Science and technology commissioners went to Hechi City Silkworm Breeding Farm to guide silkworm breeding work
On November 2-3, a five-member team of science and technology commissioners from the Guangxi Sericulture Technology Promotion Station went to the Hechi Silkworm Breeding Farm to provide scientific and technological services.
Hechi Silkworm Breeding Farm has an annual production capacity of 300,000 first-generation silkworm hybrids and 30,000 original silkworm seeds. The science and technology commissioner listened to the introduction of the production situation in the second half of this year by the technical person in charge of the Hechi Silkworm Breeding Farm. After on-site inspection of the first-generation hybrid cocoon protection, cocoon cutting, and male and female identification of silkworm pupae, he put forward several guiding opinions: 1. It is to strengthen the work of cocoon and pupa selection in the “five selections”, select and retain individuals and groups with cocoon type, cocoon color, pupa body color, and body shape that are in line with the characteristics of the variety, and have high robustness to improve silkworm speciesQuality; The second is to protect the seed cocoons and silkworm pupae. Now that it has entered November, the weather has turned cooler, the temperature difference between morning and evening is large, and the climate is dry. Timely heating and moisturizing is required at night to ensure adequate growth and development. temperature; the third is to regulate the hair moths, try to make the male and female moths of the mating species emerge in equal numbers on the same day, protect the male moths, ensure the matching effect, and improve the yield and quality of silkworm seeds.
