Silkworm breeding and breeding are two parts of the work of silkworm breeds that are connected before and after, and are not only different but also related to each other. Silkworm breeding is actually the continuation of silkworm breeding. The task of silkworm breeding is to incorporate the current silkworm varieties and new breeds into the breeding plan based on the needs of silkworm cocoon production, to provide high-quality silkworms to meet the needs of cocoon breeding in rural areas, and to maintain the breeding environment at all levels of silkworm breeding. The species of the special envoys are maintained at a certain level.

The selection and promotion of fine silkworm species is only a prerequisite for comprehensive measures to increase the production of silkworm cocoons and requires the cooperation of other breeding and management conditions. Therefore, in the breeding process, we must pay attention to the quality of feed, disinfect the suitable environment, and strictly select a series of traits that can give full play to the excellent silkworm species. There is a correlation between the various traits of this thing, and the excellent silkworm varieties can not reach the level, so it is necessary to accurately evaluate the excellent silkworm varieties. And with the development of social economy and changes in demand, excellent silkworm varieties with different traits are required in different periods.

After the silkworm eggs are laid down, they hatch in the spring of the next year. It takes about 10 months for spring seeding in spring and 6 months for spring seeding in autumn. During this period, all physiological activities in the eggs are affected. The influence of external environmental conditions. Even if good silkworm eggs are obtained during seed production, the quality of silkworm eggs will be affected due to improper protection, resulting in increased dead eggs or degeneration of eggs, resulting in uneven embryonic development, poor hatching, and weak ant bodies and decreased vitality. Therefore, a dedicated person must be in charge, with someone on duty day and night, regularly record the indoor and outdoor temperature, adjust the reasonable protection temperature and humidity, and do a good job of preventing insects, rodents and mildew. The key point of silkworm egg protection is to ensure that the eggs’ diapause period and the cumulative number of days after the diapause period to withstand cold storage are greater than the number of days after spawning to the next year’s harvesting period, and provide uniform hatching for production. , High-quality silkworm eggs with healthy ant body.
