First, the preservation of mushrooms 1. Kinetin preservation method. Use 0.01% 6-aminopurine solution to soak fresh mushrooms for 10 to 15 minutes, remove and drain and store. 2. Sodium metabisulfite treatment. First use 0.01% sodium metabisulfite aqueous solution to rinse the mushrooms for 3-5 minutes and then soak in 0.1% sodium metabisulfite for half an hour, remove, drain, and store in a plastic bag. The fresh-keeping effect is better at room temperature 10-15°C. Second, the lotus root storage method 1. Film account method: The plastic film storage account will be used to cover the lotus root, but should not be sealed, and the account should be transparent once a day. Third, 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. Soil burial method: first use brick or wood to form a burying pit, then a layer of lotus root a layer of soil, heap 5-6 layers, and then cover 10 cm of fine soil. 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. If it is buried in a concrete warehouse, the bottom of the pit shall be first padded with a wooden board or a bamboo frame, and the bottom shall be disinfected with drugs. Then, a layer of fine soil about 10 cm thick shall be laid and stored in the same way as above. If it is buried in open air, it should be selected where the terrain is high and backs against the sun. The layers of soil and earthworms are piled up into slopes or pagodas.
2. Modified atmosphere method. 1 Rapid oxygen reduction method: After the garlic is piled up and sealed with a plastic account, the oxygen is continuously pumped with nitrogen for 3 to 4 times to reduce the oxygen content in the account to 1-3%, and the oxygen content in the account is kept during storage. At 3%, carbon dioxide is about 10%. 2 Natural oxygen reduction method: After the garlic seedlings are credited, 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 2.4%. After the daily measurement, 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.
