Storage of soil, should be fine with a soft hand to squeeze the group is not suitable for the group, storage, the oyster should be discharged in order, so as not to break.

Second, the storage and preservation of garlic
1. Refrigeration method. After fully precooling the garlic, it is put into a basket or a crates, or directly stacked on a storage shelf, so that the temperature is controlled at about 1°C.
2. Atmosphere adjustment method. 1 Rapid Oxygen Reduction: After the garlic is piled up and sealed with a plastic account, it is continuously pumped oxygen for 3 to 4 times to reduce the amount of oxygen in the account to 1 to 3%. During the storage process, the amount of oxygen contained in the account is reduced. At 3%, carbon dioxide is about 10%. 2 Natural oxygen reduction method: After the garlic seedlings are brought into account, the plastic account is immediately sealed. The oxygen in the account is absorbed by the garlic seedlings, so that the oxygen partial pressure gradually drops to 2 to 4%; after the daily adjustment, the oxygen partial pressure is maintained at the site. Needed range. 3 Fill carbon dioxide method: After the garlic seedlings are piled up and sealed with a plastic account, a small amount of gas is sucked out of the account so that the content of oxygen and carbon dioxide in the account is basically the same. As the oxygen content in the account falls, slaked lime is used to absorb the carbon dioxide and cause it to decline accordingly. After the oxygen content should be controlled at 1 ~ 3%, carbon dioxide 10%, temperature 14 ~ 16 °C.
