Problems solved by technology

[0002] Silk has a wide range of uses and is more and more recognized by people. However, there are many deficiencies in the existing silkworm breeding technology. Usually, fresh mulberry leaves are picked and directly used to feed silkworms. However, it is found that the growth speed of most silkworms is too high. slow, cocoon production and cocoon production are not ideal, causing huge economic losses to silkworm farmers; benefit

Abstract

The invention belongs to the technical field of breeding of silkworms and particularly relates to a breeding method for improving the quality of cocoons produced by the silkworms. The method specifically includes the following steps of (1) breeding and management of the silkworms from the 1st age period to the 3rd age period; (2) breeding and management of the silkworms from the 4th age period tothe 5th age period. According to different physiological properties in different stages, breeding and management are carried out in different stages, healthy fast growth and development of the silkworms can be effectively facilitated, robust development of silk glands is promoted, and complete formation of silk protein is achieved; before feeding with mulberry leaves, the mulberry leaves are soaked in a soaking liquid to maintain fresh, the growth and development of digestive organs are effectively facilitated, the absorption conversion rate of the silkworms is increased, the disease and bacteria resistance capability of the silkworms is enhanced, and correspondingly the silkworms are robust. Moreover, under combination with illumination treatment, uniform growth of the colony is facilitated, conversion and synthesis of the protein are effectively promoted, the yield of the cocoons is increased, the quality of the produced cocoons is improved, and silk is flexible, smooth and elastic.
