Cultivation methods of Gastrodia elata

Gastrodia elata belongs to herbaceous plant, which is used as medicine in underground tuber. it mainly treats hypertension, vertigo, headache, askew of mouth and eye, limb numbness, infantile convulsion, hemiplegia and other diseases. it is also used in pilots' brain health care and Alzheimer's disease. it is an ideal brain nerve health care medicine.

1. Reproduction of Gastrodia elata 1.1 sexual reproduction when a small number of Gastrodia elata extract stems from the ground and blossom, they should keep the sandy soil moist, fix the stems with bamboo poles and shield them from the sun. After the buds are formed, one to several flowers will bloom from bottom to top every day. If there is a lack of pollination insects can also raise bees nearby or carry out artificial pollination, use tweezers to open the Corolla, remove the anther cap, take out the powder block and place it on the stigma. The time of pollination should be from 10:00 to 4 p.m. When pollination is successful, the ovary expands, the Corolla withered, and the ovary has obvious stitches. Once the ovary is cracked, a large number of seeds will be raised. When a fruit is cracked, five adjacent fruits will be cut off and placed in a vessel to be naturally cracked. Seeds scattered in utensils are sown immediately and cannot be placed. Lift up the fungus material of the cultivated fungus bed, spread broad-leaved leaves with a thickness of about 1cm below, sow seeds between leaf layers, sow seeds with 20 fruits per square meter, then restore the fungus powder to its original state, scatter a layer of leaves and cover it with cover, so that it can grow into a strong Gastrodia elata and become a high-yielding hybrid. When planting Gastrodia elata, make a few more bacterial beds, do not put pockmarked seeds, and prepare to pick Gastrodia elata for sexual reproduction. 1.2 asexual reproduction from October to November, ground temperature 5 ℃ 6 ℃, Armillaria mellea can grow, but Gastrodia elata needs about 10 min to germinate, so it takes a long time for Gastrodia elata planted in autumn and winter, Armillaria mellea and flax seeds combine to get sufficient nutrition supply when Gastrodia elata begins to germinate in the coming year. Therefore, autumn planting is the best season. The methods are as follows: (1) choose humus black sandy soil to dig the cellar, filter the water and keep warm in the mountain area or dig the cellar in the courtyard, 25-30cm in depth and 50-60cm in width. The pit bottom has a slope of 10 °- 15 °along the mountain to facilitate the passage of water. (2) to prepare the backfill, use the black loose soil of the mountain broad-leaved forest (Chai Laodi) as the backfill; you can also choose the fat and black mud on the flat ground plus sawdust, or the sundries after sifting out the soybeans when the soil is added to the rice husk or beating soybeans, and those under the sieve are bagged for use, and those above the sieve are broken for use. When harvesting the potato, the rattan is cut and dried, the feed machine is broken, and transported to the planting site and sand to mix and prepare. The ratio of sawdust to sandy soil is 3:1 (volume ratio), the ratio of leaves (unrotten crushed) plus mud and sandy soil, and the ratio of rice husk (or salt bean vine, jasmine vine) to Gaza is 2VR 1, which is covered with a layer of fine sand to cover the litter. In order to promote the growth and development of Armillaria mellea, one-time application of phosphate fertilizer, that is, 0.5% ml 1% potassium dihydrogen phosphate aqueous solution or according to a layer of calcium superphosphate powder, the dosage per cellar is 20ml 30g, weighing the sample, ready to spread. (3) the discharge of bacterial sticks should first sprinkle 5-6cm deep mixed mud at the bottom of the pit, and then sprinkle a layer of semi-rotten broad-leaved leaves (not too thick), so as to cover the soil. First, put 4 bacterial rods along the hillside, the distance between the rods and the rods is 2-3cm, the middle of the two rods is close to the rods, the growth points of the two ends are outward, the head of the rods are put 2 hemp seeds, put the back cover mixed soil to the rod flat, and then put a layer of bacterial sticks and hemp seeds, with soil to fill the gap. When swinging, the upper and lower rods should be staggered, the first layer should be placed, and then the 5cm mixed soil should be placed, and then the second layer of bacterial sticks and hemp seeds should be placed. Cover with a layer of leaves, and finally cover with 7-10cm and horizon. (4) the cultivation method of adding firewood can not only establish a Republican relationship between Gastrodia elata and Armillaria mellea, but also provide rich nutrition for Armillaria mellea. During cultivation, flax seeds should be placed close to bacterial sticks and filled with leaves. (5) in the method of bacterial bed cultivation, the cellar was dug when the countryside was free from May to June, and firewood and salary sticks were put in. When planting, dig up the bacterial bed, first dig out the upper bacterial stick, do not move the lower rod, just shovel a small hole in the middle of the lower rod, put it into the hemp seed, then put the upper rod in the same place (don't mess up the original stick), put the flax seed by the tight bacterial stick, sprinkle 20g calcium superphosphate, fill the gap soil and cover the soil on the flat ground, this method can pick up the bacteria block, the inoculation rate is high, and the yield is also high. (6) the three-pronged cultivation method is to use artificially cultivated pure Armillaria mellea, aseptic fresh sticks and flax seeds to go to the cellar at the same time, the general amount of bacteria is 8mur9 kilograms / square meter, seed hemp 1.5 kg (3 cellar / square meter). 2. After cultivation, the seed hemp will go down to the cellar from October to November, and the grass will be hoed once from April to May next year to prevent people and animals from trampling. The main results are as follows: (1) Gastrodia elata has just developed and grown in drought prevention spring, and its water demand is low, and its growth period is from June to August. Attention should be paid to watering and protecting buds in case of drought, because young buds are easy to dry up and die because they can not adapt to adversity. A small hole can be dug gently with a hoe at the upper end of the cellar, then watered and infiltrated, and restored to its original state after pouring. Flat ground can be watered around the cellar to infiltrate, set up frames at the same time, plant melons and fruits, and let the branches shade the sun. (2) to prevent waterlogging and dig drainage ditches. (3) Anti-freezing cover weeds or thick cover leaves.
