Planting prospect of Bletilla striata

From 4.8 yuan per kilogram in 1992 to about 600 yuan per kilogram in 2015, it has risen all the way, especially in recent years, traditional Chinese medicine has been recognized by the international market, and the price has soared all the way. At present, the supply of Bletilla striata basically depends on wild resources. Since 2014, the supply of goods from the market and origin has been seriously insufficient, and it is not suitable to organize supply.

2. Bletilla striata can also be propagated by sowing, but the seeds of Bletilla striata are very small and have no endosperm, so it is difficult to germinate and grow in nature, and it is difficult to cultivate seedlings.

3. Tissue culture technology can rapidly propagate a large number of seedlings, sow aseptic seeds on different media, and propagate clones by tissue culture after seed germination, so as to realize the large-scale production of Bletilla striata seedlings and explore effective rapid propagation techniques.
