In addition to conventional storage methods, Chinese herbal medicine farmers should carefully master the following six storage techniques to ensure the germination rate of medicinal herbs. The drug species must be stored separately from other (tree, vegetable, grain, and grass) 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 contamination of the drug species. To control the moisture content, the moisture content of the drug species containing more oil should be controlled at 8% to 9%, and the general seed content should be controlled at 12% to 13%. Excessive moisture, easy to mold. The optimum temperature of the drug species should be controlled at about 10°C. If the temperature is too high, the seeds will be able to breathe vigorously and will consume their own nutrition and reduce the germination rate. The use of bricks and mortars for medicinal herbs shall be conducted with a height of 50cm above the ground, and they shall not be placed directly on the ground, otherwise they may be easily damped to reduce the germination rate. The drug species must not be sealed with plastic bags. Because the plastic bag is airtight, the seeds are forced to undergo anaerobic respiration, which produces toxic substances such as alcohol and organic acids, and loses germination power. The drug types must not be stored together with pesticides and chemical fertilizers. They must not be smoked by smoke, but they must also be protected from rat and insect bite.
