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 Daphne rhizome seeds have firmness and dormancy, the germination rate is very low, and it is difficult to meet the production demand; this will inevitably affect the reproduction of Daphne rhizome plants and the full utilization of the medicinal value of Daphne rhizome plants; there is no relevant breakthrough in the prior art. Report on the method of dormancy of Daphne chrysogenum seeds, it is urgent to provide a method to break the dormancy of Daphne radix seeds

Embodiment 1

[0030] The method for breaking the dormancy of Daphne chrysanthemum seeds comprises the following steps:

[0031] (1) Seed disinfection: soak the tested seeds in 0.2% potassium permanganate solution for 20 minutes for disinfection, and rinse with distilled water;

[0032] (2) Wet storage in the cellar: Mix the seeds obtained in step (1) with wet sand at a volume ratio of 1:3 to form mixed sand seeds, and then stack them in a vegetable cellar for wet storage for 80 days. The stacking thickness is 40cm, the humidity of described wet sand is 60%, the thick wet sand of 12cm is covered above the mixed sand seed of described stacking.

[0033] Measurement results: the germination rate of Daphne chrysanthemum seeds was 30.47%, and the germination potential was 18.12%.

Embodiment 2

[0035] The method for breaking the dormancy of Daphne chrysanthemum seeds comprises the following steps:

[0036] (1) Seed disinfection: soak the tested seeds in 0.2% potassium permanganate solution for 20 minutes for disinfection, and rinse with distilled water;

[0037] (2) Wet storage in the cellar: Mix the seeds obtained in step (1) with wet sand at a volume ratio of 1:3 to form mixed sand seeds, and then stack them in a vegetable cellar for wet storage for 20 days. The stacking thickness is 30cm, the humidity of the wet sand is 50%, and the thick wet sand of 6cm is covered above the mixed sand seeds of the stacking.

[0038] Measurement results: the germination rate of Daphne chrysanthemum seeds was 0%, and the germination potential was 0%.

Embodiment 3

[0040] The method for breaking the dormancy of Daphne chrysanthemum seeds comprises the following steps:

[0041] (1) Seed disinfection: soak the tested seeds in 0.2% potassium permanganate solution for 20 minutes for disinfection, and rinse with distilled water;

[0042] (2) Wet storage in the cellar: Mix the seeds obtained in step (1) with wet sand at a volume ratio of 1:3 to form mixed sand seeds, and then stack them in a vegetable cellar for wet storage for 100 days. The stacking thickness is 50cm, the humidity of the wet sand is 60%, and the thick wet sand of 16cm is covered above the mixed sand seed of described stacking.

[0043] Measurement results: the germination rate of Daphne chrysanthemum seeds was 22.97%, and the germination potential was 16.08%.

Abstract

The invention discloses a method for breaking the dormancy of daphne giraldii seeds, belonging to the field of quality identification and cultivation of traditional Chinese medicine seeds. The method comprises the following steps: (1) disinfecting the seeds, namely soaking and disinfecting seeds to be tested by using a potassium hypermanganate solution; washing cleanly by distilled water; and (2) wetly preserving in a cellar, namely mixing the seeds of the step (1) and wet sand, and stacking into a vegetable cellar in piles for wet storage. The method for breaking the dormancy of the daphne giraldii seeds disclosed by the invention is simple, convenient and feasible and has a reliable principle, good repeatability and good effect; the dormancy of the daphne giraldii seeds can be rapidly broken and the germination rate and the germination potential of the daphne giraldii seeds can be effectively improved; the working efficiency is high and the repeatability is good; the germination rate of the daphne giraldii seeds is up to 30.47% and the germination potential is up to 18.12%.

Description

technical field [0001] The invention belongs to the field of quality identification and cultivation of seeds of traditional Chinese medicinal materials, in particular to a method for breaking dormancy 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. The root bark and stem bark of Huang Ruixiang are common traditional Chinese medicines for treating rheumatism and pain relief, commonly known as Zushima, which have the functions of lowering blood fat, anti-hemolytic activity, anti-tumor activity and strong analgesia, and can also be used to treat arthritis and analgesia , anti-inflammatory, surgical anesthes...
