What are the reasons for the poor harvest of Gastrodia elata
Under normal circumstances, if the growth conditions of Gastrodia elata are satisfied, high yield should be obtained, but sometimes the harvest is poor, which is mainly caused by the degradation caused by asexual reproduction of Gastrodia elata. After several generations of asexual reproduction, the reproduction coefficient and weight gain rate of Gastrodia elata were greatly reduced.
In order to prevent the occurrence of this phenomenon, so that Gastrodia elata can continue to produce high yield, so it is necessary to engage in sexual reproduction.
In addition, the degradation of Armillaria mellea can also lead to poor harvest of Gastrodia elata. At present, the degradation of Armillaria mellea is serious in some flax planting areas. If it is not solved, it does affect the yield and efficacy of Gastrodia elata. Therefore, excellent strains of Armillaria mellea should be introduced, or the roots of wild Armillaria mellea and vetch should be used to cultivate high-quality sticks, so as to prevent the yield and failure of Gastrodia elata.

Several control methods of mushroom diseases and insect pests
First, mushroom brown rot: also known as mushroom verrucosporium, vesicle disease, white rot and so on. It is the most harmful disease in mushroom cultivation at present. In addition to harming mushrooms, it can also harm Pleurotus ostreatus, straw mushrooms, Tremella fuciformis and Ganoderma lucidum. The symptoms of the disease are different in different stages of mushroom development. when the mushroom begins to kink to form a young mushroom bud (when the fruiting body is not differentiated), it is easy to be infected and form a hard horse-like irregular tissue mass. It was covered with a layer of white villous hyphae, then darkened, and finally turned dark brown, oozing dark brown droplets from the diseased tissue. The small mushroom buds under the covered soil are also

How to cultivate Gastrodia elata in the trough on the indoor bed frame
① bed frame setting: it is basically the same as the bed frame for cultivating mushrooms, with a width of 1.2m, a height of 2.5m and a length of 5.5m. The lowest layer can be cultivated on the ground, using pit-type double-layer flax planting method. The spacing of each layer of the bed frame is 60 cm, and it can be planted with 5 or 6 layers. You can build it with an iron frame or a wooden pole, as long as it is strong and durable. Use wood and bark at the bottom of each bed (it is best not to use pine wood, if you can't find the wood of broad-leaved trees, you can also use pine wood instead), wide slats and so on. If there is no plank, use bamboo
