Scientific storage of potatoes

The stacking method selects a well-ventilated warehouse with a dry site, first fumigated with formalin and potassium permanganate, and then put potatoes into the warehouse, generally 750 kilograms per square meter, about 1.5 meters high, surrounded by crates, baskets or planks. Put a number of bamboo ventilators in the middle. This method is suitable for short-term storage and autumn potato storage.

Ventilation storage method will be stacked potatoes in baskets, each basket of about 25 kilograms, stack height of 5 to 6 baskets is appropriate. In addition, it can also be scattered in the storehouse, with a height of 1.3 to 1.7 meters, leaving at least 60 to 80 centimeters of space between the potato pile and the top of the reservoir. Put a ventilator every 2 to 3 meters in the potato pile, and a ventilation duct can be set up at the bottom of the potato pile to connect with the ventilator and blow into the cold air with a blower. In autumn and early winter, turn on the ventilation system at night to let cold air in, but close it during the day to prevent hot air from entering. Pay attention to heat preservation in winter and heat up if necessary. After the temperature picks up in spring, the method of releasing air for a short time at night and closing during the day is adopted to ease the rise of reservoir temperature.

The application of MH or methyl naphthyl acetate in drug storage can not only inhibit or reduce germination, but also inhibit the reproduction of pathogenic microorganisms and preservative.

The time of drug treatment is about two months after harvest (that is, in the dormant period). Otherwise, potatoes that begin to sprout after the dormant period can not be inhibited even if they are treated with drugs.
