Let's go and know more about it with the editor.

How to grow Gastrodia elata

1. Planting time and site selection. The mountain area is suitable for 300-1800-2600 meters above sea level. Low-altitude areas such as basins and plains are required to be indoors, shade sheds, basements, caves and other places that can shade and cool down.

2. Build a bed. Indoor flat ground cultivation can be made of bricks or boards divided into border ponds with a width of 80 cm, a height of 20 cm and unlimited length. We are shooting and editing the latest full set of technical videos of indoor box cultivation of Gastrodia elata. Please pay attention.

Field or mountain slope border, dig 10 cm deep, 80 cm wide, unlimited length, conducive to operation, border and border spacing of 50 cm, easy to dig drainage ditch and walk.

3. Sowing and cultivation. At the bottom of the border, the pine leaves are 5 cm thick, and the thick sticks are placed one by one at an interval of about two centimeters, either horizontally or horizontally, with the cut facing up, fill the sand until the surface of the thick rod is flat, but can not cover the surface of the thick stick, spray water until the sand is drenched, sprinkle a thin layer of leaves to cover the thick stick, sow branch fungus, each seed interval is 6 cm, order hemp seed, each flax seed interval is 10 cm Put a thick rod with a diameter of about 5 cm at an interval of 40-50 cm, spread loose hair to the surface of the rod, do not press it, and require looseness. The rod is covered with twigs and forks about 3-5 cm thick, and the cover soil is about 15 cm thick. The branches can be breathable if they are opened.

Cultivation techniques of Gastrodia elata

1. Selecting and raising seedling sites

Select loam or sandy loam with good moisture permeability and good permeability, loose and rich in humus, and dig holes with a depth of 35 cm and a width of 85 cm. When choosing a land, it is better to choose a wasteland. Soil pH5-6 is suitable. Avoid clay and waterlogged waterlogged land, avoid stubble. In addition, Gastrodia elata can be planted in air-raid shelters, caves, basements and other places.

2. Cultivate bacteria bed

Armillaria mellea or fungus bed should be cultivated before planting Gastrodia elata. General broad-leaved trees can be used as materials for cultivating Armillaria mellea, but mistletoe, oak, chestnut, cork oak and other tree species are better.

3. Seed treatment

Seed selection: select the Gastrodia elata dug up in that year, remove the commercial hemp, select and screen all the flax species, and get rid of rotten hemp, deformed hemp and other inferior hemp species. Finally, Gastrodia elata, which is similar in size, strong, neat in appearance, large in size, good in color and non-invasive, is determined to be used in the following year.

4. Seed propagation

Choose Gastrodia elata with a weight of more than 100 grams, plant with picking, prevent sunlight when heading, and carry out artificial pollination when flowering. The time of pollination can be chosen at about 10:00 on a sunny day, when the edge of the cap appears slightly. Cover the ear with a plastic bag after pollination.

Post-planting management

After planting, Gastrodia elata does not need to apply fertilizer, do not need to loosen the soil and weed, and keep it wild. The soil water content should be kept at about 40% and the ground temperature should be kept at 15-28 degrees. Spraying Gandaling solution on the leaf surface during the rhizome expansion period can promote the transport of foliar photosynthetic products (nutrients) to the root system, improve the nutrient conversion rate and the ability of loosening soil, make the rhizome expand rapidly, and the content of effective substances is greatly increased. Sunshade net or branches should be used to shade and cool down in summer high temperature season to prevent people and animals from trampling. In case of drought, you can water it appropriately. At the same time, pay attention to prevent stagnant water during the rainy season. Before overwintering, it is necessary to thicken the soil and cover the leaves against freezing; during the high temperature period from June to August, we should build a shed or intercropping tall stalk crops to shade, clean up the drainage ditch before the rainy season, and remove stagnant water in time to prevent tubers from rotting. In spring and autumn, you should receive the necessary sunlight to maintain a certain temperature.
