Problems solved by technology
[0003] During the hardening process of tissue culture seedlings, the conventional seedling beds are mainly groove-shaped flat beds, which have poor air permeability and drainage, and difficult control of substrate moisture, which affects the seedling growth rate of Bletilla striata; it is urgent to design a kind of drainage, air permeability, and low cost. The Bletilla striata tissue culture seedling bed can not only increase the seedling rate, reduce management costs, but also facilitate manual operation and improve production efficiency

Embodiment
[0030] Use the rooting bottled seedlings cultured by the stem tip tissue of Bletilla striata, wash off the medium of the roots, then plant them in the seedling tray, and then plant them in the perlite matrix, with a plant and row spacing of 2cm×3cm, and carry out conventional fertilizer and water management in the greenhouse; 30 ~40 days, when the seedlings grow to 5cm~10cm high, they are transplanted to the cultivation substrate of the corrugated seedbed for cultivation; after one year of cultivation, the seedling height reaches 20~25cm, the tuber diameter reaches 1cm~2cm, and the number of hair roots reaches 5 to 10 plants, with a root length of more than 10cm, can be transplanted or sold as seedlings for field production;

The invention discloses a waveform-seedling-culturing-bed seedling exercising method of bletilla-striata tissue culture seedlings. The method includes the following specific steps of selecting and conserving of the tissue culture seedlings and transplanting and cultivating of the conserved seedlings, and the method also includes the steps of building and using of a waveform seedling culturing bed.According to the method, the waveform seedling culturing bed is adopted in the seedling exercising process, draining and ventilating can be conducted on media, the foot rot condition is relieved, thevolume of the media can also be increased through waveforms, growth of roots of the tissue culture seedlings is promoted, the seedling rate and the quality of the bletilla-striata tissue culture seedlings during seedling exercising are improved, and market requirements are met.
Description
technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, in particular to a method for cultivating bletilla striata tissue cultured seedlings in a corrugated seedling bed. Background technique [0002] The medicinal plant Bletilla striata (scientific name: Bletilla striata), is a perennial herb of the genus Bletilla striata in the family Orchidaceae. It has the effects of hemostasis, tonifying the lungs, promoting muscle and relieving pain; with the increase of market demand, the over-harvesting of wild bletilla striata has led to the depletion of wild resources. At present, the research on artificial cultivation of bletilla striata has gradually matured. Gradually increase the amount, use artificial tissue culture seedlings to expand the seedling supply market, improve the production and quality of bletilla striata, to meet market demand. [0003] During the hardening process of tissue culture seedlings, the conventional see...
