AI Technical Summary
Existing technologies have not yet developed a complete set of integrated methods for breeding high-quality industrial hemp varieties suitable for the soda saline-alkali land in Northeast China, which makes it difficult to meet the needs of efficient development of saline-alkali land and the improvement of quality and efficiency of the industrial hemp industry.
It adopts integrated technologies such as seed salt resistance enhancement, soil improvement, ridge cultivation for salt avoidance, precise water and fertilizer regulation, and green breeding and purity preservation, including soil improvement, seed pretreatment, sowing and ridge cultivation, field management and harvesting and storage steps, to improve seed germination rate and seedling survival rate.
It significantly improves the germination and survival rates of industrial hemp, realizes the integration of stable cultivation and high-quality seed propagation in saline-alkali land, has a high propagation coefficient and excellent germplasm purity, and is suitable for large-scale promotion.
