What are the characteristics of artificially cultivated Gastrodia elata
(1) small investment. Generally speaking, the total expenditure in that year (per square meter) is 27,28 yuan, while the expenditure in the second year is only about 4 yuan, because there is no need to buy hemp seeds and batch strains in the second year. If it is green bark tussah and other hard miscellaneous wood, can be cultivated for 3 years, cork can also be used for more than 2 years. Polyporus umbellatus can also be cultivated with old fungus materials in order to achieve comprehensive utilization and improve economic benefits.
(2) the effect is quick. It takes 8 to 10 months indoors and only 1 year to harvest outdoors with white hemp as seed.
(3) material saving. In the past, artificial cultivation of Gastrodia elata used large wood as fungus material, which was wasted greatly. In the case of tight wood, Gastrodia elata can be cultivated with branches. According to the experiment in Ningqiang County, Shaanxi Province, using twigs of 2 cm in diameter as bacterial material has the advantages of saving wood, reducing cost, receiving bacteria quickly, short culture time, high nutrition utilization rate, remarkable economic benefit and so on.
(4) the income is large. In general, every square meter of Gastrodia elata can receive 512 kg per year, up to more than 15 kg, equivalent to RMB 100,240 yuan, the economic benefit is very considerable.
(5) the operation is simple and the management is convenient. As long as we master the technology, after planting Gastrodia elata, we do not need weeding or fertilization, mainly to prevent drought, cold, high temperature, waterlogging and soil moisture conservation, and do not have to spend too much labor.

A simple and rapid method of producing bacteria in Pleurotus ostreatus production bag
Bag cultivation of Pleurotus ostreatus usually takes 25 to 30 days after inoculation before the mycelium can fill the bag. The longer the time of infection, the greater the probability of infection of miscellaneous bacteria, and the longer the production cycle. In order to shorten the time of collecting bacteria and improve the economic benefit, this paper introduces a simple method of rapid bacteria distribution in Pleurotus ostreatus production bag. In the center of the two ends of the Pleurotus ostreatus bag, the hole is punched with a sharp rod with a diameter of 2 cm to 3 cm and a length of 30 cm, and the depth of the hole is more than half of that of the bag. Then put an appropriate amount of bacteria into the rod hole, and put more than the conventional inoculation amount on the material surface at the end of the bag.

What are the technical elements of artificially cultivated Gastrodia elata
(1) change the wild into home planting. (2) adopt single-layer and double-layer cultivation, and further develop into three-layer cultivation. (3) the covering material was added to the upper and lower layers by the method of co-planting with bacterial material, so that the fungal cord grew both upward and downward, and the middle fungal cord was interwoven into a network, which was more beneficial to the growth of Gastrodia elata. (4) when using big branches as fungus material, we should pay attention to using small branches, which not only saves wood, but also facilitates local use of materials in plain areas and makes full use of raw materials. (5) cultivation in wooden boxes and brick ponds
