The planting season of Gastrodia elata

The growth of crops has certain growth rules, and planting Gastrodia elata is no exception. A good living environment can help the roots of Gastrodia elata grow stronger, so that growers can get a better harvest. So the editor is here to provide you with some information related to the growth of Gastrodia elata, just for your reference.

The planting season of Gastrodia elata

The cultivation of Gastrodia elata is the same as many crops. It also has its own growth rules and seasons. The general planting time of Gastrodia elata is from November to March of the following year. But the growth of Gastrodia elata is between April and October in the Gregorian calendar, and the growth time is about six months.

Planting 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

① seed selection: select the Gastrodia elata dug up in that year, remove the commercial hemp, select and screen all the flax species, pick out rotten hemp, deformed hemp and other inferior hemp species, and finally determine Gastrodia elata, which is of the same size, strong, neat appearance, large size, good color and non-invasive, as the hemp seed used in the following year.

② seed dressing: seed dressing with 10-50 times solution of new high lipid membrane to prevent the invasion of diseases. The bottom of the pit will be dug loose, leveled and covered with a layer of broad-leaved tree leaves and humus soil, and then the prepared wood will be evenly placed at the bottom of the pit, with a distance of 6-8 cm and 6-8 pieces of wood in each nest. When planting, put the Armillaria mellea branch close to the fish scale on both sides of the wood, and then put the Gastrodia elata seeds on the fungus branch and wood, so that the two can quickly establish a nutritional symbiosis relationship. After that, the remaining strains of Armillaria mellea were divided into soybean-sized particles and scattered evenly in the middle of the wood. Then fill it with humus or fine sand and press it gently, leaving no space. If there are a large number of seeds, strains and branches, you can cultivate another layer above the first layer, the method is the same as above. But pay attention to the upper and lower wood into a "well" shape. Finally, it is covered with about 15 cm of fine soil, covered with dead branches and leaves, and the adult turtle is back-shaped, slightly above the ground to facilitate drainage.

4. 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.

5. Harvesting and processing

It is usually excavated from October to November in spring and autumn. After digging up, wash the sand and the bacterial cord on the surface of Gastrodia elata with rice washing water, then put the steamer and steam for 10-25 minutes, depending on the size of Gastrodia elata. Steam and dry directly, pay attention to prevent mildew in cloudy and rainy days.

Planting prospect of Gastrodia elata

The market price of Gastrodia elata is very stable and has a good planting prospect. Artificial cultivation of Gastrodia elata is not technically difficult. Ordinary crops are sown directly in the soil and grow on fertilizer in the soil, while many growers hear that Gastrodia elata is nourished by Armillaria mellea and uses wood as nutrients. I think it's very complicated to grow Gastrodia elata.

The origin of Gastrodia elata

The producing area of Gastrodia elata is distributed in tropical, subtropical, temperate and cold temperate mountains. It ranges from New Zealand and New Caledonia in the east to Madagascar in the west. It extends from Australia and New Zealand to the north to the northeast of China and the far East of the former Soviet Union. Mainly include China, India, Thailand, Bhutan, Nepal, Japan, Sri Lanka, Madagascar, Australia, New Zealand, China once belonged to the Ryukyu Islands, Ogasawara Islands, Kalimantan Island, Malaysia's Malay Peninsula, New Caledonia Island, as well as North Korea, the Philippines, the Russian far East Amur, coastal border areas, dry islands and other areas. The plant was not found on the African continent, Europe and America.

The planting difficulty of Gastrodia elata is relatively low in the cultivation of most medicinal materials, the current market price of Gastrodia elata is relatively stable, and the market prospect is relatively good, so as long as growers can grasp the growth law of Gastrodia elata well, generally speaking, they can get better income if they do the right thing at the right time.
