CATDOLL : CATDOLL: What methods are generally used for raising silkworms in greenhouses?

1. What are the common ways to raise silkworms in greenhouses?

There are two common ways of laying silkworms in greenhouses: manual laying and automatic laying.

Artificial cocooning is not widely used in major silkworm-raising areas in my country at present, mainly because it is time-consuming and labor-intensive, and the labor efficiency is too low. When artificial cocooning is used, early-maturing silkworms should be selected and cocooned first, and immature green heads should be selected from a large number of silkworms when they are fully mature. The immature green heads should be raised separately for 0.5 to 1 day to mature silkworms, and then cocooned.

Automatic cocooning is a common method used by silkworm farmers. When using automatic cocooning, when there are 20% to 30% of silkworms that are suitable for maturation (no residual mulberry leaves), use "Disease Prevention No. 1" or fresh lime powder to disinfect the silkworms, and then feed them a thin layer of mulberry leaves, and then place square cocoons or folded cocoons and centipede cocoons, so that the mature silkworms can automatically climb the cocoons and make cocoons. In addition, automatic cocooning can also use mature silkworm cocooning agents, and the use of hormone agents can improve the efficiency of cocooning. When the silkworms are 10% mature, adding molting hormones (cocooning agents) can make the silkworms mature uniformly, speed up the cocooning speed, and reduce the number of wandering silkworms. For silkworm varieties that have the habit of making cocoons on the upper layer, adding molting hormones (cocooning agents) can prevent the silkworms from climbing up randomly, so it is more ideal. The use of molting hormones must be controlled in an appropriate amount and at the right time, otherwise it will have adverse consequences. Generally, dissolve one ecdysone injection in 2 kg of clean water, stir it thoroughly, and then use a sprayer to spray the liquid on about 15-20 kg of fresh mulberry leaves. Add food when they are about 10% ripe, and they can be clustered after about 10 hours.

2. Silk fabrics, lacquerware, sericulture technology, metallurgical technology, pears, walnuts, grapes, carrots, peaches (which ones were transported to the Western Regions via the Silk Road)?

Silk fabrics, lacquerware, sericulture, metallurgy, pears, peaches, and the rest were introduced to my country from the Western Regions.

3. How to raise silkworms so they won’t die

Put it in a paper box or a small sieve for sifting rice. If using a sieve, put some paper at the bottom of the sieve.

When the silkworms have just hatched from eggs, you need to be especially careful with them, feed them with relatively tender mulberry leaves, and use a very soft brush to move them when changing mulberry leaves, and pay attention to the strength; sometimes the mulberry leaves are too dry, and if you are not careful, the silkworms will be left on the mulberry leaves that are about to be discarded during the process of changing mulberry leaves. It is a little difficult to raise them when they are young, but it will be easier to handle when they grow up.

When it is about to make a cocoon, just take some wheat straw and tie it into the shape of branches.

After the moths break out of their cocoons, place them together in a box. They will mate together and lay eggs. Sometimes, because there are few silkworms, some moths will be left alone when they break out of their cocoons, but don't worry, as long as you have a pair of silkworms, I believe it will be enough for you to raise.

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 store 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 after eating them, and they may even die.
