How to preserve garlic moss in cold storage

The preservation of garlic moss should start from the collection and purchase of garlic moss, and should be controlled and managed from three aspects: temperature, humidity and mildew prevention after preservation. 1, temperature and humidity balanced control. When the storage environment temperature reaches the freezing point of garlic moss, the preservation effect is the best, and the freezing point temperature of garlic moss is -0.8-0℃ (because its solid content is slightly different). In practice, garlic moss will not freeze when the temperature is higher than-1℃. Based on years of experience, it is suggested that the storage temperature of garlic moss should be-65438 0-0℃, and the upper limit temperature control index should be lowered as much as possible within this range to reduce the temperature difference and keep the storage temperature in a stable state. 2. The humidity of the warehouse should be controlled at 80%-90%. If the humidity is not enough, it should be supplemented. Measures mainly include sprinkling water on the ground, hanging wet curtains or spreading sawdust. At the same time, high humidity is also beneficial to the stability of warehouse temperature. 3. Anti-mildew treatment. Specific methods: First, seal the warehouse, and according to the warehouse volume, use 7-9g of medicine per cubic meter. When the garlic moss is precooled to -0.8℃, put the smoke agent evenly in the middle passage of the warehouse and pile it up, then turn off the fan, ignite the pile from the inside out with dark fire, seal the warehouse for more than 4 hours, then turn on the fan, bag and tie the garlic moss tightly, and enter the normal management.
