Abstract

The invention relates to an annual supply method for fresh-eating sweet potato root tubers. The method comprises the steps that according to the climate characteristics of northern potato areas, biological characteristics of sweet potatoes, storage characteristics of the sweet potato root tubers and the like, a region of which the soil fertility is medium and the texture is sandy loam is selected, the region is divided into a solar greenhouse area, a medium arched shed area, a mulching film covering area, a spring potato area and an autumn potato area; the methods that the mode that the sweet potato root tubers directly come into the market after harvesting and the mode that the sweet potato root tubers come into the market after being stored are combined, open field production and protection ground production are combined, and open field spring potato production and summer potato production are combined are adopted, and the fresh fresh-eating sweet potato root tubers can be provided for the market all the year round. Accordingly, the market vacancy of the fresh-eating sweet potato root tubers from early June to mid-September of each year is filled in, and the requirements of consumers for the fresh-eating sweet potato root tubers all the year round are met; the economic benefit is significantly increased, and the economic income of wide potato farmers is increased.
