For storage of onions to choose yellow, flat round, low moisture content, spicy taste, fine bulb neck is appropriate. The storage of onions is best when the lowest 1--2 leaves are dry and the ground starts to fall. After harvesting, dry the onions and arrange the onions diagonally so that each row of stems and leaves is just covered with the onion on the front row to prevent the onions from being directly exposed to sunlight. Turn it on for 2 to 3 days and keep it until the leaves turn yellow. Take 4-6 days. The onion leaves were then braided to a length of about 1 meter, and the two “dumplings†were tied together, each of which was about 60 onions. The onion that has been prepared is still required to be air-dried for 5 - 6 days, and dried until the onion is fully dried. It is advisable that the onion be completely turned into a cortex. During onion drying, it is difficult for the onions to dry, and it is easy to rot. Therefore, care should be taken to avoid rain during drying. The treated onion should be stored immediately, usually hanging under the eaves or indoors. Hanging rooms require good ventilation and are kept dry. Stacking method is also available, that is, in high-lying, well-drained areas, with straw or wheat straw mats, then two layers of mats, and then the onion is hung up to 1.5 meters, the top cover 3--4 layers Banquets are surrounded by feasts; they are tied tightly with ropes to prevent direct sunlight or rain from seeping through. Onion leaves can also be removed and stored on the shelf. Note that the onions are perishable during the early storage period, so they should be kept dry in the early stage; the onions are easily sprouted in the late period of storage, and the onion can be sprayed with 0.25% fresh solution before the harvest, which can inhibit the sprouting and can also be harvested after the onion is harvested. Dip root with 0.25% fresh beef.
