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 silkworm cultivation, and especially belongs to a breeding method for increasing yield and quality of cocoon of silkworms. The concrete method is as follows: (1) conducting feeding and management on silkworms in first, second and third instars; and (2) conducting feeding and management on silkworms in fourth and fifth instars. According to different physiological properties at different stages, feeding and management are conducted by stages, healthy and rapid growth and development of silkworm bodies can be effectively promoted, silk glands are promoted to develop, and a silk protein is fully formed; and mulberry leaves are soaked by a soak liquid before feeding is conducted to enable the mulberry leaves to be fresh, growth and development of digestive organs are effectively promoted, an absorption and transformation rate is increased, the disease resistance and the antibacterial ability are enhanced, silkworm bodies are strong, and light treatment is combined, so uniform population development is promoted, protein transformation and synthesis are effectively promoted, the yield and quality of the cocoon are increased, and silkworm silks are flexible, smooth and elastic.

Description

technical field [0001] The invention belongs to the technical field of silkworm breeding, in particular to a breeding method for improving silkworm cocoon production and cocoon quality. Background technique [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. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a breeding method for improving the cocoon yield and cocoon quality of silkworms.
