The planting prospect and resource yield of Bletilla striata, also known as Ganges Shabaigen, Baiwutou and Yangjiaoqi, etc. This is an orchid. Bletilla striata tuber is irregular, oblate, with 2~3 claw-like branches, and its surface is yellowish white or grayish white, which is a rare species. Mainly distributed in Guizhou, Sichuan, Yunnan, Guangxi, Zhejiang and other places in China, mainly produced in Sichuan, Yunnan and Guizhou. Detailed origin: Rumuli Tibetan Autonomous Prefecture in Xichang, Sichuan, with the main distribution center of Lotus Pond Medicinal Material Market in Chengdu, Sichuan; Wenshan, Simao, Lijiang and Chuxiong in Yunnan; Dushan, Zunyi, Anshun and other places in Guizhou; Huaihua in Hunan, Enshi in Hubei, Shangluo and Hanzhong in Shaanxi, and Funiu Mountain in Henan also provide commodities for the market, but the quantity is very small.

Bletilla striata grows in warm and humid valleys or shady places, with a long growth period. Once overexploited, it will take a long time to resume production. In recent years, with a large number of people's excavation, the distribution of Bletilla striata has dropped sharply, which makes the resources of Bletilla striata seriously insufficient and the output gradually decreases. At present, the supply of Bletilla striata in the market is in short supply, and the medicinal materials are much smaller and larger, with high moisture and poor quality. The farther away the place is, the more difficult it is to dig. The number of people digging is decreasing year by year, and the cost is getting higher and higher. Tracing back to the source, we know that the volume of goods this year is far less than last year, and the gradual increase in the price of Bletilla striata is also the general trend. Social investigation of bletilla striata.

Although cities are mainly concentrated in July ~ 10, in fact, Bletilla striata can be mined at other times except in winter, which makes many people unable to stock up. Even if the goods are stocked, the merchants will consider the cost, because once the goods are stocked, the storage cost will increase with the passage of time, and the cost will naturally rise. If the price increase is not large and there is no profit, no one will be willing to hoard. A few years ago, due to the shortage of funds in the pharmaceutical sector, the procurement of Bletilla striata was neglected, which led to the decline of Bletilla striata inventory. When manufacturers need a large number of goods, the market will often be out of stock, and sometimes the market will have an abnormal phenomenon of "no goods at a price". At present, the social stock of Bletilla striata is relatively weak.

Cold, bitter and dry, it has astringent, hemostatic, repercussive and granulation promoting effects. This is a good medicine for stomach trouble. Bletilla striata granules and oral liquid produced by single bletilla striata have remarkable curative effect, and sell well after listing, and the demand of manufacturers for Bletilla striata is correspondingly large every year. Bletilla striata is widely used as an adhesive in industrial production besides treating stomach diseases. For example, in cigarette production, Bletilla striata is used as an adhesive in cigarette holders, and the adhesive for mounting calligraphy and painting is also made of Bletilla striata. Bletilla polysaccharide gum can also be used to replace chemical thickener in daily chemical products, which has the functions of reducing irritation, protecting skin and delaying aging. With the deepening of research, development and utilization, the application scope of Bletilla striata is more and more extensive, resulting in an increasing demand for Bletilla striata.
