The selection of cultivated areas and the selection of small places are the important conditions for anti-frost and economic and social benefits of precocious cultivation of spring potato. Premature cultivation using the film, 200 meters above sea level agricultural use of higher value, the real morning market. Small locations should choose leeward, sunny, warm, easy drainage of the field, that is, the choice of cold air is not easy to gather or go through the field, can reduce or avoid night hazard.
