Imitating wildness cultural technique for gastrodia elata

Abstract

The invention relates to an imitative wild cultivation technique of gastrodia, comprising site selection, hollow opening, seed selection, fungus material spread, gastrodia seeds placing, three-grade armillaria mellea placing, humus soil covering and cultivation conducting. The technique results from field study and research, a large number of repeated experiments and explorations in the practice of cultivation by a plurality of years and can stabilize the yield of the gastrodia, particularly improve the quality of the gastrodia cultivation with good appearance and character, close to the wild state. In addition, taking full advantage of the superior natural environment, the technique reduces drop in production caused by bacteria invading, improves the capacity of the gastrodia to combat natural adversities, reduces cost by getting materials from local resources and makes up for the shortage of large field cultivation so as to resolve the land contention with the farmland, promoting the development of the special industry of underwood planting of the ecological agriculture.

Description

technical field [0001] The invention relates to a cultivation method of gastrodia elata, a traditional Chinese medicinal material, in particular to an imitation wild cultivation technique of gastrodia elata. Background technique [0002] Gastrodia elata belongs to Orchidaceae, a perennial symbiotic herb. Mature plants have tubers and flower stems, without roots and leaves. The tubers are fleshy, light yellow, long ovate or oblong, 7-15 cm long, with uniform links and membranous scale leaves at the nodes. The flower stems are erect, 1-1.7 meters high, the racemes are terminal, and the flowers are light orange-red or yellow-green. Capsule oblong or obovate. The flowering period is from June to July, and the fruiting period is from July to August. Born in forest gaps or forest edges at an altitude of 400-3200 meters. Mainly distributed in Sichuan, Yunnan, Shaanxi, Guizhou, Hubei, Hunan, Anhui, Henan, Gansu, Jilin, Taiwan and Tibet. It is also distributed in India, Bhutan,...

Problems solved by technology

On the surface, this cultivation method is convenient for centralized management and can also increase production. In fact, it has many disadvantages: 1. Weak ability to resist natural disasters, such as drought and waterlogging, resulting in increased labor

2. Due to the impact of hygienic conditions in front of and behind the house, Gastrodia elata is vulnerable to pests and diseases, resulting in a reduction in production of Gastrodia elata

3. In the process of material preparation, due to factors such as handling fungi and centralized planting, the cost increases

4. Due to the absence of a good natural regulation environment, the temperature and humidity during the growth process of Gastrodia elata are greatly affected, resulting in uneven growth speed of Gastrodia elata, and it is difficult to guarantee the quality of Gastrodia elata
