Seedling growing method of bletilla striata

Abstract

The invention provides a seedling growing method of bletilla striata. The method comprises the following steps: the whole seedling growing process is divided into two stages, wherein in the first stage, seeds are uniformly scattered on the surface layer of a culture medium and germination cultivation is conducted in a tissue culture chamber; and after the seeds are germinated to form protocorms, second-stage cultivation is conducted, the protocorms are stripped from the culture medium and are put into water, the protocorms are scattered on a seedling bed after being dispersed, the protocorms are exposed on the substrate, nutritional liquid is sprayed on the seedling bed at fixed period, moisture preservation, temperature control and shading of the seedling bed are considered, direct sunlight is prevented, and water and fertilizer management as well as disease prevent and control management are conducted. The seedling growing method of the bletilla striata is high in germination efficiency, short in germination time, simple and convenient in management and low in seedling growing cost. Germination can be completed after 10 to 15 days and tissue culture chamber cultivation can be completely after 30 to 35 days. Inoculation on the culture medium is needed only for one time, the protocorms are scattered on the seedling growth substrate after being formed and seedling growing is conducted.

Description

[0001] basic field [0002] The invention belongs to the technical field of seedling cultivation, and in particular relates to a method for cultivating bletilla striata seedlings. Background technique [0003] Bletilla striata is a traditional Chinese medicinal material in my country, but its seeds have a low germination rate in nature due to the lack of endosperm, and now wild resources are decreasing. In order to meet people's demand for this medicinal material, people began to try artificial breeding and cultivation. Now the common Bletilla striata seedling methods are mainly divided into two categories: plant tissue culture rapid propagation and live seedling cultivation. [0004] In the existing technology, seedlings raised by traditional tissue culture technology need to go through one sowing and two medium transfers, and the labor cost is very high; while the germination rate of direct seeding seedlings is too low, less than 5%, so the demand for seeds is particularly l...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, seedlings raised by traditional tissue culture technology need to go through one sowing and two medium transfers, and the labor cost is very high; while the germination rate of direct seeding seedlings is too low, less than 5%, so the demand for seeds is particularly large, and the germination rate is very high. The protocorm grows very slowly, resulting in a very long seedling cycle, more than one year, and the risk of raising seedlings increases

However, the cost of raising seedlings in these studies is too high, which is not conducive to the cultivation of Bletilla striata
