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.

The feeding value of using potatoes to feed pigs
1. Nutritional characteristics: high yield of potato, low crude fiber content of tuber (4.4%), high biological potency of protein, and about 80% of dry matter of tuber is starch, which is higher than ordinary crops according to the amount of digestible energy and protein produced per unit area. The energy value is slightly higher than that of sweet potato, but lower than that of corn; the content of crude protein is about 9%, which is higher than that of cassava and sweet potato, the content of lysine is higher than that of corn; the content of carotene is very low, and the content of other vitamins is similar to that of corn. Potatoes contain antitrypsin factor

Variety source: formerly known as Calwhite, alias A76147-2, it was selected from the hybrid offspring of Pioneer × BC8370-4 in the United States. It was approved and approved for promotion by the University of California, the Idaho Experimental Station and the United States Department of Agriculture in 1997. Characteristic plant type erect, strong, green stems and leaves, plant height about 70cm; Corolla is a medium-mature variety, about 8Od from emergence to maturity. The plant has strong resistance to stress and invades internal and external such as growth crack, broken skin, hollow and thermal necrosis.
