Embodiment Construction

[0025] The present invention is further described below through examples, but the protection scheme of the present invention is not limited to the following examples.

[0026] 1. Seed selection: Choose processed varieties, especially those with high pigmentation, good disease resistance, and high drying rate.

[0027] 2. Seedling cultivation: Choose potato pieces without scars and disease spots as medium seed potatoes, and pretreat them with 70% thiophanate-methyl 1,000 times solution at a temperature of 50°C or 25% carbendazim 500 times solution for about 5 minutes. Finally, plant seedlings on the greenhouse seedbed. The seedbed is 1.2m wide and 20-30cm deep. , the head is slightly higher, the tail is covered with mud, and the direction of the head and tail is the same. Then apply 10 dan of decomposed fertilizer per mu, evenly cover the seed potatoes, cover with 1.5-2cm fine soil, then cover with plastic film, and compact the surrounding area with fine soil; After emergence,...
