Embodiment 1

[0030] (1) Seed collection. In September 2015, the white and mature fruit pods were collected from the Baihe planting base in Gejiu City, Yunnan Province, and brought back to Kunming, dried indoors, stored at room temperature, and carried out direct seedling cultivation in March of the following year.

[0031] (2) Germination of seeds. Shake off the powdered seeds of Baijishuguo in a 50ml centrifuge tube, and pour into the 0.1-1.0 mg / L naphthalene acetic acid (NAA) or 0.1-0.5 mg / L indole acetic acid (IAA) solution In the centrifuge tube, cover the centrifuge tube lid, centrifuge or shake vigorously to make the seeds fully contact the solution. Place the centrifuge tube in a water bath with a water temperature of 40-45°C for 3 minutes, then take it out immediately, and place it indoors for 1 hour to incubate the germination. During the period, be careful to shake the centrifuge tube. After the time is over, centrifuge, discard the upper layer of solution, and set aside.

Embodiment 2

[0040] Except for the step (3) to prepare the seed germination support and finally pour the mixture into a plastic pot with a thickness of between 2-3 cm, the other steps are the same as in Example 1.

Embodiment 3

[0042] Except for step (4) after sowing, sprinkle a layer of powdered fresh red clay and water with a watering can to make the seedbed fully moist, the other steps are the same as in Example 1.

Abstract

The invention relates to a Bletilla striata greenhouse direct seeding and seedling method using seeds as material. The Bletilla striata greenhouse direct seeding and seedling method comprises the following steps of seed collecting, seed germinating, preparation of seed germinating support matter, culture of original bulb seeds, seeding into a seedling bed in an arch greenhouse, managing, transplanting and the like. The Bletilla striata greenhouse direct seeding and seedling method has the advantages that the problems of no endosperm due to fine and small seeds, and difficulty in germinating under the natural condition are solved; the operation is simple, and the implementing is easy; the germinating rate is 84.90+ / -0.72 to 90.26+ / -0.85, and the rate of finished seedling is high; after seeding for 180d, the plant height reaches 5cm, and the height of highest plant is 10cm or above; the diameter of pseudobulb is 0.8 to 1.6cm, and the seedling cost of the Bletilla striata is greatly reduced.

Description

Technical field [0001] The present invention belongs to a method for the sexual reproduction of plants, and also relates to a method for the reproduction of seeds of orchidaceous plant A. Background technique [0002] White and ( Bletilla striata ) Belongs to the genus Orchidaceae (Orchidaceae) Bletilla ) Perennials, "and" and "Ji" are common, and are distributed in Yunnan, Guizhou, Sichuan, Guangxi, Shaanxi, Anhui and other places in China. White and dried fake bulbs are traditional precious medicinal materials in my country, and the market demand is large. There are thousands of seeds in a single pod of Baiji, but its seed characteristics are extremely special. The seeds are powdery, very small and have no endosperm to provide nutrition, and the seeds are difficult to raise seedlings by direct seeding and are sensitive to the environment. White and seedling propagation methods mainly adopt tuber asexual propagation and tissue culture. The former uses a large amount of seed a...
