Technological innovation empowers the high-quality development of agricultural specialty industries. Sichuan Lezhi’s sericulture industry is on the fast track
Recently, the reporter came to the Lezhi Bombyx Silkworm Industrial Park Base in Gaosi Town, Lezhi County. In the silkworm room next to the base, white and plump zombie silkworms were stretching and squirming on the silkworm bed. In a few days It will become rigid and enter the next production process.
“White Bombyx silkworm is a traditional Chinese medicinal material that has the functions of dispelling wind and heat, stimulating menstruation and activating meridians.” Jiang Xiwu, general manager of Sichuan Derenyuan Agricultural Technology Co., Ltd., told reporters that the economic benefits of breeding White Bombyx silkworm are considerable, but The quality of zombie silkworms is closely related to technology. From mulberry tree planting and silkworm rearing to fungus cultivation and silkworm inoculation, a chain reaction occurs one after another. It is necessary to accurately time the silkworms to become fossilized, so large-scale and professional breeding of white zombie silkworms is required. Silkworms, the technical difficulty is not small. “The same strain of bacteria will produce different results under different humidity and temperature.”
How to refine the control range to “a certain value”? The academician (expert) workstation has played an important role. According to reports, Li Min is an expert in certification and inspection of my country’s Chinese herbal medicine productionquality management practices (national GAP) and a second-level professor at Chengdu University of Traditional Chinese Medicine. “Under his guidance, We quantified each production step and selected several high-quality strains from more than a thousand strains.” Small trials in 2017, pilot trials in 2018, and production trials in 2019… After repeated trials, the The company’s technical staff finally overcame the bottleneck of growing zombie silkworms, and a set of standardized breeding guidelines accurate to two decimal places was born. The company embarked on the road to large-scale breeding in 2020.
Members of the academician (expert) workstation include Wan Yongji, professor and doctoral supervisor of Southwest University, and Li Lixia, teacher of the Department of Pharmacy, School of Veterinary Medicine, Sichuan Agricultural University, Ph.D., practicing pharmacist, and master’s supervisor. With experts on silkworm disease Science and disease prevention and control technology, applied microbiology and biotechnology, Chinese medicinal material varieties, quality evaluation and Chinese medicinal material GAP base construction and other fields have escorted and checked the situation. The company has achieved a series of outstanding achievements: “Lezhi Bombyx Silkworm” has passed the geographical indication certification For trademark certification, the company applied for 5 invention patents, revised 2 items and added 4 new items based on the 2015 edition of the Pharmacopoeia, and participated in the formulation of industry standards and group standards for zombie silkworms.
The company’s standardized breeding technology has been further expanded after optimization, and it has reached cooperation with cooperatives and large breeding households in Yunnan, Guizhou, Chongqing and other places. Currently, the company has more than 2,000 acres of mulberry garden base and tens of thousands of acres of cooperative bases. , the comprehensive annual output value of sericulture reaches more than 10 million yuan.
“It is with the support of the academician expert workstation that our zombie industry can achieve such great achievements in a short period of time.” Jiang Xiwu is full of confidence in the future. He firmly believes that the company will work with the expert team to promote the development of the sericulture industry. On the fast lane of high-quality development.
This is a vivid epitome of how academicians and experts’ talents promote the entire industry chain of the sericulture industry in Lezhi County scientific and technological innovation. It is understood that the Ziyang City Agriculture and Rural Affairs Department has listed the sericulture industry as a characteristic industry, providing key support and cultivation, and actively promotes the gathering of scientific and technological resources and high-quality talents from universities to Ziyang. Lezhi County organized enterprises related to the sericulture industry to sign industry-university-research collaborative innovation agreements with Sichuan University, Sichuan Agricultural University, Sichuan Provincial Silk Research Institute and other scientific research institutions, and established municipal academicians 3 (expert) workstations, as well as a natural product research and development center and a cocoon and silk fiber engineering technology research center, introduced 10 professors and researchers to conduct product research and development and result transformation, and developed large-scale products such as Lezhi Bombyx mori, silkworm excrement (mulberry branch) extract chlorophyll, etc. More than 30 kinds of health products. Promote the added value of sericulture products to increase by more than 30%. Thanks to technological innovation, in 2021, the comprehensive output value of the agricultural part of Lezhi’s sericulture industry reached 446 million yuan, the output value of the comprehensive utilization of industrial and sericulture by-products was 1.096 billion yuan, and the output value of the entire sericulture industry chain exceeded 1.5 billion yuan.
