Shiquan County, Shaanxi Province innovates and develops sericulture industry

Since this year, the Sericulture Development Service Center of Shiquan County, Shaanxi Province has followed the positioning of the county party committee and the county government to optimize and strengthen the sericulture industry, with the theme of high quality development , with transformation and upgrading as the main line, and in accordance with the development ideas of “strengthening the primary industry, strengthening the secondary industry, optimizing the tertiary industry and synergy of the tertiary industry, cross-border integration, and diversifying business formats”, innovation-driven Transform and upgrade the sericulture industry, accelerate the application and promotion of new technologies, and closely focus on the idea of ”project is king, innovative development” to establishintelligent and large-scale co-cultivation of small silkworms and a demonstration model for labor-saving raising of large silkworms, improve the quality of sericulture, shorten the sericulture cycle, achieve multi-batch sericulture throughout the year, expand the total amount of sericulture, and promote the revitalization, upgrading and high-quality development of the sericulture industry.

First, the “Shiquan County Artificial Feed Breeding Feed Distribution Center” was first established in the province, from site and operation room disinfection to feed proportioning, bagging, cooking, cooling, refrigeration, packing, distribution, and distribution. The center strictly follows the “Operating Procedures for Breeding Artificial Feed for Small Silkworms” and meticulously implements it to ensure the quality and quantity (each piece of feed According to the weighing ratio of the first and second instars), 125 young silkworms were raised at 4 young silkworm demonstration sites in the county this spring, and achieved good results.

The second is to take the lead in implementing the sericulture insurance pilot project in the province. It aims to enhance the ability of sericulture farmers to resist natural risks and silkworm disease risks in the sericulture production process, ensure the income of sericulture farmers, and promote the sustainable, stable and healthy development of the sericulture industry in Shiquan County. Before sericulture, silkworm farmers pay an insurance premium of 32 yuan per silkworm. During the sericulture period, if the silkworms suffer from stiffness, pus disease, bacterial disease, particulate disease, arthropod disease, poisoning, high and low temperatures and are unable to form cocoons, and In the event of fires, wind disasters, lightning strikes, heavy rains, landslides, building collapses, etc., silkworm farmers should report insurance promptly. After the insurance company verifies the insurance on site, the insurance company will pay a compensation ratio of 20% to 100% according to the age of the silkworms. Zhang Silkworm’s maximum compensation is 800 yuan. Shiquan County has 97 households with 231.5 insurance policies for summer silkworm breeding in 5 towns.

Third, it was the first in the province to issue the “Management Rules for the Co-cultivation of Small Silkworms”. The co-breeding of silkworms in Shiquan County has grown from 2 towns and 3 co-breeding sites in 2010, with a total of more than 100 co-breeding sites, to 22 co-breeding sites in 8 towns in the county, with a total of 13,568 co-breeding sites in 2021. The standardized and operable “Shiquan County Silkworm Co-breeding Management Rules” were formulated. At the beginning of this year, in order to further standardize the management of the production and operation of small silkworm co-breeding in Shiquan County, improve the scale and quality of co-breeding, and realize the co-breeding of small silkworms, To create a win-win situation for both the breeding business entities and the silkworm farmers participating in the co-breeding, the “Shiquan County Silkworm Co-breeding Management Rules”, “Small Silkworm Industrial Breeding Technology Operating Procedures”, “Types and Methods of Disinfection Drugs for Silkworm Houses and Silkworm Tools”, “Disinfection Drugs for Silkworm Body and Seats” and Methods” and “Methods for Disinfection of Silkworm Body and Seat Disinfection of Small Silkworms”, which further standardizes the operating procedures and various aspects of co-breeding of small silkworms from the aspects of application conditions, main responsibilities and obligations, supervision, management and assessment, rewards and subsidies, identification of co-breeding responsibilities, etc. technical operating procedures.

The fourth is to take the lead in promoting “two-stage co-cultivation and three-stage sericulture” in the province. At present, the co-breeding of young silkworms in Shiquan County means that after the 3-year-old silkworms are fed, they are distributed to each household for breeding. Since most households have extensive management of rearing 3- and 4-year-old silkworms, 3- and 4-year-old silkworms are very susceptible to silkworm diseases and high disease. , The resistance to low temperature is weak. In order to solve these problems, the county sericulture center will select five qualified small silkworm co-breeding sites in Zhongchi, Chihe, and Ironing starting from spring this year to co-breed the young silkworms to the fifth age, and then distribute them to demonstration households for breeding. Because large silkworms are highly resistant to silkworm diseases and adverse environments, they are less likely to get sick and reduce production, and the technical treatment is simple and easy to raise. Silkworm farmers only need to raise large silkworms for 5-7 days before they can spin cocoons. Silkworm farmers laugh and call it “7 days of happiness” “Style silkworm rearing”. At present, 87 “two-stage co-breeding and three-stage sericulture” have been promoted in spring and summer, and the average yield in spring reaches 95-120 kilograms.

By taking the above innovative measures, Shiquan County has gradually solved a series of practical problems faced by the sericulture industry, such as the aging of sericulture farmers, the shrinking number of sericulture households year by year, and the great impact of weather on mulberry leaves in spring and autumn, and stimulated new impetus for the development of the sericulture industry.
