The stacking method is to select well-ventilated and dry-field warehouses. First, formalin and potassium permanganate are used for fumigation and disinfection. Afterwards, the potatoes are put into warehouses. Generally, 750 kilograms are piled per square meter and the height is about 1.5 meters. Crate, basket or wooden board surrounded, put a number of bamboo ventilation tube in the middle. This method is suitable for short-term storage and storage of autumn potatoes. Ventilation store methods pile potatoes in baskets, about 25 kilograms per basket and 5-6 baskets. In addition, it can be piled up in a warehouse, with a height of 1.3-1.7 meters, and at least 60-80 centimeters of space must be left between the potato stack and the top of the warehouse. Put a ventilator every 2-3m in the potato stack, and connect the ventilator to the ventilator at the bottom of the potato stack, and use a blower to blow cold air. In autumn and early winter, the ventilation system is turned on at night to allow cold air to enter, and during the day it is closed to prevent hot air from entering. In winter, attention should be paid to heat preservation and, if necessary, warming. After the spring temperature rises, the nighttime ventilation and daytime closure are used to ease the rise of the temperature. The use of drugs such as mh or methyl naphthylacetate in the storage of drugs can inhibit or reduce the germination, inhibit the proliferation of pathogenic microorganisms, and can prevent corrosion. The time of drug treatment is appropriate around 2 months after harvest (ie during dormancy). Otherwise, potatoes that have germinated after the dormancy period, even if they are treated with drugs, still cannot suppress germination.
