Method for asexually and rapidly breeding gastrodia elata in karst cave

Abstract

The invention discloses a method for asexually and rapidly breeding gastrodia elata in a karst cave, and belongs to the technical field of gastrodia elata planting. The method comprises the followingsteps of (1) site selection, specifically, selecting a karst cave with the altitude of 320-1534 m and the gentle terrain; (2) constructing a fungus bed, and placing and fixing a fungus bed standard box according to the terrain in the karst cave; (3) wood selection and treatment, specifically, selecting cedarwood, paulownia and sophora japonica wood sections, forming axial holes in the axial direction of the wood sections, and placing the wood sections in a standard box of the fixed bacteria bed at equal intervals; (4) box-type cultivation, specifically, preparing a standard box filling material, and mixing river sand, humus soil and saw dust according to a mass fraction ratio of 1: 3: (4-6); and filling gaps with a filling material, placing armillaria mellea branches and short branches ontwo sides and two ends of the fungus material, filling and leveling up the fungus material with the filling material, placing gastrodia elata seeds, covering the gastrodia elata seeds with soil for 8-15 cm, and placing a second layer according to the method. The method disclosed by the invention is high in practicability, and the problems that the difference between the cultivation temperature andhumidity of the gastrodia elata in the forest changes greatly along with four seasons, the breeding period is long, and large-scale and industrial development of the gastrodia elata is not facilitated are effectively solved.

Description

technical field [0001] The invention relates to the technical field of Gastrodia elata planting, in particular to a method for rapidly asexually breeding Gastrodia elata in a karst cave. Background technique [0002] Gastrodia elata is a perennial herbaceous parasite of Orchidaceae. It is a precious Chinese medicinal material. With the improvement of people's living standards and the increase of health awareness, Gastrodia elata products have developed from a single medicinal use in the past to diet and nourishing health care industries. The popularity and love of consumers has broad development space and market prospects; but at present, Gastrodia elata breeding is mainly based on forest cultivation, and there are large differences in the humidity and temperature of breeding with the four seasons, and the dormancy time of hemp seeds is long, and the breeding cycle is long. Thereby limiting the problem of large-scale and industrialized development of Gastrodia elata. Conte...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a method for rapid asexual breeding of Gastrodia elata in karst caves, which effectively solves the problem of large differences in humidity and temperature in the cultivation of Gastrodia elata in the existing forests with four seasons, long dormancy time of hemp seeds, and long breeding cycle. long, which limits the scale and industrialization of Gastrodia elata
