Is There a Subsidy for Bletilla striata Cultivation? A Full Analysis of Conditions and Risks

SummaryTemperature: It prefers a warm climate, but hot, stuffy conditions are not good for its growth, and it stops growing when the temperature is below 10°C. Light: It must not be grown in direct sunlight, otherwise the leaves are easily scorched, causing them to turn yellow and drop off. Soil: It is best grown in clay soil with a high content of organic matter and humus, with a pH preferably between 6.5-7.5. Fertilizer and water: Follow the principles of applying light fertilizer frequently, using small amounts more often, not watering when dry, and watering thoroughly when you do.

In the past, people were very unfamiliar with the Bletilla striata plant and had no idea what it was. But as its medicinal value has gradually been discovered, Bletilla striata has won people's hearts, and many people now want to grow this plant. However, people are still not very clear about the cultivation conditions for Bletilla striata and whether there are subsidies, so we will answer these questions for you.

Cultivation Conditions for Bletilla striata

1. Temperature: Bletilla striata likes a warm climate, but high temperatures and stuffy heat in summer (that is, above 35°C with relative air humidity above 80%) are not good for its growth. In winter it is very strict about temperature; when the growing environment is below 10°C, Bletilla striata stops growing, and during frost it may fail to survive the winter safely.

2. Light: Bletilla striata must not be grown in direct sunlight, otherwise it will grow very slowly or enter a semi-dormant state, and its leaves are easily scorched, beginning to turn yellow and drop off. Therefore, in the hot summer it is best to shade it from about 50% of the sunlight. In spring, autumn and winter, since the temperature is not very high, it should be placed where sunlight can reach it directly, to help it carry out photosynthesis and thus form flower buds, bloom and set seed normally. If Bletilla striata is grown indoors, place it as far as possible in a spot with bright light, such as a well-lit living room, bedroom or study. After being kept indoors for a period (about two months), it needs to be moved outdoors to a shaded spot (with insulation conditions if it is winter) for a period (generally about 30 days), and alternating this way is enough.

3. Soil: Bletilla striata is suitable for growing in clay soil (red or yellow soil) with a high content of organic matter and humus, with a pH preferably between 6.5-7.5, which is better for its growth, because Bletilla striata is a neutral-soil plant.

4. Fertilizer and water: Like other flowers and grasses, Bletilla striata has a relatively high demand for fertilizer and water, but fertilizer must not be applied carelessly; for example, applying concentrated fertilizer or applying only nitrogen, phosphorus or potassium fertilizer is not acceptable. Fertilization must be reasonable and scientific, following the two fertilization (and watering) principles of applying light fertilizer frequently, using small amounts more often, complete nutrition, and alternating dry and wet, drying thoroughly when dry, not watering when not dry, and watering thoroughly when watering. Also, after fertilizing, keep the leaves and flowers of Bletilla striata dry at night.

Is There a Subsidy for Bletilla striata Cultivation?

Whether there is a subsidy for Bletilla striata depends on local policies. Bletilla striata subsidies generally fall under medicinal herb cultivation subsidies. Many places provide certain subsidies and support for Chinese medicinal herb cultivation, but conditions differ from place to place, so you need to consult the relevant departments, and the reply from the local relevant department shall prevail. But if there is a subsidy, the following information is generally required:

1. Applicant: At present, subsidies are generally only given to Chinese medicinal herb cultivation of a certain scale, so applicants are generally agricultural entities such as cooperatives, large growers or family forest farms.

2. Application scale: Chinese medicinal herb cultivation subsidies generally have a scale requirement, commonly no less than 100 mu.

3. Subsidy standard: The subsidy standard differs in each region, but based on data from previous years, it is generally around 100-500 yuan/mu.

Cultivation Techniques for Bletilla striata

1. Soil selection: Sandy loam and humus loam with good drainage and much humus are suitable. Bletilla striata likes warm, slightly shady and damp environments, and it is not cold-tolerant. If planting on well-drained mountain land, choose a shady slope and virgin wasteland for planting.

2. Land preparation and bed making: Plow the soil more than 20 cm deep, apply about 1000 kg of farmyard manure per mu, then turn the soil again to mix the soil and fertilizer evenly. Before planting, break up the soil finely, rake it level, and make raised beds 130-150 cm wide.

3. Cultivation and weeding: After the Bletilla striata seedlings have emerged evenly, around May-June they grow very vigorously, but weeds also grow quickly, so weeding must be done in time. Weeding should be combined with loosening the bed surface, and when weeding be sure to hoe shallowly so as not to damage the roots of Bletilla striata.

4. Timely topdressing: Bletilla striata is a fertilizer-loving plant. It is best to spray potassium dihydrogen phosphate or diluted human and livestock manure once a month until July-August, when Bletilla striata stops growing and enters dormancy. Throughout the process, take care to prevent weeds from overgrowing.

5. Irrigation and drainage: Bletilla striata likes shade and needs to be kept moist often. Water it promptly in dry periods. In July-September it is best to water once in the morning and once in the evening, but Bletilla striata also fears waterlogging, so drain promptly in heavy rain and other weather to avoid root damage.

Propagation Methods for Bletilla striata

Sowing Bletilla striata from seed is generally quite difficult, so artificial propagation basically uses tuber division. From September to early November each year, dig up the Bletilla striata and select medium-sized, disease-free tubers with many buds; those with 1-2 buds per piece are better. Dip them in plant ash and then plant them.

The suitable spacing between furrows is 20-25 cm, with a depth of 5-6 cm. Place one tuber every 10-12 cm along the row, with the buds facing upward. After filling with soil, press it firm, then water and cover with grass, keeping the environment moist often. Seedlings generally emerge in March-April.

What Risks Are There in Growing Bletilla striata?

1. Market risk: Bletilla striata was previously mainly grown in Yunnan, Sichuan, Guizhou and other places in China, while in recent years Shaanxi, Henan, Zhejiang, Guangxi, Jiangsu, Fujian, Gansu and other places have also seen large areas of artificial cultivation. Therefore, overheated cultivation and production may pose a certain risk to the market price of Bletilla striata.

2. Investment risk: Compared with other Chinese medicinal herb cultivation projects, Bletilla striata cultivation requires a larger investment cost, and its growth period is generally about 2-3 years. The large investment cost and long production cycle put considerable economic pressure on ordinary growers, greatly increasing the risk in terms of capital input.

3. Seed source risk: There are many varieties of Bletilla striata, and variety selection in Chinese medicinal herb cultivation is rather chaotic. What circulates in the chemical industry is mainly purple-flowered large three-fork Bletilla striata, while what circulates for medicinal use in Chinese medicine is mainly purple-flowered small three-fork Bletilla striata. Others such as yellow-flowered and white-flowered Bletilla striata are customary products or counterfeit products, so variety selection also carries a certain risk.

4. Technical risk: Bletilla striata seedlings generally have to go through introducing seed sources, then tissue culture and hardening, and only after the roots and fibrous roots are well developed are they transplanted. In this process, because the growth of the rhizome requires an environment with symbiotic bacteria, and the transplanting and management requirements for Bletilla striata are very fine, the seedling death rate can sometimes reach 50% or even higher, so the technical requirements are very high, and the technical risk is not small either.

What is clear is that Bletilla striata is currently in great demand on the market, so successful cultivation will certainly bring good economic returns. But we all know that planting and breeding carry risks, so everyone should still consider carefully.
