Before seeding, the seed potatoes should be treated through seed selection, seed drying, seed soaking and seed cutting. Among these four links, cutting seeds is closely related to mechanical sowing. Before sowing, seeds must be cut according to the standard. The planters of the three planters have the same size. Therefore, it is required that the potato seed be the same size, and prepare a 1500-fold high potassium ferrate solution before cutting. Used for soaking disinfection of cutters and cutting boards. The weight of the seed block is maintained at about 50 grams. The seed potato is large, the bud eyes are few, the seed potato is small, and the bud eyes are many. Each species block leaves 2 to 4 full bud eyes. The size of the cuts should be controlled within 3.5 to 4.5 cm. Seed potatoes should be soaked in a 1000-fold solution of 75% rare earth dryland treasure for 30 minutes. It can not only be bactericidal and antiseptic, but also a plant growth regulator, which can promote the germination and rooting of potato seed potatoes, and can also enhance drought resistance.
