Embodiment 1

[0032] (1) Seed collection. In September 2015, the mature pods of Baiji were collected from the Baiji planting base in Gejiu City, Yunnan Province, and brought back to Kunming, where they were dried in the shade and stored at room temperature, and seedlings were raised by direct seeding in March of the following year.

[0033] (2) Seed germination. Shake off the powdered seeds of Baijisuo fruit into a 50ml centrifuge tube, then pour 0.1-1.0 mg / L naphthalene acetic acid (NAA) or 0.1-0.5 mg / L indole acetic acid (IAA) solution into it In a centrifuge tube, cover the centrifuge tube cap, centrifuge or shake vigorously to make the seeds fully contact with 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 to keep germination for 1 hour, and shake the centrifuge tube carefully during this period. After the time is over, perform centrifugation, pour off the upper layer solutio...

Embodiment 2

[0042] Other steps are the same as in Example 1, except that step (3) prepares a seed germination support and finally pours the mixture into a plastic pot with a thickness of 2-3 cm.

Embodiment 3

[0044] Except that step (4) sprinkles a layer of powdered fresh red soil after sowing, and waters with a watering can to make the seedbed fully moist, 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 invention belongs to a method for sexual reproduction of plants, and also relates to a method for the reproduction of orchid plants and their seeds. Background technique [0002] White and ( Bletilla striata ) for Orchidaceae (Orchidaceae) white and genus ( Bletilla ) Perennial plants, "ji" and "ji" are commonly used, and are distributed in Yunnan, Guizhou, Sichuan, Guangxi, Shaanxi, Anhui and other places in China. White and dry pseudobulb is a traditional precious medicinal material in my country, and the market demand is relatively large. There are tens of thousands of seeds in a single pod, but its seed characteristics are very special. The seeds are powdery, very small and have no endosperm to provide nutrition. It is difficult to grow seedlings by direct seeding and is sensitive to the environment. The propagation methods of Baiji seedlings mainly adopt tuber vegetative propagation and tissue culture. The former uses a large amount of se...
