Potato plastic film covering cultivation: After covering the plastic film, not only can keep the soil humus moist, saving water, but also can increase soil temperature and promote the growth and development of potatoes. According to the experiment, potato tubers grown in plastic mulching film swell early and grow fast, which can not only shorten the growth period, raise the morning market, but also increase the commodity rate of the tubers. Specific approach: take a wide ridge double row cultivation, ridge width of 1.5 meters, double row staggered sowing, timely covering the film after sowing, film seedling emergence after emergence, to prevent the temperature is too high and burn seedlings.
Cultivation of potatoes in the arms: Cultivation of potatoes in the nest is to use the apical dominance of the potatoes. Seedlings are grown with small whole potatoes and then transplanted, or the shoots are first grown with large shoots (short and stout shoots) and sown (deeply planted, lightly covered). Soil), watering and soiling several times after emergence, and appropriately delaying the harvest period. Using this cultivation method can greatly increase the number of stems and tubers of the plant, thereby increasing the yield.
