Embodiment 1
[0030] A kind of potato high ridge concave ditch secondary covering soil sun-shading drought-resistant high-yield cultivation method, the specific steps are:
[0031] 1) Soil selection and preparation: choose sandy or loamy soil with convenient irrigation and drainage and deep soil layer. The previous crops are not solanaceous crops, preferably gramineous crops. After the previous crops are harvested, deep plowing should be carried out. -30㎝, the soil is flat, finely crushed, and free of rubbish;
[0032] 2) Seed potato treatment: select high-quality virus-free seed potatoes, remove rotten and damaged unqualified seed potatoes 15-20 days before sowing, rinse them with clean water, and soak them in a 600-fold dilution of carbendazim and metalaxyl mancozeb After 15-20 minutes, pick up and drain and put it on the clean ground outdoors to dry, then spray the seed potatoes evenly with deltamethrin solution (prepared with 2.5% deltamethrin mixed with 2500 times water), and again Af...
