Is there a subsidy for Bletilla striata cultivation? what are the risks of planting Bletilla striata?

Temperature: like a warm climate, but it is not conducive to growth in a hot and muggy environment, and it will stop growing when the temperature is below 10 ℃. Lighting: can not be cultured in direct sunlight, otherwise the leaves are prone to burns, resulting in yellowing and shedding. Soil: it is suitable to grow in clayey soil with high content of organic matter and humus, and the ph value is preferably between 6.5 and 7.5. Fertilizer and water: follow the principle of frequent application of light fertilizer, less and more times, no dry, no watering, watering thoroughly.

In the past, people were so strange to Bletilla striata that they had no idea what it was. However, with the medicinal value of Bletilla striata gradually being excavated by people, Bletilla striata began to gain popularity. At present, many people want to plant this plant. However, the planting conditions of Bletilla striata and whether there will be subsidies and other things are not very clear, the editor will answer for you.

Planting conditions of Bletilla striata

1. Temperature: Bletilla striata likes a warm climate, but it is not conducive to its growth in summer when it is hot and muggy (that is, more than 35 ℃ and the air relative humidity is more than 80%). The temperature is very strict in winter. When the temperature of the growing environment is below 10 ℃, Bletilla striata will stop growing, and it may not be safe to survive the winter in frost season.

2. Illumination: Bletilla striata can not be cultured in direct sunlight, otherwise it will grow very slowly or enter a semi-dormant state, and its leaves will be easily burned and will begin to turn yellow and fall off. Therefore, it is best to shield it from about 50% of the sun on a hot summer day. Bletilla striata in spring, autumn and winter, because the temperature is not very high, it should be placed in a place where the sun can shine directly, in order to facilitate its photosynthesis, thus normal flower bud, flowering and fruiting. If you put Bletilla striata in indoor breeding, you should try to put it in a place with bright light, such as a well-lit living room, bedroom or study. After indoor maintenance for a period of time (about two months), it needs to be moved to an outdoor place with shade (if it is winter, there should be heat preservation) for a period of time (usually about 30 days), so that it can be exchanged alternately.

3. Soil: Bletilla striata is suitable to grow in clayey soil (red or yellow soil) with high content of organic matter and humus, and the best PH value is between 6.5 and 7.5, which is more conducive to the growth of Bletilla striata, because Bletilla striata is a neutral native plant.

4. Fertilizer and water: like other flowers and plants, Bletilla striata requires more fertilizer and water, but it is not feasible to apply fertilizer indiscriminately, such as concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer. Fertilization should be reasonable and scientific. Follow the two principles of fertilization (water) that light fertilizer is applied frequently, less and more times, complete nutrition and wet, dry and thoroughly, not dry and watered, and after fertilizer application. Leaves and flowers of Bletilla striata need to be kept dry at night.

Is there a subsidy for planting Bletilla striata?

Whether Bletilla striata has subsidies depends on the relevant local policies. Bletilla striata subsidies generally belong to the subsidies for the cultivation of Chinese medicinal materials. Many places will provide certain subsidies and support for the cultivation of Chinese herbal medicines, but the situation is different in different places. Therefore, you need to consult the relevant departments, subject to the reply of the relevant local departments, but if there is a subsidy, you generally need to provide the following information:

1. Application object: at present, it only subsidizes the cultivation of traditional Chinese medicine on a certain scale, so the application objects are generally agricultural subjects such as cooperatives, large growers or family forest farms.

2. Application scale: general subsidies for the cultivation of traditional Chinese medicine all have a scale requirement, and the common one is not less than 100 mu.

3, subsidy standard: the subsidy standard of each region is different, but according to the data of previous years, it is generally about 100-500 yuan / mu.

Planting technique of Bletilla striata

1. Soil selection: it is appropriate to drain well the sandy loam and humus loam with high humus content. Bletilla striata prefers warm and slightly humid environment, and it is not cold-resistant. Shady slope wasteland should be selected for planting in mountainous areas with good drainage.

2. land preparation: ploughing the soil for more than 20 centimeters, applying about 1000 kilograms of farm manure per mu, and then turning the land to mix the soil and fertilizer evenly. Before planting, the soil needs to be fine, raked flat and make a high border with a width of 130-150cm.

3. Ploughing and weeding: after the seedlings of Bletilla splendens come out, they grow very vigorously around May-June, but weeds also grow very fast, so weeding should be carried out in time. Weeding should be combined with cuddling the border surface, and pay attention to shallow hoeing when weeding, so as not to hurt the roots of Bletilla striata.

4, timely topdressing: Bletilla striata is a fertilizer-loving plant, it is best to spray potassium dihydrogen phosphate or thin human and animal feces once a month, until July-August Bletilla splendens will stop growing into dormancy, the whole process should pay attention to prevent weeds.

5, irrigation and drainage: Bletilla striata likes yin and needs to be kept moist frequently, and it is necessary to water it in time when it is dry. It is best to water it in the morning and evening from July to September, but Bletilla striata is also afraid of waterlogging, so it is timely to drain water in case of heavy rain and other weather to avoid root damage.

Propagation methods of Bletilla striata

It is generally difficult for Bletilla striata to sow seeds, so artificial propagation is basically based on tubers. Every year from September to early November, Bletilla striata is dug out, selecting medium-sized tubers with many bud eyes and disease-free tubers, each with 1-2 buds is better, dipped in plant ash before planting.

The suitable distance of ditching is 20-25cm, 5-6cm deep, one tuber per 10-12cm, the buds should be upward, compacted after filling the soil, and then watered to cover the grass, often keep the moist environment, generally will emerge in March-April.

What are the risks of planting Bletilla striata

1. Market risk: in the past, the main planting areas of Bletilla striata in China were Yunnan, Sichuan, Guizhou and other places, but in recent years, Shaanxi, Henan, Zhejiang, Guangxi, Jiangsu, Fujian, Gansu and other places also have a large area of artificial planting, so overheated planting production may form a certain risk to the market price of Bletilla striata.

2. Investment risk: the investment cost of Bletilla striata planting is higher than that of other traditional Chinese medicine planting projects, and its growth life is generally about 2-3 years. The large investment cost and long production cycle have greater economic pressure on the general growers, which greatly increases the risk of capital investment.

3. Provenance risk: there are many varieties of Bletilla striata, and the selection of products in the cultivation of traditional Chinese medicine is more confused. the circulation in the chemical field is mainly purple Trigeminal Bletilla striata, while the medicinal circulation of traditional Chinese medicinal materials is mainly purple Trigeminal Bletilla striata. Others, such as yellow flower, Bletilla striata and so on, are idioms or counterfeits, so the selection of varieties also has certain risks.

4. Technical risk: the seedlings of Bletilla striata generally have to go through the introduction of provenances, and then the roots such as tissue culture seedlings are developed before transplanting, and in this process, because the growth of the rhizome needs the environment of symbiotic bacteria, and the transplanting and management requirements of Bletilla striata are very fine, so the seedling death rate can sometimes reach 50% or higher, so the technical requirements are very high, and the technical risk is not small.

What can be known is that Bletilla striata is currently in great demand in the market, so good planting must be able to bring good economic benefits. But we all know that there are risks in planting and breeding, so we still have to think carefully.
