1. Storage of Chinese herbal medicines must be stored separately from other trees, vegetables, grains, and grasses to avoid mixing. Before storage, all weeds and dirt must be thoroughly removed. Storage rooms should be routinely sterilized to prevent contamination of drug types.
2, control the moisture. The seed oil containing many oily herbs should be controlled at 8%-9%, and the general seed moisture should be controlled at 12%-13%, because the seeds are susceptible to mildew because of high water content.
3. The optimum environment temperature for storage of seeds of Chinese herbal medicines should be controlled at about 10°C. When the temperature is too high, the seeds will be able to breathe vigorously and will consume their own stored nutrition and reduce the germination rate.
4. Use bricks and wood to increase the height and store seeds of traditional Chinese medicines more than 50 centimeters above the ground. Do not directly put Chinese medicine seeds on the ground to prevent them from affecting the germination rate. Storage room should pay attention to ventilation.
5, do not use plastic bags to seal the seeds of Chinese herbal medicines. Because the plastic is impermeable to air, the seeds are forced to undergo anaerobic respiration, and toxic substances such as alcohol and organic acids are produced and the germination rate is lost.
6. Do not store seeds of Chinese herbal medicines together with pesticides and chemical fertilizers, and do not be fumigated by smoke.
In addition to conventional methods for storage of Chinese herbal medicine seeds, farmers should master the following aspects of storage techniques to ensure their germination rate and prepare for the next season.
