The potato is a kind of food and material used in northern China, and the edible part is a large underground tuber. In the north, it has a wide cultivation area, large yield, and is resistant to storage and transportation. It is a vegetable variety that regulates the market surplus. Therefore, there are a large number of potato harvested in winter, which is used to adjust the winter and spring market. However, the storage forms vary from place to place. The vast rural areas in Shanxi use small wells and kiln storage; the northeastern part adopts ditch and the north uses shed storage; the urban commercial system mostly uses large-scale ventilated storage.
First, the potato is improperly stacked, too thick, and the germination and decay caused by the increase of the temperature inside the heap; Second, the temperature rises in the later stage of storage (after the spring). The content of potato starch after germination decreased, the quality was greatly reduced, and a large amount of solanine strontium was formed in the bud eye. When the content of solanine strontium exceeded 0.02%, it could cause different degrees of human and animal poisoning.
The potato germinates during storage because it is a metamorphic tuber with many buds on the stem. The potato has a distinct physiological dormancy after harvest, usually 2 to 4 months. During this period, even if the external conditions are appropriate, the buds of the potato will not sprout. However, when the physiological dormancy period is over, if the temperature and humidity conditions are appropriate, sprouts will grow from the buds. If the outside conditions are not suitable, the potato can continue to dormant without germinating, which is the forced dormancy period of the potato. It determines the length of the potato storage period. The main measures to prolong the forced dormancy period are: control the temperature of the storage environment; use bud suppression preservative to inhibit germination.
The suitable temperature for storage of potatoes is 2.5-4.5 ° C, and the relative humidity of the environment is 80%-85%. Most of the storage facilities we currently use are not able to effectively control the temperature of the storage environment. When winter comes to spring, as the outside temperature rises, the temperature of the storage site begins to increase gradually, leading to the sprouting of the potato. Potato bud preservatives can make up for the lack of facilities, and in the case of warming up, it can still inhibit potato germination.
The use of potato bud preservatives is very simple. After 15 days of potato harvest (after the callus), it can be applied until the budding, but it works best during physiological dormancy. 400 to 800 grams of inhibitor can handle 1000 kilograms of potatoes. When using, spread the germination agent directly on the potatoes in baskets, boxes, net bags or directly on the ground. Then cover the potatoes for 2 to 4 days, then remove the cover.
Because of the convenient, high-efficiency and low-cost use of potato bud-preserving preservatives, it plays a huge role in the reduction and increase efficiency of potato storage process, so it is receiving more and more attention and attention in actual production.
