Abstract:

In the traditional sweetpotato production areas of northern Jiangsu, there are problems such as excessive reliance on the starch processing industry and insufficient development of new fields and new business forms. However, the fresh sweetpotato industry, as a new growth point, faces industrial technical bottlenecks such as rough cultivation and management, water and fertilizer resources waste, low yield and poor quality. Therefore, this experiment conducted study on key technologies such as high-ridge dense planting, reduced fertilizer and pesticide use, integrated water and fertilizer management, and mechanical harvesting for high-quality fresh sweetpotato varieties. It clarified the technical parameters of key links, established an efficient cultivation model centered on “high-ridge dense planting” and “integrated water and fertilizer management”, and integrated and optimized a full-chain technical system including variety screening, efficient cultivation, mechanized operation, and scientific storage, with the aim of providing a systematic solution to the common problems of “coarse planting, poor growth and difficult harvest” in the fresh sweetpotato industry in northern Jiangsu, and strongly supporting the adjustment of the regional sweetpotato industry structure and the increase of farmers' production and income.

Key words: northern Jiangsu, fresh-eating sweetpotato, high-efficiency cultivation, industrial technology
