Method for promoting germination of corydalis saxicola bunting seeds

Abstract

The invention discloses a method for promoting germination of corydalis saxicola bunting seeds. According to the method, wild corydalis saxicola bunting seeds which are harvested in May to June every year are wet-stored for 2-6 weeks at low temperature before being cultured, so that the corydalis saxicola bunting seeds are effectively awakened from the dormant state to promote germination; by controlling the culture temperature to be low temperature about 15 DEG C and by performing illumination and shielding culture alternatively, a natural growing environment of corydalis saxicola bunting is effectively simulated, and the germination rate of the corydalis saxicola bunting seeds is increased. In addition, by taking a nutrient solution containing micron-order limestone grains which are obtained from growing places of the wild corydalis saxicola bunting and multiple inorganic salts as a culture medium, the germination rate is increased. By adopting the method for promoting the germination of the corydalis saxicola bunting seeds, the germination rate of the corydalis saxicola bunting seeds is increased to be over 35 percent.

Description

Technical field [0001] The invention relates to the technical field of Coptis scoparia cultivation, in particular to a method for improving the germination of Coptis scoparia seeds. Background technique [0002] Coptis is a perennial herb of the Papaveraceae family. It is born in the crevices of rocks at an altitude of 1200 to 1800 m, especially in the karst caves with extremely high humidity. It is distributed in Gansu, Hubei, Guangxi, Sichuan, Guizhou, Yunnan and other places. [0003] Siberian cylindrica has the effects of clearing heat, detoxifying, dispelling dampness, relieving pain and stopping bleeding. It has been found to have special effects on liver diseases. It is widely used in the treatment of hepatitis, cirrhosis, and liver cancer, and has achieved unexpected miraculous effects, so it is used in hepatitis Liver cirrhosis is handy, applied to liver cancer, and has also achieved the effect of improving the quality of life and prolonging life. [0004] At present, Scute...

Problems solved by technology

[0004] At present, Yanhuanglian is mainly wild, and because of its special geographical location, it generally only grows in the middle of the rocks, not at the top of the mountain or at the foot of the mountain, which makes it difficult to pick and makes the supply rare.

Although the artificial planting has been successfully carried out, due to the low germination rate, the general seed germination rate is less than 10%, resulting in extremely low yields of rock berthia, in short supply, and the price has risen to nearly 1,000 yuan per kilogram. Germination rate is the key factor to improve the yield of Litectin chinensis artificial planting
