Method for raising seedlings of rhizoma bletillae seeds in cold highland area

Abstract

The invention discloses a method for raising seedlings of rhizoma bletillae seeds in a cold highland area. The method specifically comprises the following steps of S1, harvesting and storing capsules; S2, preparing a seedling raising substrate, wherein the seedling raising substrate is composed of turf, wood chips and raw red soil, the raw red soil is laid on the bottom layer, and the turf and the wood chips are mixed and then laid on the raw red soil; S3, pretreating the seeds, namely mixing fine sand with the seeds in advance; S4, directly sowing the seeds, namely putting the pretreated seeds into a sowing bottle, and sowing the seeds on the seedling raising substrate by using the sowing bottle so as to ensure that the seeds are uniformly sown, wherein the direct sowing time is from February to May every year, and the direct sowing of the seeds needs to be performed in a shed; S5, spraying a seed germination agent, namely after direct sowing of the seeds, spraying the seed germination agent on the surface of the seedling raising substrate; and S6, managing water, namely using a cross-shaped atomization sprinkler for sprinkling irrigation. The method can solve the problems that the rhizoma bletillae seeds are small, free of embryos and incomplete in development and can germinate only after mycosymbiosis under natural conditions, and rhizoma bletillae seed seedling raising in the cold highland area is achieved.

Description

technical field [0001] The invention relates to the technical field of bletilla planting, in particular to a method for raising seedlings of bletilla in alpine mountainous areas. Background technique [0002] Baiji Bletilla striata is a variety recorded in the "Chinese Pharmacopoeia" in previous editions, and has the effects of astringent and hemostasis, detumescence and muscle growth. At present, in addition to being directly used in prescriptions as decoction pieces, Baiji is also widely used in compound Chinese patent medicines and industrial production. The developed Baiji Chinese patent medicine products include: Baiji Capsules, Compound Burn Spray, Vascular Embolism, Appetizer Tablets and Baiji Plasma Substitute made of Baiji Glue; industrial products include emulsifiers and suspensions. Whitening also has the effect of whitening and removing freckles. It has also been widely used in the fields of health care products and cosmetics in recent years, and the demand is i...
