First, the hanging storage method When harvesting garlic, we must strictly select the garlic that is hanging and stored, and those garlic that is too small, rotten, damaged and damp should be removed. Then spread it on the ground to dry until the stems and leaves become soft and yellow, and the garlic skin is dry. Finally, 50- 100 pieces of garlic with the same size were woven and hung under a cool, ventilated and rainproof eaves to dry and preserve.
Second, after the garlic is harvested, remove the scattered, moth-eaten, moldy and injured garlic to avoid getting wet and rotting. A week or so, and then the second yard. Repeat this twice to dry all garlic, then transfer it to a ventilated place indoors, pile it in a storage room or bamboo basket, keep it in a low humidity and cool condition, and check it frequently.
3. The width of buried ditch by burying method is1~1.5m.. After garlic is buried, it can't be checked at any time. In order to avoid decay and loss during storage, garlic without disease and damage should be strictly selected for storage before burial. Generally, chaff is used as a covering for garlic burial. First, lay a layer of 2 cm thick chaff on the bottom of the ditch, and then pile up chaff layer by layer until it is about 5 cm above the ground to prevent garlic from being exposed to the air. It creates a certain sealing condition, inhibits the respiration of garlic, reduces the oxygen content, is conducive to the deposition of carbon dioxide in the storage environment, and provides good conditions for garlic storage.
4. Radiation storage Radiation treatment is to irradiate garlic with lethal dose of R-ray 14000 roentgen. When irradiated, water and other substances in garlic will be ionized by R-rays passing through bulbs, producing free radicals or ions, thus inhibiting metabolism. The method has simple operation and high fresh-keeping quality, and can be stored at room temperature for about 1-2 years.
5. Chemicals commonly used in chemical treatment and storage are chemicals with fresh elements, whose sodium, potassium and ammonium salts are easily soluble in water and have low toxicity to people and animals. The method is: bolting garlic until one week before harvest, adding 120 to 180 times of water to dilute and spraying on garlic leaves to inhibit garlic germination. The sprayer for spraying medicine should be cleaned after use, and be careful not to spray garlic seeds, so as not to affect germination.
