Key Techniques for Potato Cultivation with Plastic Film Mulching

Potato Cultivation with Plastic Film Mulching After mulching with plastic film, not only can the soil ridge surface remain moist, saving water, but the soil temperature can also be raised, promoting the growth and development of potatoes. According to experiments, potatoes cultivated with plastic film mulching have tubers that swell early and grow quickly, which can not only shorten the growth period and bring them to market earlier, but also increase the marketable rate of the tubers. Specific method: adopt wide-ridge double-row cultivation, with a ridge width of 1.5 m, sow in double rows with staggered hills, cover with plastic film promptly after sowing, and after emergence, break the film to let the seedlings out, preventing excessively high temperatures from burning the seedlings.
