Some points for attention in the introduction of Gastrodia elata

1. Suitable conditions: Gastrodia elata has no roots and leaves, can not carry out photosynthesis, and relies on the supply of Armillaria mellea for vegetative growth and reproduction. Therefore, the first step of planting Gastrodia elata is to cultivate a certain number of high-quality Armillaria mellea, and the second step is to introduce and purchase Gastrodia elata species. And planted with Armillaria mellea in time.

Second, the adaptability of the hybrid Gastrodia elata of "Wu X Hong" and "Hong X Wu" is stronger than that of traditional asexual reproduction, and it is suitable to be planted in all potato planting areas, and its method is as extensive and simple as planting potato. Do not compete with crops for land, fertilizer and labor.

Third, the suitable temperature for the growth of Gastrodia elata is 10Mel 30 ℃, the optimum temperature is 20Mel 25 ℃, the air relative humidity is about 80%, the soil water content is 50% Mel 55%, and the pH value is 5 Mel 6, that is, the slightly acidic ecological environment.

4. the suitable planting time is outdoor planting in winter (from January to January of the following year) or spring planting (from March to May). The one-step method of box planting Gastrodia elata, which is the patented technology used in indoor, cave and civil air defense fortifications, can be planted without soil every year. After sowing, supplemented by artificial temperature control and humidification measures, it can be harvested after 180 days of closed management.

Fifth, the cultivation of Armillaria mellea can be carried out year-round. Generally, high-quality Armillaria mellea test-tube mother species are purchased 90 days before Gastrodia elata sowing, and then propagated and transplanted into Armillaria mellea material. The technological process is as follows: mother seed (grade 1) → original seed (grade 2 species) → cultivation species (grade 3 species) → Armillaria mellea material (growth medium for Gastrodia elata), and then purchase hybrid Gastrodia elata seeds for co-planting. High-quality Armillaria mellea cultivation can also be purchased 40 days in advance, because the cultivation of Armillaria mellea can be fully open operation, no technical difficulty.

The most reliable way to sell Gastrodia elata is to sell itself nearby or hand it over to the local medicine purchasing department. The first introduction should inspect the market situation and demand of medicinal materials on the spot so as to avoid economic losses caused by sales obstruction.
