Gastrodia tuber imitative wild sexual reproduction breeding technique

Abstract

The invention discloses an imitative wild sexual reproduction and breeding technique of gastrodia tuber. Main steps comprises that breeding is carried out to get mature gastrodia tuber seeds and good sprouting strain, mature class III shoestring fungus is adopted as production seed, which is planted under a natural hillside forest that is with over 80 percent of shade density and in which wild gastrodia tuber grows and is distributed; artificial mixed germination strain is adopted; room temperature is controlled so as to produce germination strain with seed; sexual reproduction, breeding and planting time is selected between June and August; the breeding technique is also suitable for field breeding. The invention has the advantages that: 1. bad factors resistance property of sexual reproduction and breeding of gastrodia tuber is improved. 2. Gastrodia tuber seeds are germinated to lead the growth cycle of protocorms to be a time slice that is basically matched with an animated period of the shoestring fungus; inoculation rate and survival rate of the protocorms are increased. 3. Raw materials are obtained locally, thus reducing cost; sustainable development of non-pollution gastrodia tuber planting industry is promoted in ecological agriculture forests. 4. The small site breeding method enhances competitor infection resistance of the gastrodia tuber seed.

Description

technical field [0001] The invention relates to a breeding technology of traditional Chinese medicinal plants, in particular to the technology of sexual breeding 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, Nepal, Korea, Japan and t...

Problems solved by technology

[0007] The purpose of the present invention is to seek a kind of Gastrodia elata sexual reproduction technology, meet the large-scale production requirements, solve the problem that the quality of artificial gastrodia elata is worse than wild gastrodia elata simultaneously, make the quality of artificially cultivated gastrodia elata consistent with wild gastrodia elata. The growth of Gastrodia elata species in the wild natural state of the woodland, while shortening the growth time, the applicant achieved this goal through repeated practice and research
