Chinese herbal medicine seed processing technology Planting Chinese herbal medicines is an effective way to develop effective agriculture in mountain areas. In recent years, the area of ​​Chinese herbal medicine planting in the mountains and southwest of Zhejiang has been increasing. In order to improve seed quality, prevent seed diseases and insect pests, break seed dormancy, promote seed germination and robust seedling growth, Chinese herbal seeds are generally treated before sowing. 1, selection. Select seeds that are full, well-developed, uniform in size, do not carry eggs, and have strong viability. When the number of seeds is small, it can be manually selected. When the number is large, water selection or winnowing can be used. 2, drying species. Sowing before sowing can promote the physiological after-ripening of some seeds, promote the internal metabolism of seeds, enhance seed vigor, increase germination potential and germination rate, and can play a role in sterilization. Dry seeds are generally selected sunny weather 2-3 days. When drying on the cement floor, be careful not to spread too thin to prevent burns to the seeds, generally 5 to 10 cm is appropriate. Turn once every 2-3 hours to make the seeds evenly heated. 3, soaking. Direct soaking with cold water or about 40°C warm water or alternate soaking with cold and hot water alternately for 24 hours can soften the seed coat and increase its permeability. It can kill pathogens inside and outside the seed and prevent disease transmission, prompting the seeds to grow quickly and neatly. Germination. It is also possible to apply some chemicals directly to the seed treatment during soaking. (1) According to seed characteristics, select the appropriate chemical agent and treat the seed at the appropriate concentration. Such as Codonopsis seeds are 0.1% baking soda or 0.1% potassium bromide solution immersed for 30 minutes, picked up immediately sowing, general germination can be advanced 10-12 days, the germination rate increased by about 10%. (2) With growth hormone treatment, commonly used hormones are indole acetic acid, gibberellin and so on. If the seeds of Codonopsis pilosicoli were soaked in a 0.005% gibberellin solution for 6 hours, the germination rate increased by 11.5%. (3) Add trace elements to soak in water. The use of boron, zinc, manganese, copper, molybdenum and other trace elements solution soaking, can increase production. If the seeds of Platycodon grandiflorum are soaked in a solution of 0.3-0.5% potassium permanganate for 1 day, the yield of seeds and roots can be increased by 30% and 35% respectively. 4, bruises or broken shell treatment. Some herbal seed coats are hard, rich in wax and impervious to water, affecting the germination of seeds. The testicles are damaged by artificial shelling, rubbing, etc. to increase the permeability and promote germination. Such as Eucommia can be used to cut the samara, remove the seed directly sowing; Astragalus, Andrographis seed coat waxy, can be rubbed with fine sand, and then soaked in warm water after sowing, can significantly increase the germination rate. 5, layered processing. That is a layer of wet sand, a thin layer of seed, then a layer of wet sand, and then spread a thin layer of seed, so repeat the stacking method. This method can break the seed dormancy and promote ripening and germination. Such as peony, honeysuckle, berberine, ginkgo and other seeds commonly used stratification treatment to promote germination. 6, dressing. Each 500 grams of seed plus 3-4 grams of 50% carbendazim and other chemicals seed dressing, can kill the seed surface and soil. The germs in the soil prevent disease such as seedling damping-off. In addition, the use of bacterial fertilizer seed dressing, can increase the beneficial microorganisms in the soil, the soil and air can not directly use the elements of the plant into the plant can absorb the nutrients, thus promoting the growth and development of Chinese herbal medicine, commonly used fungus fertilizer Rhizobium agent, Nitrogen-fixing agents, etc. In addition to the above commonly used methods, it is also possible to treat seeds with rays and ultrasonic waves to promote germination, vigorous growth, early maturation, and the like.
