Silkworm speed four measures

1. Give silkworms tonics

Studies have shown that special injections are used as dilutions and sprayed on mulberry leaves to make silkworms happy. It is also possible to spray this solution directly on the silkworm body and allow the silkworm skin to absorb the nourishment of “tonic”. After processing silkworms, silkworms are strong, have large knots, produce more silk, and have better quality.

This special injection is made with insect hormones. There are two kinds of commonly used: one is called "progesterone hormone", the main component is chemical terpene; the other is called "ecdysteroids", which is composed of chemical substances such as steroids. Both of these hormones have been artificially produced.

We should seize the fifth instar stage of a large number of silkworm silkworms, and add “pro-nutrition hormones” to it to make it “juvenile” and slow down. “Huanyan” grow old, eat more mulberry leaves, and produce more silk. This is the way to extend the age of five, and it is very effective in increasing silk production.

When silkworms reach the end of the fifth instar, and when mature silkworms reach 5%-10%, each silkworm strain once uses 1 ampoules (2 kg of ecdysone plus water and mixes evenly on mulberry leaves) once after feeding. , continue to give Sang 2 times - 4 times. Practice has shown that adding ecdysone to silkworm has the following effects: 4% reduction in mulberry production and 1.9% increase in mulberry production. In particular, the use of ecdysone in the absence of leaves and severe disease in the late silkworm can reduce the loss of silkworms and dead silkworms. The silkworms are old and ripe, and they are convenient on the clusters and save a lot of labor. There are no green heads, no tussahs and silkworms.

2. Silkworm Adds Triacontanol

Studies on the addition of triacontanol to silkworms by the Xianju County Forestry Bureau in Zhejiang Province showed that silkworms can increase the activity of amylase, protease and transaminase by increasing the amount of triacontanol in silkworms and promoting mulberry leaves. Proteins and starches are converted into silk proteins, accelerating the accumulation of silk material, increasing the layer rate of worms, increasing the mulberry value by 14%, and increasing the value of each silkworm by 14.5%, while the cost is very low.

3. Japan uses artificial feed for sericulture

After years of research, Japan has made silkworm artificial compound feed to replace mulberry leaves. The feed is mainly made by mixing 10 ingredients: 20% for mulberry leaf powder, 40% for soybean protein powder, 5% for sucrose, 8% for cellulose, 8% for starch, 8% for yeast, 2.5% for citric acid, and 0.5% for antibiotics , Sterol 0.5%, a little inorganic salt. Feeding silkworms with artificial feed is not only convenient to use but also has high nutritional value and can save a lot of mulberry fields.

4. Cornmeal feeding silkworm can improve the quality of silk

Indian scientists have found through experimentation that feeding silkworms with yellow cornmeal can promote the growth of young silkworms and increase silk production. According to reports, feeding silkworms with synthetic foods such as yellow cornmeal can reduce the food cost of feeding silkworms, and can also improve the survival rate of silkworms, and the silk yield can be increased by 10%-15%. Yellow cornstarch contains sterols of starch and oil, which facilitate silkworm digestion and can be used to replace traditional mulberry leaves and foods made from starch and soybean oil that are currently fed to silkworms.
