Description
Technical field
The invention belongs to bletilla artificial cultivation technique field, be specifically related to a kind of Fast-propagation and sunlight method in strong sprout of bletilla.
Background technology
Bletilla (Bletilla striata (Thunb) Reichb.f) belongs to herbaceos perennial for the orchid family bletilla, widely distributed.The stem tuber of bletilla is China's traditional Chinese medicine, and just on the books in Shennong's Herbal, bletilla pattern is gorgeous in addition, also be a kind of ornamental plants, the demand of market to bletilla expands year by year, and bletilla suffers excessive excavation, cause its wild natural resources sharply to reduce, frequently face extinction.By one of country's Wild Medicinal being classified as focused protection, the wild natural resources of protection bletilla, artificial propagation is imperative with plantation bletilla.The traditional cultivation of bletilla is mainly by division propagation; the division propagation cycle is long, reproductive efficiency is low, consumption kind of amount is large; be difficult to satisfied a large amount of plantation demand; the seed of bletilla is tiny, hypoplasia, without endosperm; be difficult under natural conditions sprout, but bletilla seed is sprouted and is grown comparatively fast on synthetic medium, therefore utilizes plant tissue culture technique can fast breeding bletilla seedling in a large number; to the utilization of bletilla resource, protection and artificial scale, intensive cropping are significant.
Summary of the invention
The object of this invention is to provide a kind of Fast-propagation and sunlight method in strong sprout of bletilla, the method can reduce the cycle of breeding, and pseudobulb is large, and plantation survival rate is high.
The technical solution used in the present invention is a kind of Fast-propagation and sunlight method in strong sprout of bletilla, and the method comprises the following steps:
