Exploration of the Belly Characteristics of Living Cocoons Grown in Repeated Seasons

Abstract

The article examines the influence of climatic conditions on the technological characteristics of local and Chinese silkworm hybrids (Chofuun Bayye) grown in spring, summer and autumn in the Surkhandarya region. Scientific research was carried out to improve the technological properties of the re-grown cocoon shell and the quality of raw silk, as well as to develop a primary processing technology. The lack of industrial methods of growing cocoons has led to a decrease in attention to the care of mulberry leaves, the nutritional properties of mulberry leaves change during the summer, where it is studied to what extent climatic conditions during feeding affect the yield of raw silk.

In the course of the study, the average porosity of the shell of local cocoons by seasons was 76.32% in spring, 50.55% in summer and 36.08% in autumn. Research has shown that the average seasonal porosity of the shell of Chinese hybrid cocoons is 67.35% in spring, 42.10% in summer and 34% in autumn. The comparison results are presented in the form of a histogram. The shell porosity of local cocoons grown in spring was 8.97% higher than that of cocoons grown in summer; the porosity of the shell of cocoons grown in summer was 8.45%, and the porosity of the shell of the cocoons was 2.08% higher in autumn.
