How much does a Bletilla striata (purple-flowered) seedling cost per plant, and what are its cultivation prospects?

Purple-flowered Bletilla striata is also called three-fork purple-flowered Bletilla striata. It is currently grown quite widely in Yunnan and other regions, and it is a variety of Bletilla striata that bears purple flowers, so it has a certain ornamental value. Of course, purple-flowered Bletilla striata is also a medicinal herb and has a certain economic value on the market, which has driven the living income of many local farmers. So how much does a Bletilla striata seedling cost per plant? What are its cultivation prospects?

1. How much does a Bletilla striata seedling cost per plant?

The price of Bletilla striata seedlings is roughly 0.8-4 yuan per plant. The price is affected by many factors, and there are certain differences from place to place. For example, if the purchase quantity is different, the plant size is different, or the purchase channel is different, the price will also be cheaper or more expensive.

2. Cultivation prospects of purple-flowered Bletilla striata

1. Growing demand for Bletilla striata: Bletilla striata originally belonged to a minor variety among traditional Chinese medicine commodities. In the 1950s-1980s, the national demand for medicinal use did not exceed 200 tons. In the 1986 national survey of traditional Chinese medicine, the resource status of Bletilla striata and its commodity production, supply, sales, and inventory were not included in the statistical scope, because at that time it was a minor variety that could be ignored. However, times have changed. China's current demand for Bletilla striata has increased by 5-10 times compared with 20 years ago, reaching several thousand tons.

2. Wide range of uses: Bletilla striata can be used as an adhesive when dyeing cloth, as an adhesive for high-grade cigarettes, as an adhesive for mounting Chinese calligraphy and paintings, and as a repair agent for broken roots of wild mountain ginseng. For thousands of years, Bletilla striata has been used as a traditional Chinese medicine. Its main functions are astringing sores and stopping bleeding, tonifying the lungs, reducing swelling, and promoting tissue regeneration. Modern scientific research has proved that the tubers of Bletilla striata are rich in a large amount of water-soluble polysaccharides, whose chemical component is glucomannan, which is the main functional component of Bletilla striata gum. Bletilla striata polysaccharide gum is an excellent natural food thickener, and it is also a relatively safe pharmaceutical raw material, a pharmaceutical excipient with outstanding performance, and a biomedical material with considerable development prospects. In addition, Bletilla striata polysaccharide gum can also be used in daily chemical products to replace chemical thickeners, and it has functions such as reducing irritation, protecting the skin, and delaying aging. With the continuous deepening of research, the scope of application of Bletilla striata is becoming wider and wider, which has led to an increasing demand for Bletilla striata.

3. Extinction-style harvesting: Stimulated by prices, when wild Bletilla striata is harvested, no plant is left behind regardless of size. The higher the price, the more cleanly it is dug up. Because Bletilla striata reproduces by pseudobulbs, this harvesting method is an important reason why, whenever a wild population of Bletilla striata is found, it is dug up, and then goes extinct. Bletilla striata should originally be harvested from October to December, when its pseudobulbs are large and plump, with high gum content and good quality, and the fresh-to-dry ratio is high. However, because the market price is high and germplasm resources are scarce, in recent years it has always been harvested early during the flowering period in April. As a result, the immature pseudobulbs are shrunken, the fresh-to-dry ratio is extremely low, and the medicinal quality standard cannot be met at all. In this way, the reduced yield and income caused by premature harvesting year after year have also artificially caused a large amount of resource waste.

4. The growing environment of Bletilla striata is becoming increasingly worse: The scope of human activity is becoming wider and wider, and wasteland and grassy areas are becoming fewer and fewer. The ecological conditions of Bletilla striata have suffered great damage. In particular, in recent years, mountainous areas such as Yunnan, Guizhou, and Sichuan have developed forestry and fruit economies, extensively reclaimed barren slopes, and planted fruit, tea, and medicinal herbs in diversified operations, destroying the natural conditions on which Bletilla striata depends for survival. Bletilla striata has lost the spatial conditions for survival and reproduction, the remaining soil resources are becoming fewer and fewer, and Bletilla striata commodities are also becoming increasingly scarce.

5. Irreplaceable miraculous efficacy and wide range of uses: The most fundamental reason for the scarcity of Bletilla striata is still its miraculous efficacy. It is slightly cold in nature and bitter, sweet, and astringent in taste, and has the functions of astringing to stop bleeding and reducing swelling to promote tissue regeneration. It is used for tuberculosis with blood vomiting, hemoptysis due to bronchiectasis, hematemesis due to gastric ulcer, hematuria, bloody stool, and other symptoms, and can also be used for symptoms such as bleeding from trauma. The miraculous efficacy and wide range of uses of Bletilla striata have also accelerated the extinction of its resources.
