Choose a warehouse with good ventilation and dry site, first fumigate and disinfect with mixed formalin and potassium permanganate, then put potatoes into the warehouse, generally 750 kg per square meter, about 1.5 m high, surrounded by crates, baskets or wooden boards, and put several bamboo ventilators in the middle. This method is suitable for short-term storage and storage of autumn potatoes.

2, ventilation storage.

Stack potatoes in baskets in the bed, each basket is about 25 kilograms, and the stacking height is 5-6 baskets. In addition, it can be scattered in the bed, with a pile height of 1.3- 1.7 meters, and a space of at least 60-80 cm should be left between the potato pile and the top of the library. Put a ventilation tube every 2-3 meters in the potato pile, or set a ventilation duct at the bottom of the potato pile to connect with the ventilation tube, and blow cold air with a blower. In autumn and early winter, open the ventilation system at night to let cold air in, and close it during the day to prevent hot air from entering. Pay attention to heat preservation in winter and heat it up if necessary. After the temperature rises in spring, the method of short-term outdoor air at night and closing during the day is adopted to alleviate the temperature rise of the reservoir.

3. Drug storage.

Treatment with drugs such as Qingxian element (MH) or methyl tea acetate during storage can inhibit or reduce germination, inhibit the reproduction of pathogenic microorganisms and prevent corrosion. The method is: 98% sodium acetate: acetone: fine soil: potato = 1:2: 100:3300. Take 500 kilograms of potato chips as an example, 98% methyl tea acetate 1.5 grams is needed, which is dissolved in 30 grams of acetone or alcohol, and then slowly mixed into1-1.25 kilograms of dry fine soil, quickly and fully mixed, put into gauze or burlap bags, and then spread the medicine evenly on 500 kilograms of potato chips.

During storage,1-2 layers of fine paperboard can be covered around. The drug is volatilized in a relatively closed environment. The time of drug treatment is about 2 months after harvest (that is, in the dormant period). Otherwise, potatoes that germinate after dormancy, even if treated with drugs, still cannot inhibit germination.
