What is the planting time of Gastrodia elata?

Gastrodia elata is a saprophytic plant, so it appears in Mr. Lu Xun's grass garden, but there are also Gastrodia elata in some other places. If you want to make money from Gastrodia elata, we must make clear the growth characteristics of Gastrodia elata, follow the natural growth law of Gastrodia elata, and the requirements for the natural environment of planting Gastrodia elata.

What are the conditions for planting Gastrodia elata?

Gastrodia elata is born under humus-rich and moist forests, as well as sunny thickets and grassy slopes. It must be symbiotic with Agaricaceae fungus and Osmunda Osmunda in order to make the seeds germinate, form round bulbs and grow into normal Gastrodia elata tubers. Pleurotus ostreatus provided nutrition for seed germination and Armillaria mellea provided nutrition for protococci to grow into Gastrodia elata tubers.

Planting time of Gastrodia elata

Gastrodia elata cultivation is generally from late October of that year to April of the following year. The sowing time is winter planting before soil freezing from late October to early December, and spring planting after soil thawing in March-April, and the sowing time in high-altitude mountain areas can be postponed to May. Gastrodia elata cultivation site can choose any land such as front and back house, wilderness slope land, orchard woodland and so on, especially the sandy loam with strong permeability and water permeability. The pH value of soil is 5-6.

Field management of Gastrodia elata

1. Temperature: the growth of outdoor Gastrodia elata is dominated by natural temperature, and the optimum temperature is 10-26 ℃ in 30 years deep fungus below the soil surface, and other temperatures are dormant. In the soil layer, the short-term low temperature tolerance of Gastrodia elata is based on the weather forecast: outdoor-30 ℃-33 ℃, indoor-10 ℃. Short-term high temperature resistance of 40 degrees. Therefore, in winter, the soil should be covered with a thin layer of weeds or dry leaves, and then covered with a film of more than 20 centimeters of weeds to keep warm and moisturize and prevent freezing. From winter to spring, when the ground temperature is stable above 10 degrees, discard the film and let Rain Water naturally soak and moist. Gastrodia elata planted in spring does not need to be covered with film, but should be covered with grass to shade the sun and moisturize.

2. Moisture: in the disaster year of special drought and waterlogging, if it lasts for more than 20 days, the protection work should be strengthened; it is best to cover the film half an hour after the heavy rain in the waterlogging period, let the water be discharged into the ditch, open the sunny day immediately, preserve soil moisture and drain water, and manage comprehensively. Gastrodia elata entered the physiological mature stage in June, July and August, and the water must be sufficient and dry for more than 15 days in order to obtain high yield.

Moisture should be controlled in September to prevent Armillaria mellea from growing too vigorously and digesting Gastrodia elata into an empty shell to reduce production. It can be excavated and sown at any time from October to the end of April of the following year. 1 square meter Gastrodia elata generally harvests 7 kilograms of fresh Gastrodia elata and 2 kilograms of processed dry hemp, according to the market value of 260 yuan / kg of Anhui Bozhu and state medicinal materials, the income is 520 yuan, and the market value of Kunming medicinal materials is 380 yuan per kilogram, with an income of 760 yuan. At the same time, the first generation of flax seed can be harvested 2 kg, worth 240 yuan, which can be used for planting 3-4 square meters in the second year, 6-8 kg of dry flax in the second year, and 3 times in the third year.

As Gastrodia elata is a variety degraded year by year, it must be changed for 2 to 3 years in order to ensure high yield and high efficiency. Therefore, compared with mining, real estate and contracted projects, the risk of Gastrodia elata is out of the question, but the profit in the second and third year is several times higher than that in the second and third year.

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.

As the environmental requirements of Gastrodia elata are not too high, the planting conditions of Gastrodia elata are not difficult to create, as long as it can be symbiotic with general mushrooms, but the field management of Gastrodia elata is very important, which is an important factor affecting the harvest of Gastrodia elata. So growers need to pay more attention to it.
