Breeding method of rhizoma bletillae seedlings

Abstract

The invention discloses a breeding method of rhizoma bletillae seedlings, and belongs to the technical field of traditional Chinese medicinal material plantation. According to the breeding method, tissue culture propagation is adopted. The breeding method comprises following steps: 1, seedling collecting; 2, culture medium selecting; 3, seedling breeding, wherein seed germination induction, induced bud differentiation, rooting induction, and greenhouse seedling hardening are adopted; 4, bottle seedling emergence; 5, removing of bottle seedlings out from bottles and processing; 6, domesticated plant cultivation management; and 7, domesticated plat emergence. Compared with the prior art, the breeding method possesses following advantages: a defect of propagation by tuber that seed consumption amount is large is avoided; rhizoma bletillae tissue culture plant survival rate is increased; rhizoma bletillae seedling domestication cultivation measures are provided, and domesticated plant survival rate is increased; rhizoma bletillae culture medium formula ratio, bottle seedling, and domesticated plant seedling emergence standards are standardized, and lack of technology and standards in large-scale production is avoided effectively.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and in particular relates to a method for propagating baiji seedlings. Background technique [0002] White and [ Bletilla striata (Thunb. ex A. Murray) Rchb. f.] is a perennial herbaceous plant belonging to the family Orchidaceae, with a plant height of 18-60cm; the pseudobulb is oblate and spherical, with a water chestnut-like ring on the top, which is sticky; the stem is thick and straight; 4-6 leaves, narrowly oblong or lanceolate, 8-29cm long, 1.5-4cm wide, apex acuminate, base narrowed into sheaths and clasping stems; inflorescences with 3-10 flowers, often unbranched or Very rarely branched; inflorescence rachis more or less zigzagged; bracts oblong-lanceolate, 2-2.5cm long, often withered when blooming; large, purple or pink flowers; sepals and petals close Equal length, narrowly oblong, 25-30mm long, 6-8mm wide, apex acute; petals slightly wider than sepals...

AI Technical Summary

Problems solved by technology

In recent years, due to the needs of the development of the white and the industry, the tissue culture technology of the white and the seedlings has begun to rise and gradually become an important source of the supply of the white and the seedlings, but the mortality of the white and the tissue culture seedlings is high, the phenomenon of invalid seedlings exists, and the production cycle Longer et al. have imposed certain restrictions on the use of tissue cultured seedlings to relieve blight and large-scale industrial planting. Optimizing blight and tissue culture technology and promoting the supply of high-quality seedlings will be very important for the healthy development of blight and the industry.
