Jilin Province's tussah industry chain is facing a critical technical window. From July 13 to 14, a team led by Chief Expert Liu Baoyu of the province's tussah industry technology system conducted intensive field visits to three demonstration enterprises in Dongliao County, Liaoyuan City, providing on-site technical guidance for autumn breeding. Behind this move is the direct pressure of abnormal climate on tussah breeding this year—excessive early rainfall, compounded by new rains from typhoon impacts, making temperature and humidity control the core variable for breeding success.
Background
Dongliao County is a key area for tussah farming in Jilin Province. The three demonstration enterprises visited—Fengguo Breeding Cooperative, Zhongcheng Tussah Breeding Cooperative, and Liaoheyuan Sino-German Modern Agriculture Co., Ltd.—all undertake demonstration tasks within the industrial technology system. The autumn breeding of bivoltine tussah has just started. The expert team inspected the construction and promotion status of demonstration bases and provided targeted recommendations on temperature and humidity management during the breeding process.
From a technical perspective, the team emphasized that under current climatic conditions, the occurrence of unfertilized eggs must be prevented. Unfertilized eggs indicate substandard seed quality, directly affecting the hatch rate and survival rate of silkworm larvae in the following year. For farmers, this means not only yield loss but also sunk costs. Therefore, the team's guidance focused not only on technical parameters but also on production safety—ensuring seed quality while preventing large-scale disease outbreaks caused by environmental loss of control.
Industry Impact
The essence of this technical guidance is the precise delivery of industrial technology systems to the grassroots level. The Dongliao Comprehensive Test Station of the tussah industry technology system has completed its scheduled phased tasks, and the next step is the critical autumn silkworm demonstration period. For buyers and processing enterprises, the quality of autumn silkworm seeds directly determines the yield and quality of subsequent cocoons, thereby affecting the supply stability of end products such as tussah silk and tussah fabric.
From an industry-wide perspective, the scale and standardization of tussah farming in Jilin Province are still in the process of improvement. The deployment of expert teams means that technical resources are accelerating their flow from laboratories to fields. For demonstration enterprises, this guidance not only solves current breeding problems but also establishes a replicable quality control process—from temperature and humidity control to pest and disease prevention, to production safety norms. These experiences will benefit more small and medium-sized farmers in subsequent promotions.
It is worth noting that typhoons and rainy weather are not isolated incidents. In recent years, extreme climates have become frequent, posing a continuous threat to farming industries such as tussah that rely on natural environments. The industry needs to establish more flexible emergency response mechanisms, such as introducing more precise environmental monitoring equipment during the breeding stage or making partial adjustments to the breeding cycle. The expert team's on-site diagnosis this time actually provides a practical sample for the industry to deal with climate anomalies.
