In late autumn, silkworms generally do not reach the cluster until mid-to-late October. At this time, the average indoor temperature is about 15°C, which is 8-9°C lower than the optimum temperature for the clusters on the silkworm. Therefore, warming work during the camping period should be done so that the cluster room temperature reaches 23.5-24°C. The benefits are: 1. Rapid heating and processing at the camping speed, which takes about 15 days from the start of the clustering on the silkworm to the end of silk spinning, and phlegm on the seventh day; normal temperature treatment (without warming), termination from the upper tuft to silk spinning It takes more than 7 days, and the eleventh day goes away. (2) The low residual fiber temperature at room temperature is low. The mature silkworm not only has slower spinning speed, but also has more residual cocoon filaments in the cockroach. Therefore, the total amount of heating and unheating is the same, but the former increases the amount of cocoon layer of the latter by 5%. The body weight is reduced by 3%. 3, cocoon quality high cluster room heating can eliminate moisture, make silkworm cocoon white, uncomfortable, and reduce dead clusters. Due to the high volume of cocoons, cocoons were tested for their dry shell content, and the average of the treated cocoons was 0.6 yuan higher than the unheated ones. The net heating cost was increased by 9.07 yuan per seed.
