Can diammonium phosphate, calcium superphosphate and ammonium nitrate be applied to cultivated Gastrodia elata? How to apply
It can be used. Because these three kinds of chemical fertilizers are all acidic fertilizers, they can increase the acidity of the soil. In terms of properties, it is suitable for the requirements of the growth and development of Armillaria mellea and Gastrodia elata; in terms of composition, these three kinds of fertilizers all contain phosphorus and nitrogen; theoretically, Armillaria mellea needs a certain amount of phosphorus and nitrogen in the process of growth and development. In the process of growth and development, Gastrodia elata can absorb some trace elements and phosphorus with the water in the matrix, so the yield of Gastrodia elata can be increased by applying appropriate amount of acidic chemical fertilizer. According to Danfeng County, Shanxi Province, Siping Township Wangjiayuan Village Tianma professional households, Wang Yingkui test: each nest (10 square meters) Gastrodia elata application of 0.5 kilogram ammonium nitrate, can increase the yield by 10% and 20%. The method is: in the bottom of the nest or cellar, dig loose the bottom soil, evenly sprinkle fertilizer, stir evenly, and then sprinkle 1 cm thick sandy loam. Then put the bacteria stick and strain at an interval of 3 centimeters, and pick up and press them repeatedly to compact the soil under the bacteria stick and strain. Then rely on bacteria to cultivate Gastrodia elata, fill the gap with sandy loam and cover the soil with 3 cm. Finish the second layer with the same method and cover the soil with 15 cm.

Planting method of Gastrodia elata
① asexual propagation cultivation method using tubers of Gastrodia elata as reproductive material is called asexual cultivation. ② active fungus material plus new material companion planting method digs the kiln according to the specific conditions of the planting site, the kiln width is 6ml 8cm wider than the length of the fungus, and the length of the kiln is variable, so it is appropriate to release 20 pieces of fungus; the depth of the kiln should be adjusted to local conditions, the bottom of the kiln should be dug into a slope shape, and then the fungus can be laid and Gastrodia elata can be planted. ③ sexual reproduction method the planting method of using seeds as reproductive material is called sexual reproduction cultivation. Produced by seed reproduction.

Cement combination box for cultivation of Gastrodia elata
The box is completely composed of cement board, and the volume of the cavity is required to be 60 cm long, 40 cm wide and 32 cm high. Each box is composed of five plates, of which two horizontal sides are 60 cm long, 32 cm wide and 2 cm thick, two plugs are 45 cm long, 32 cm wide and 2 cm thick, and a bottom plate is 65 cm long, 45 cm wide and 3 cm-5 cm thick. The plate and the plate are connected by a connecting ring, which is interlaced with canine teeth, and a pin stick is inserted into the ring. 1. Backplane. The open-box cow bears the most load.
