Embodiment Construction

[0015] Examples are given below to describe the present invention in detail.

[0016] In this embodiment, the site is selected to be carried out in a certain area of ​​Hunan Province in the area of ​​28-30 degrees north latitude, which is 30 degrees north latitude, low mountainous area, and about 500 meters above sea level. Seedbed area of ​​200 square meters.

[0017] In the bletilla striata seed collection nursery built in 2008, artificial assisted pollination was carried out during the flowering period of bletilla striata in May-June 2011: use a toothpick to pick the pollen block above the columella, and then stuff the pollen block into the pollen block of another flower Below the insertion, below the septum, on the stigma with obvious staining. After pollination of 3-5 flowers per inflorescence is completed, the redundant opened or unopened flowers at the front of the inflorescence are cut off.

[0018] When the fruit is ripe, that is, the seeds in the fruit are no longe...

Abstract

The invention discloses a method for realizing sexual reproduction and seedling culture of bletilla under an imitated ecological condition, wherein the large-scale production of bletilla seedlings is realized by using bletilla seeds in a near natural environment, namely under the imitated ecological condition. The method comprises the following steps of artificial supplementary pollinating bletilla, collecting and storing bletilla seeds, building a sowing condition, sowing and early managing after the sowing, and nurturing bletilla seedlings. By the method disclosed by the invention, the problem that the setting percentage of wild bletilla is low is solved, the sexual reproduction of the bletilla is performed under the imitated ecological condition which is built through imitating the nature; the survival rate and the growth density of the reproduced seedlings are high; the scale operation can be realized; the method is easily popularized and applied.

Description

technical field [0001] The invention relates to a method for sexual reproduction of plants, that is, a complete method for cultivating a large number of bletilla striata seedlings by means of sexual reproduction. More specifically, on the basis of solving the problem of low natural seed setting rate of wild bletilla striata, under the simulated ecological conditions established by nature, sow bletilla striata seeds, and through a specific maintenance process, a large number of endangered wild medicinal plant bletilla striata seedlings are bred. suite of methods. Background technique [0002] Bletilla striata is an endangered wild medicinal plant. Its rhizome is used as medicine, which has outstanding pharmacological effects such as internal and surgical hemostasis, and is a traditional Chinese medicinal material. In addition, the rhizome of Bletilla striata also contains up to 50% of Bletilla striata gum, which has similar physical and chemical properties to imported gum ...
