1. After the potato mulch film is covered with the cultivation mulch, it will not only keep the ridge of the soil moist, save water, but also increase the soil temperature and promote the growth and development of the potato. According to the experiment, potato tubers grown in film-covered cultures swell early and grow faster, which can not only shorten the growth period, raise the 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. 2. Cultivation of Potato Waffle Potato Waffle Cultivation is the use of potato apical dominance to grow seedlings with small whole potatoes and then transplanting them, or first to grow large shoots (short and stout shoots) from the tubers, then sowing (deep planting, shallow Cover soil), watering and soiling several times after emergence, and appropriately postponed the harvesting period. Using this cultivation method can greatly increase the number of stems and tubers of the plant, thereby increasing the yield.
