High-quality cocoon production "three levels"

First, to raise the barriers to health should strengthen the measures to eliminate the virus, prevent and control the damage of silkworm diseases, prevent all kinds of silkworm poisoning incidents, and ensure the safety and health of silkworms. It is necessary to strengthen the feeding management so that the selected good mulberry and the plentiful satiety can be prevented and hungry. In particular, after the third instar of the fifth instar, it is better to allow the silkworm to eat well and prevent the low temperature below 24 degrees Celsius, so as to promote the full growth of the silk gland and improve the leaf silk conversion rate, laying the foundation for the high yield and quality of the silkworm cocoon.

Second, to put the good harvest in front of the pick, the carcass should be first checked, the carcass becomes yellow-brown for the appropriate pick, picking early, the younger children have not yet phlegm or just phlegm, in tenderness, At this time, it is very easy to pick up bleeds, cause pollution to the stratum corneum, become oily after drying, and reduce tannin quality and price. The picking time is generally 5 to 6 days after the upper silkworms in spring, 4 to 5 days in summer and autumn, and 7 to 8 days in late autumn. When picking, pick up dead silkworms and grubs to avoid contamination. It is necessary to be gentle and light in order to prevent damage to the carcass and increase the amount of ink inside, resulting in unnecessary losses. At the time of picking, they should be placed on the top, bottom, double palace, and emerald, and sold separately.

Third, the fresh oysters sold under good conditions should be thinly laid in the silkworm cocoons and cannot be piled up too high. When sold out, it is required to be shipped in baskets, and the air cylinders are inserted in the middle to facilitate ventilation and prevent extrusion. It is strictly forbidden to use plastic bags and snakeskin bags or film pockets to load cocoons. In the process of transportation, light loading, light transport, and light discharge should be done to prevent carcass injuries and squatting. On the way, we must also pay attention to prevent the sun and rain.
