Gastrodia likes a cool and humid climate, but it is afraid of freezing, high temperature and stagnant water. The growth cycle of gastrodia elata is about 3 years, and its growth goes through four stages: seed germination, primary bulb, primary bulb and secondary bulb. Planting gastrodia elata is different from planting other medicinal materials, and the initial investment is relatively large, especially in the first year, the land should be rectified first.

First, the growth environment and cycle of Gastrodia elata

Gastrodia elata likes cool and humid environment, but it is afraid of freezing, high temperature and water accumulation. When planting gastrodia elata, we must pay attention to the growth environment, and the environment is suitable to grow better.

2. The growth cycle of Gastrodia elata is about 3 years. Its growth process goes through four stages: seed germination, primary bulb and secondary bulb. It takes about 60-70 days for gastrodia elata to germinate from flower stem to seed maturity, and 20-2 1 day for fruit development.

3. Gastrodia elata is different from other medicinal materials, and the initial investment cost is relatively high, especially in the first year. Before planting gastrodia elata, the land should be rectified, and the price of seeds is relatively expensive, about 50 thousand yuan. If labor costs and wooden sticks are added, it will cost about 7000-65438+ 10,000 yuan per mu in the first year.

Second, the planting method and steps of Gastrodia elata.

1. Planting: Since Gastrodia elata cannot be directly planted, it is necessary to cultivate auricularia auricula. First of all, we should choose high-quality Armillaria mellea and a piece of wood with a diameter of about 10 cm and a length of about 70 cm, make a small mouth at every 15 cm of the wood, then inoculate auricularia auricula, keep the temperature at about 15℃ and mature in about 3 months.

2. Soil: loose sandy soil can be selected for planting gastrodia elata, and the soil pH value should be around 5.5, which must be uncultivated wasteland. When planting, a border can be built on the flat ground, with a width of about 70-90 cm and a depth of 8- 12 cm.

3. Seed selection: When selecting seeds, you must choose white hemp varieties, eliminate rotten and moth-eaten inferior seeds, and then choose seeds with good appearance, health and integrity. Each seed weighs about 40 grams.

4. Burying firewood: first spread a layer of leaves on the border, and then put the cultivated fungus horizontally with a spacing of about 2 cm. Then sprinkle a layer of sand on the fungus material, which can't completely cover the fungus material. Finally, sprinkle water and sprinkle the seeds in (the spacing is about 10 cm).

5. Management: Gastrodia elata must be well managed during its growth. You can build a sunshade for gastrodia elata in hot weather. It's cold, so you must spread a layer of leaves on gastrodia elata and cover it with a film to keep warm.
