsius, and the most suitable growth temperature is about 27 degrees Celsius. A silkworm eats about 25 grams of mulberry leaves in its lifetime. For example, if you want to feed 40 silkworms, you only need 1 kg of mulberry leaves. However, in the actual feeding process, some mulberry leaves will be wasted, so more mulberry leaves will be needed. After the fifth instar, silkworms will stop eating mulberry leaves and start looking for a suitable place to spin silk and make cocoons (also called going up the mountain to make cocoons). In rural areas, straw-bound grass hills or pine branches are generally used as silkworm hills. For silkworms fed as pets, a paper box divided into many small compartments can be used instead. Precautions for raising silkworms 1. Keep mulberry leaves fresh 1. Place mulberry leaves in the refrigerator (about 5 degrees Celsius) to prevent deterioration. 2. Tighten the plastic bag to slow down the drying and dehydration time of mulberry leaves. 2. Feeding silkworms 1. Take out the mulberry leaves from the refrigerator and wait for a few minutes for the mulberry leaves to return to room temperature before feeding. 2. Do not wash the mulberry leaves with water and keep them in a natural state. 3. For feeding the second-instar silkworms, please choose tenderer mulberry leaves, 1-2 pieces per day. 4. The feeding time can be chosen in the morning or at noon. 3. Other matters needing attention 1. Do not catch silkworms with your hands, use the soft bristles of a brush to drive them away; 2. Clean the silkworm room every day; 3. The silkworm room should be placed in a cool place (around 25 degrees Celsius).

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 do beginners raise silkworms?

Breeding for beginners

When a novice raises silkworms, he needs to prepare a clean, odor-free ordinary paper box or wooden box, then put the purchased silkworm eggs into the paper box, and place the box in a greenhouse that can regulate the temperature. The indoor temperature should be controlled between 21-29 degrees to promote rapid hatching of the silkworm eggs.

Feeding mulberry leaves

Silkworms grow very fast and have a high demand for mulberry leaves. When raising silkworms, you need to prepare fresh, pesticide-free green mulberry leaves. Use a sharp knife to cut the mulberry leaves into small pieces, and then spread them on the box. Allow the silkworms to eat freely, and feed them mulberry leaves every 3-4 hours to ensure that there is enough food.

Suitable environment

Silkworms live in a clean environment. When raising silkworms, if the environment is too dirty, the silkworms will be infected with diseases. The boxes need to be cleaned every 2-3 days. The feces and leftover mulberry leaves in the boxes can be cleaned out, and the windows should be opened from morning to afternoon every day to ventilate the silkworms.
