When the spring potato just emerged, it was timely to break the membrane and raise the seedlings. It was found that the dead seedlings and the lack of seedlings were supplemented with the ready-to-prepare seedlings. Qimiao after the top dressing balance fertilizer, mu urea 5 kilograms of water to the point of irrigation, potato harvesting urea 5 kilograms, high-concentration compound fertilizer 10 kilograms for large fertilizers. Spring potatoes generally do not require burping, but flower stems must be removed before flowering to concentrate nutrients for tuber enlargement. Always keep the field dry and wet suitable, especially after the potato, the field can not accumulate water, it is necessary to drain the soil in time, otherwise it is easy to cause the rot of the tuber. The main diseases are virus disease, bacterial wilt, and black stem disease. It can be used to prevent virus disease and bacterial wilt by 1:200 times carbendazim soaking and controlling root stem disease with 200~250ppm agricultural streptomycin. For buds with a tendency to grow crops, 15% paclobutrazol is used to spray 50 kg of water on a field plot, and 25 ml of 25 ml of Vintagin is sprayed on water at a flowering stage to make the plants dwarf and promote underground. The enlargement of tubers increases the yield. According to field experiments, after spraying Vitrazine 4, the plant height can be reduced by 7.2 cm, the ratio of large tubers increased by 12.06%, and the yield increased by 9.02%.
