Problems solved by technology

The plant Huang Ruixiang is currently a wild resource. It is the base 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 the origin of the Zushima base plant. Extremely in short supply; and because Daphne rhizome seeds have hardness, germination rate is very low, is difficult to meet production demand; This will certainly affect the reproduction of Daphne rhizome plant and the full utilization of medicinal value of Daphne rhizome plant; There is no relevant promotion in the prior art The report on the method of breaking the hard seed for the germination of Rhizoma chrysogenum seed, it is urgent to provide a method for breaking the hard seed to promote the germination of the seed

Embodiment 1

[0029] The method for breaking hard solids that promotes the germination of Daphne chrysantha seeds comprises the following steps:

[0030] a) acid etching step: use 98% concentrated sulfuric acid to acid etch Daphne radix seeds for 60 minutes;

[0031] b) Hormone treatment step: soak the seeds after the acid etching treatment with 0.2 mg / L gibberellin;

[0032] c) Determination of germination rate: sowing the hormone-treated seeds in plug trays, adding appropriate amount of water every day, and regularly observing the germination of the seeds, and calculating the germination rate of the seeds.

[0033] Measurement results: the germination rate of Daphne chrysanthemum seeds was 24.22%, and the germination potential was 16.29%.

Embodiment 2

[0035] The method for breaking hard solids that promotes the germination of Daphne chrysantha seeds comprises the following steps:

[0036] a) acid etching step: use 98% concentrated sulfuric acid to acid etch Daphne radix seeds for 40 minutes;

[0037] b) Hormone treatment step: soak the seeds after the acid etching treatment with 0.5 mg / L gibberellin;

[0038] c) Determination of germination rate: sowing the hormone-treated seeds in plug trays, adding appropriate amount of water every day, and regularly observing the germination of the seeds, and calculating the germination rate of the seeds.

[0039] Measurement results: the germination rate of Daphne japonica seeds was 6.38%, and the germination potential was 6.38%.

Embodiment 3

[0041] The method for breaking hard solids that promotes the germination of Daphne chrysantha seeds comprises the following steps:

[0042] a) acid etching step: use 98% concentrated sulfuric acid to acid etch the Daphne radix seeds for 20 minutes;

[0043] b) Hormone treatment step: soak the seeds after the acid etching treatment with 0.1 mg / L gibberellin;

[0044] c) Determination of germination rate: sowing the hormone-treated seeds in plug trays, adding appropriate amount of water every day, and regularly observing the germination of the seeds, and calculating the germination rate of the seeds.

[0045] Measurement results: the germination rate of Daphne japonica seeds was 6.38%, and the germination potential was 2.18%.

Abstract

The invention discloses a hard seed breaking device for promoting daphne giraldii seeds to germinate, belonging to the field of quality identification and cultivation of traditional Chinese medicine seeds. The method comprises the following steps: seed pre-treatment and hormone treatment. The hard seed breaking device disclosed by the invention is simple, convenient and feasible and has a reliable principle, good repeatability and good hard seed breaking effect; the hard seeds 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 24.22% and the germination potential is up to 16.29%.

Description

technical field [0001] The invention belongs to the field of quality identification and cultivation of Chinese medicinal material seeds, and particularly relates to a method for breaking hard seeds for promoting the germination 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 2000-3000m. 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-infl...
