Method for increasing germination rate of daphne giraldii nitsche seeds

Abstract

The invention discloses a method for increasing the germination rate of daphne giraldii nitsche seeds, and belongs to the fields of quality determination and cultivation of Chinese medicinal material seeds. The method comprises the following steps: (1) seed pretreatment: peeling daphne giraldii nitsche seeds, soaking the peeled daphne giraldii nitsche seeds into distilled water for 12-36 hours, and removing seeds floating on the water surface while leaving seeds submerged under water to obtain peeled seeds; (2) seed disinfection: soaking the peeled seeds into disinfectant for 10-40 minutes for disinfecting, and flushing with distilled water; (3) seed cultivation: placing the disinfected seeds into a tray loaded with a substrate for cultivating, and watering during cultivating; and (4) germination acceleration: placing the tray in which the seeds are planted into a manual climatic box to accelerate germination. The method for increasing the germination rate of the daphne giraldii nitsche seeds is simple, convenient and practicable, and has high repeatability, a good effect and high working efficiency. By using the method, the mildewing rate of the daphne giraldii nitsche seeds can be lowered, and the germination rate of the daphne giraldii nitsche seeds is increased effectively. The mildewing rate of the daphne giraldii nitsche seeds is 16.23 percent, and the germination rate is 83.77 percent.

Description

technical field [0001] The invention belongs to the field of quality identification and cultivation of Chinese medicinal material seeds, in particular to a method for improving the germination rate of Daphne chrysanthemum seeds. technical background [0002] Daphne giraldii Nitsche (Daphne giraldii Nitsche) belongs to Daphne giraldii Nitsche plant, also known as knotted flower and knotted incense. Distributed in my country's Shaanxi, Gansu, Qinghai, Henan and other provinces, Gansu Province is mainly distributed in Qilian Mountains and other hillside shrubs, forest margins, and valleys at an altitude of 2000-2600m. Daphne chrysogenum can be used as raw material for papermaking. Its root bark and stem bark are commonly used traditional Chinese medicines for treating rheumatism and pain relief. It has anti-tumor activity and strong analgesic effects, and can also be used to treat arthritis, analgesia, anti-inflammation, and surgical anesthesia. The plant Huang Ruixiang is cu...

Problems solved by technology

The plant Huang Ruixiang is currently a wild resource. It is the original plant of the traditional Chinese medicine Zushima. The used parts are the root bark and stem bark. Excessive and unreasonable root digging methods have severely damaged plant resources, resulting in an extreme shortage of Zushima original plants; And because the seeds of Huang Ruixiang have firmness and dormancy, poor water permeability, easy to mold and very low germination rate, the natural seedling rate is not high, it is difficult to meet production needs; In the report "Influence on the Germination of Daphne chrysogenum Seeds of Patriarch Asahara Plant", the germination rate of Daphne chrysogenum seeds is the highest at 20.47%; Seedlings are imminent, and there is no report on the method for improving the germination rate of Daphne chrysanthemum seeds in the prior art, and it is urgent to provide a method for improving the germination rate of Daphne chrysanthemum seeds
