Super-high-yield cultivation method for Dazuchun potatoes

The invention belongs to the technical field of crop cultivation, and discloses a super-high-yield cultivation method for Dauchun potatoes, which comprises the following steps: selecting a late-maturing variety with late blight resistance, high yield and stable yield; carefully selecting seed potatoes for sowing, timely early sowing and rational close planting; early-stage seedling lifting is achieved through technologies such as under-film drip irrigation and on-film soil covering; water and fertilizer integration and slow-control fertilization; late blight is prevented and controlled by combining a late blight monitoring and early warning system; the photosynthesis of plants is promoted by cutting stems and pruning branches, controlling the plant height, erecting a frame and supporting vines, preventing lodging, improving the field ventilation and light transmission conditions. The problems of low-temperature drought in the early stage, slow plant growth, field closure in the later stage, serious late bligh
