Key points of rearing large silkworm in autumn
The main reason for instable production of silkworm in autumn is silkworm disease. With the increase of silkworm rearing times, the number of pathogens increased, the spread area increased, the virus was fresh and reproduced quickly, and the pathogenicity was high. If the silkworm rooms and silkworm tools are not disinfected thoroughly, the management of rearing is relaxed, and the silkworm is in a bad environment of high temperature and humidity or high temperature and dryness in autumn, the mulberry leaves are poor in quality, and the silkworm disease resistance is weak. These are the main reasons for the outbreak of silkworm diseases in autumn. 1. Strengthen disinfection to prevent diseases and eliminate the source of diseases. Effective measures to prevent silkworm diseases are disinfection and elimination.

The law of cocooning in silkworm spinning
The life of silkworm goes through four stages: egg, larva, pupa and adult. The larval stage of silkworm is called the stage of silkworm baby. Sericulture usually refers to the rearing of larvae. The larvae go through four molting times from hatching to cocooning. As a result, the process of the larva is divided into five instar stages. For a period of time before molting, silkworms do not eat or move, which is called sleeping. From the first to the fourth instar, the silkworm sleeps four times, and the fifth instar silkworm no longer sleeps in the later stage, but forms a cocoon and pupates in the cocoon, thus completing the larval stage of the silkworm. The newly hatched silkworm is called ant silkworm, which has just molted its skin.

Qiuhua × Ping 30, a new autumn male silkworm variety bred by the sericulture Research Institute of Zhejiang Academy of Agricultural Sciences, has the advantages of strong physique, uniform sleep of all ages and easy rearing. The number of ants per gram is about 2310, and the 5th instar passes through 6 days and 18 hours. After 22 and a half days, the two-day hatching rate is 49.34%, the silk length is about 1240 meters, the cocoon shape is oval, large and uniform, the cocoon color is white, and the cocoon shell rate and silk emergence rate are high. (2) the main points of feeding and breeding techniques. The ant harvester is sensitive to light.

The main feed of silkworm is mulberry leaf. Because the quality of mulberry leaf varies greatly in different seasons, it has a great influence on the yield and quality of cocoon. If the summer and autumn silkworms are fed with nutrition, the yield can be increased by 10% to 20%. The formula technology is introduced as follows: 1. Formula and feeding method of feeding agent. ① glucose solution additive. During the silkworm rearing period, if there is continuous overcast and rainy weather, the texture of mulberry leaves is tender due to lack of light, the moisture content is high, and carbohydrates are reduced. At this time, the picked mulberry leaves can be sprayed with 5% glucose solution and fed to silkworms after drying.

Cocoon collection and sale of silkworm
1. The suitable time for cocoon collection: after the cocooning of mature silkworm, molting and pupation, with the development of pupa, the skin becomes hard and the skin color becomes darker, when the skin color changes to yellow, it is the suitable time for cocoon collection. The spring silkworm period is 6-7 days after the upper cluster. The summer and autumn silkworm period is 5-6 days after the upper cluster, and the late autumn silkworm period is 7-8 days after the upper cluster. The cocoon is picked too early, the silkworm has not yet pupated, the hairy foot cocoon is not easy to be evenly baked during cocoon drying, the cocoon quality is reduced, and the hairy foot cocoon is easy to seep the dirt out of the cocoon layer during cocoon cooking, which makes the color of raw silk worse.
