In addition to conventional storage methods, Chinese herbal medicine farmers should carefully master the following six storage techniques to ensure the germination rate and make preparations for the next season. 1. The drug species must be stored separately from other vegetables, grains, grass, and tree seeds to avoid mixing. Before storage, the stems, leaves, weeds, soil and other debris should be thoroughly removed. The storage room should be routinely disinfected to prevent the seeds from being contaminated. 2. Control the moisture content. Seed moisture of herbs containing more oil should be controlled at 8%-9%, and general seeds should be controlled at 12%-13%. Excessive moisture, easy to mold. 3. The optimum temperature for storage of medicinal herbs should be controlled at 10°C. If the temperature is too high, the seeds will be vigorously consuming their own stored nutrients and reduce the germination rate. 4. Seed and packaging bricks should be applied with a height of 50cm above the ground. Do not place them directly on the ground. If they are easily damp, the germination rate will be reduced. The storage room should be ventilated and ventilated. 5. The seeds must not be sealed in plastic bags. Because the plastic bags are airtight, the seeds are forced to undergo anaerobic respiration. They will produce toxic substances such as alcohol and organic acids and they will die and lose their germination power. 6. Seeds should not be stored together with pesticides and chemical fertilizers and must not be smoked by smoke. Take care to prevent rat damage, insect bites, etc.
