Research on solutions for developing mulberry cultivation and sericulture associated with value chain production

(QNO) - On June 12, the Department of Science and Technology accepted the project "Research on synchronous solutions to develop mulberry cultivation and sericulture associated with value chain production in Quang Nam province". The project was chaired by MSc. Le Xuan Anh, Institute of Soil and Fertilizer (Vietnam Academy of Agricultural Sciences).

MSc. Le Xuan Anh and his colleagues have identified suitable areas for developing mulberry cultivation and silkworm breeding in Quang Nam; selected high-yielding mulberry and silkworm varieties suitable for the ecological and seasonal conditions of Quang Nam; developed highly effective mulberry cultivation and silkworm breeding processes; and built a highly effective mulberry cultivation and silkworm breeding model according to the value chain.

According to the 2019 survey results, the total area of mulberry cultivation land for silkworm raising in Quang Nam localities is 18 hectares. Of which, Dien Ban has 4 hectares planted in Dien Quang commune; Duy Xuyen has 12 hectares, including 5 hectares in Duy Trinh commune and 7 hectares in Duy Chau commune; Nong Son develops 2 hectares in Que Trung commune.

By 2022, the mulberry area of localities will increase significantly. Of which, Duy Xuyen alone has about 50 hectares distributed in Nam Phuoc town and Duy Trinh, Duy Chau, Duy Hoa communes; Dien Ban has more than 5 hectares concentrated in Dien Quang commune; Dai Loc has about 7 hectares.

In the 4 districts and towns mentioned above, there are more than 200 agricultural production households with a history of developing the mulberry growing and silkworm raising profession.

The research team took soil samples to analyze and evaluate the physical and chemical properties of the soil and the quality of the research area. The results showed that the land for developing mulberry cultivation belongs to 3 soil groups: alluvial soil, gray soil, sandy soil and related factors.

Thereby, proposing priority areas for mulberry cultivation development in 4 districts and towns in the period of 2020 - 2025 with a total area of 4,663.9 hectares (Duy Xuyen 810 hectares, Dien Ban 1,614.4 hectares, Nong Son 497.2 hectares, Dai Loc 1,741.7 hectares) and proposing priority areas for transitional development in the period of 2025 - 2030 in districts and towns is 3,434.8 hectares.

The research team also selected 3 effective intensively grown strawberry varieties in Quang Nam, namely VH15, GQ2 and S7CB, planted at a density of 50 thousand trees/ha, giving a second-year leaf yield of 34.39 - 36.85 tons/ha.

Determining the appropriate silkworm breeding structure in Dien Quang commune, in the spring and autumn seasons, raise 3 hybrid silkworm breeds of white cocoons GQ1235, LD09, LQ2 with a yield of 18 - 21 kg of cocoons/egg cycle; in the summer season, raise the hybrid multi-system silkworm breed of yellow cocoons VNT1 with a yield of 18.8 kg of cocoons/egg cycle.

The project organized 3 technical training sessions on high-efficiency mulberry cultivation and sericulture and 3 field trip conferences in localities with 180 participants.

Scientists made recommendations on scientific and technological solutions such as building projects to expand the scale and develop industry for research localities; building technical documents to widely disseminate to localities developing mulberry cultivation and sericulture in the province.

It is recommended that localities have a plan for mulberry growing and sericulture areas in the short, medium and long term for each locality and specific period. The Department of Agriculture and Rural Development builds a project to develop a synchronous expansion of mulberry growing and sericulture in localities with methods such as investing in building short-term and long-term programs.

Specifically, support households growing mulberry and raising silkworms in terms of mulberry and silkworm varieties; support households raising concentrated crops and assign them to agricultural cooperatives to manage and direct production; have policies to encourage businesses to cooperate with cooperatives to purchase output for cocoon products for production households.

Build silkworm nurseries to reduce the cost of transporting cocoons to other localities; establish a local silkworm seed distribution facility; develop a "silk river" project combining mulberry cultivation, silkworm breeding, silk reeling and silk weaving with tourism development...
