I am happy to answer your question. Please forgive me if there are any mistakes.

2. I want to buy some silkworms. I want to ask: How to raise silkworms? Please teach me!

Raising silkworms is not complicated. First, the mulberry leaves should be cleaned and not have any water on them, otherwise the silkworms will die. Cut the mulberry leaves into square pieces, about 1cm×1cm. If a silkworm's skin is yellow and it is praying, it means it is going to sleep and should be separated from other silkworms. At this time, it will not eat. Don't worry.

3. Tips for raising silkworms

After receiving the silkworm eggs, place them in the prepared silkworm rearing box. The silkworm box can usually be made of ordinary paper boxes, but it must be clean and odorless. From the date of shipment, the silkworm eggs will naturally hatch into silkworms in about 11 days (including shipping 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 into the silkworm box. The silkworms will automatically climb onto the mulberry leaves to eat. It usually takes about 27 days for silkworms to hatch and cocoon on the mountain (divided into 5 ages). It is better to use tender mulberry leaves to feed silkworms from the first to third ages, and ordinary mulberry leaves can be used 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 their most suitable growth temperature is around 27 degrees Celsius. A silkworm eats about 25 grams of mulberry leaves in its lifetime. If you feed 40 silkworms, you only need 1 kilogram of mulberry leaves. But in the actual feeding process, some mulberry leaves will be wasted, so more mulberry leaves will be needed.

After the fifth instar, silkworms 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 hills or pine branches are generally used as silkworm hills. For silkworms raised as pets, a paper box divided into many small compartments can be used instead.

Precautions for raising silkworms

1. Mulberry leaf preservation

1. Place the mulberry leaves in the refrigerator (around 5 degrees Celsius) to prevent them from spoiling.

2. Tie the mouth of the plastic bag tightly to slow down the drying and dehydration of the mulberry leaves.

2. Feeding of Silkworms

1. After taking out the mulberry leaves from the refrigerator, you need to wait for a few minutes to allow the mulberry leaves to return to room temperature before feeding them.

2. Do not wash the mulberry leaves with water, keep them in their natural state.

3. When feeding second-instar silkworms, please use tenderer mulberry leaves, 1-2 leaves per day.

4. 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 house should be placed in a cool place (around 25 degrees Celsius).

5. How to raise silkworms? It would be best to explain in detail

Leaves for young silkworms: For 1-year-old silkworms, use the third leaf from the top bud, the leaf color is yellow with green, and one silkworm seed uses 1kg of leaves; for 2-year-old silkworms, use the fourth leaf from the top bud, the leaf color is green with yellow, and one silkworm uses 3kg of leaves; for 3-year-old silkworms, use the fifth to sixth leaves from the top bud, the leaf color is light green and shiny, and one silkworm uses 10 to 12kg of leaves; for 1st and 2nd-year-old silkworms, cut the mulberry leaves into small cubes 1.5 times the length of the silkworm body, and for 3rd-year-old silkworms, cut the mulberry leaves into triangles for feeding. The amount of mulberry leaves fed each time should be controlled to leave a small amount of residual mulberry leaves on the silkworm seat before the next feeding. Adult silkworms: Reasonable mulberry feeding: 4th-year-old silkworms are the transition period from the growth of the silkworm body to the growth of the silk gland. If they are malnourished, it will affect the yield and quality. The mulberry leaves should be fresh and of good quality. 7 to 15 leaves under the top bud should be selected for feeding to achieve the goal of good mulberry. The amount of mulberry used by the 5th-instar silkworms accounts for about 85% of the total amount of mulberry used. This period is the key period for rational use of mulberry and improving the benefits of mulberry leaves. The feeding method of tight at both ends and loose in the middle is adopted: on the 1st to 2nd day or the 5th to 7th day of the 5th instar, the amount of leaves given should be strictly controlled until the silkworms have just finished eating the mulberry leaves next time; on the 3rd to 6th day, the silkworms should be fully fed with good mulberry. Each time the leaves are fed, the silkworms are moved and the seats are expanded to keep the silkworm heads even. 4. Keep the silkworm seats clean: Use fresh lime powder to disinfect the silkworm bodies and silkworm seats every morning during the adult silkworm period. On rainy days with high humidity, sprinkle lime powder twice a day to keep ventilation and dry.
