Embodiment 1

[0039] The black tiger seed seedling raising method that the embodiment of the present invention provides, comprises:

[0040] Seed selection: From the collected black tiger seeds, the seeds with plump seeds, brown seed coat and luster were screened out, and the thousand-grain weight of the seeds was 250g.

[0041] Wet sand storage: The screened seeds were stored in wet sand for 30 days, during which they were turned every 10 days, and the weight ratio of seeds to wet sand was 1:3.

[0042] Variable temperature treatment: the seeds stored in wet sand were treated at 5°C for 14hr and at 25°C for 10hr respectively, repeating twice.

[0043] Soaking treatment: Soak the seeds after the variable temperature treatment with the seed pretreatment solution for 20 hours, and then soak them in 0.1% potassium permanganate solution for 15 minutes. The weight ratio of gibberellin and naphthaleneacetic acid in the seed pretreatment solution is 4:1, and the The solute concentration is 50mg / L...

Embodiment 2

[0049] The black tiger seed seedling raising method that the embodiment of the present invention provides, comprises:

[0050] Seed selection: From the collected black tiger seeds, the seeds with plump seeds, brown seed coat and luster were screened out, and the thousand-grain weight of the seeds was 220g.

[0051] Wet sand storage: The screened seeds were stored in wet sand for 25 days, during which they were turned every 7 days, and the weight ratio of seeds to wet sand was 1:2.5.

[0052] Variable temperature treatment: the seeds stored in wet sand were treated at 1° C. for 13 hr and at 20° C. for 9 hr, respectively, and repeated twice.

[0053] Soaking treatment: Soak the seeds after the temperature-changing treatment with the seed pretreatment solution for 20 hours, and then soak them in 0.1% potassium permanganate solution for 15 minutes. The weight ratio of gibberellin and naphthaleneacetic acid in the seed pretreatment solution is 3:1. The solute concentration is 40mg...

Embodiment 3

[0059] The black tiger seed seedling raising method that the embodiment of the present invention provides, comprises:

[0060] Seed selection: From the collected black tiger seeds, the seeds with plump seeds, brown seed coat and luster were screened out, and the thousand-grain weight of the seeds was 245g.

[0061] Wet sand storage: The screened seeds were stored in wet sand for 26 days, during which they were turned every 8 days, and the weight ratio of seeds to wet sand was 1:2.6.

[0062] Variable temperature treatment: the seeds stored in wet sand were treated at 2°C for 14hr and at 21°C for 10hr, respectively, and repeated three times.

[0063] Soaking treatment: soak the seeds after the temperature-variable treatment with the seed pretreatment solution for 21 hours, and then soak them in 0.15% potassium permanganate solution for 16 minutes. The weight ratio of gibberellin and naphthaleneacetic acid in the seed pretreatment solution is 3.1:1, and The solute concentration...

Abstract

The invention provides a kadsura coccinea seed seeding growth method which comprises the following steps: pretreating kadsura coccinea seeds in a series of modes such as wet sand preservation, poikilothermic treatment and soaking with a plant hormone solution and a potassium permanganate solution, sowing the seeds into hone trays with sphagna as a medium in a culture chamber or a seedling growth greenhouse, controlling temperatures and humidity, shielding light, culturing till seedlings grow out, removing shade, carrying out normal temperature culture, and transplanting seedlings with 1-2 mainleaves into a field together with the medium. Compared with a conventional method, the method is capable of effectively breaking dormancy of kadsura coccinea seeds and promoting germination, the seedlings can grow out about 45 days ahead, the seeding growth time of the kadsura coccinea seeds can be shortened, the seedling rate is increased, the seedling rate is up to 90% or greater, and in addition, convenience in management is achieved. Improvement of the technique provided by the invention has great significances for improving the quality of kadsura coccinea forest nursery stock and promoting rapid development of the kadsura coccinea industry.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a seedling cultivation method of black tiger seeds. Background technique [0002] Black tiger is a plant of the genus Schisandra in the family Schisandraceae, also known as Lengfantuan, Guoshanlongteng, and Dazuan. It is an evergreen woody vine wild medicinal plant and wild fruit, mainly distributed in Guangxi, Yunnan, Hunan, Sichuan and other provinces (regions) In the miscellaneous forests of hillsides and valleys, it is often entangled with trees. The active ingredients that can be extracted from the roots and stems of black tiger are used in medicine to inhibit vasoconstriction, increase coronary blood flow, and have anti-hepatotoxic, tumor and peptic ulcer, anti-cancer, anti-AIDS and myocardial protection effects. The black tiger fruit is big and peculiar, smells fragrant, and the fruit is delicious and sweet. It is rich in vitamins and various trace elem...
