Planting technique of Gastrodia elata

Gastrodia elata is a kind of traditional Chinese medicine, the main part of which is its rhizome. Gastrodia elata has a high status in traditional Chinese medicine in China, and has a strong efficacy, which can be used to treat hypertension, limb numbness and other problems. However, it is troublesome to grow Gastrodia elata, because the annual output is not very high. So how to grow Gastrodia elata? The following editor brings you the planting technology of Gastrodia elata, let's have a look!

1. Material preparation

Gastrodia elata is a kind of fungal medicine, so we should first prepare wood when we plant it. The wood specification should be controlled at 5-15 cm in diameter and about 55 cm in length, and the number of wood roots should be controlled according to the number of trees planted. Then make 4-5 slopes on each piece of wood. Then prepare a certain amount of twigs, fallen leaves and pine hairs. Soak larch hairs in water to soften them before planting. Then choose a soil that has not been planted, and if there is, turn it about 35 centimeters deep. Then prepare Armillaria mellea, divide it into separate individuals for planting, and finally select Gastrodia elata species.

2. Choose a place to make a bed

The planting plot of Gastrodia elata should be selected at an altitude of about 500-2500 meters above sea level. If the terrain is low, then it is best to use greenhouse cultivation to do a good job of shading. Then plan the planting area in the greenhouse, straighten out the border pool, and the specification of each border pool is controlled at about 85cm in width and 25cm in height to ensure that Gastrodia elata has sufficient space for growth. If it is cultivated on an open hillside, it is necessary to dig a pit about 12 cm deep and 85 cm wide in the ground to facilitate later operation and management. Then leave a certain distance between the beds, dig a good drainage ditch, and do a good job of pedestrian passage.

3. Sowing seeds at the right time

First of all, lay about 6 centimeters of larch hair at the bottom of the border, and then arrange the wood, with an interval of about 3 centimeters, and put the slant upward. Then put the sand in it and keep it level with the wood. Pour enough water, sprinkle a layer of leaves on the sand to cover the wood, and then sow the seeds. Pay attention to control the sowing density, and then put a piece of wood at a distance of about 45 centimeters, spread a layer of pine hair on it, keep it level with the wood surface and keep it transparent. Then cover the twigs and cover the border pit. After sowing, water is watered once, and then some sandy soil is sprinkled properly to improve the heat preservation capacity of the soil.

4. Key points of management

Gastrodia elata cultivated in open field is dominated by natural temperature, and the best temperature should be about 15 degrees under the soil. The low temperature tolerance of Gastrodia elata is relatively poor, so in winter we should pay attention to cover a layer of straw and then cover branches and grasses to improve the heat preservation ability. When the spring temperature gradually rises to about 10 degrees, uncover the plastic film to promote water absorption. If you encounter a long period of drought, then you must do a good job of watering in time. And if you encounter heavy rain, then it is necessary to cover the film in time to prevent stagnant water and drain through the gutter.

The above is a brief introduction of Gastrodia elata planting technology, Gastrodia elata planting operation is more troublesome. There are certain requirements for planting technology, so we should not plant blindly! That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
