Plastic film potato planting is troublesome, and it is suitable for places with less land and more people, and the planting area is not too large. If potatoes are planted in spring, it is best to cultivate the land deeply in the winter of the previous year, because potatoes like loose soil, and potatoes themselves have the function of loosening soil.
