The tussah silk industry in Northeast China is shifting from extensive farming to technology-driven practices. In mid-July, a team of experts from Jilin Province's tussah industry technology system visited Dongliao County to provide technical guidance on autumn seed production at three demonstration enterprises, directly impacting autumn silkworm yields and seed quality.
Industry Background
Tussah silkworm farming is a key specialty agriculture sector in Jilin, with Dongliao County as a core producing area. Seed quality is critical for autumn harvests. This year's abnormal climate, with heavy early rainfall and a typhoon-induced new round of precipitation, has added challenges. The expert team, led by chief expert Liu Baoyu, included several post specialists and test station heads, reflecting the system's emphasis on grassroots technical implementation.
Core Technical Guidance
The team visited Dongliao Fengguo Breeding Cooperative, Dongliao Zhongcheng Tussah Breeding Cooperative, and Dongliao Liaoheyuan Sino-German Modern Agriculture Co., Ltd. Focusing on the start of bivoltine tussah autumn seed production, they stressed temperature and humidity control. High humidity increases the risk of unfertilized eggs, so enterprises were urged to enhance environmental regulation and ensure safety. This guidance underscores that standardized operations are key to maintaining production amid climate volatility.
Industry Impact
This technical guidance is not an isolated event but reflects the industry system's ongoing efforts to promote standardized farming. The Dongliao Comprehensive Test Station has completed its set tasks, with the next step focusing on autumn silkworm demonstrations. For buyers, improved seed quality means more stable silk quality; for farmers, it reduces yield loss risks from abnormal weather. From an industry perspective, the technology system is narrowing the gap between research and field application.
