Embodiment Construction

[0015] The present invention is described in detail with examples below.

[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 longer ag...

Abstract

Provided is a method for realizing bletilla striata sexual propagation seedling growing in an imitative ecological condition. In the method, bletilla striata seeds are used to realize large-scale production of bletilla striata seedlings in environment close to natural environment, that is, under an imitative ecological condition. The method comprises steps: bletilla striata artificial supplementary pollination, bletilla striata seed harvesting and storage, construction of sowing conditions, sowing and after-planting early-stage management, bletilla striata seedling tending. The method solves aproblem of low natural seed set rate of wild bletilla striata, and simulates nature and establishes an imitative ecological condition to perform bletilla striata sexual propagation, seedling breedingsurvival rate is high, growth density is high, and the method can realize large-scale operation, and is easy for popularization and application.

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 a...
