The application of microbial agents on mulberry leaves utilized for feed silkworms has resulted in significant improvements in the physical condition and survival rates of the newly bred silkworms. There has been an increase of 13 percent to 15 percent in cocoon production.

In recent years, Hechi has witnessed a widespread adoption of microbial breeding technologies, which has improved their resistance to bacterial diseases and other illnesses, consequently leading to a consistent upsurge in cocoon production.

By the end of May, the city's cocoon production surged to 65,300 metric tons, marking a year-on-year increase of 31.41 percent. Moreover, cocoon purchase prices have reached historic highs.

In 2022, Hechi has achieved a 10 percent to 30 percent increase in mulberry leaf production per acre through the deployment of microbial agent spraying, application of organic fertilizers, and implementation of low-yield transformation in mulberry orchards. Currently, new technologies such as microbial breeding services cover 70 percent of the city's family farms and silkworm farmers.

Through the collaborative efforts of technical teams and a profound understanding of Hechi's soil, climate, and other practical conditions, specialized microbial formula tailored to the local climate and soil has been developed after more than four years of experimentation.

Increasing numbers of villagers are now adopting these innovative technologies, as witnessed by the rise in the number of silkworm farmers in Tangjiang village from 69 to 90 households This phenomenon has propelled a bountiful harvest of both quantity and quality of cocoons throughout the village.
