Method for propagating radix tetrastigme underground officinal tubers

Abstract

The invention relates to a plant propagation method, and particularly relates to a method for propagating radix tetrastigme underground officinal tubers. The method comprises the following steps of: 1) low-temperature moisture preservation, sand storage and dormancy release; 2) germination acceleration and transplanting; and 3) large field transplanting. According to the invention, the radix tetrastigme underground officinal parts are utilized; through the technologies of low-temperature sand storage, dormancy release, greenhouse germination acceleration and large field transplanting, the radix tetrastigme underground officinal parts root after about 45 days. The method provided by the invention has the advantages of rapid propagation, low cost, high seedling rate, low corrosion rate and the like, thereby breaking through the technical defect that the original radix tetrastigme propagation technology is restricted to overground rattan cottage, which is easy for degradation, instable in variety characteristic, high in tissue culture investment, in need of professionals and the like.

Description

technical field [0001] The invention relates to a method for plant propagation, in particular to a method for propagating part of the underground medicinal tuber of clover. Background technique [0002] Clover (Tetrastigma hemsleyanum Diels et Gilg) is a grape plant, also known as golden thread hanging gourd, silk thread hanging golden bell, three-leaf flat rattan, stone mouse, small flat rattan, stone monkey, Tujing pill, and three-leaf pair. The main production areas are in the southwest of my country and Anhui, Zhejiang, Jiangxi, Fujian, Hubei, Hunan, Guangdong, and Guangxi. At present, there are very few wild resources. The wild reserves in Zhejiang Province are only about 2,000 kilograms, and Clover is demanding on the growth environment. It generally grows in deep mountains and dense forests at an altitude of 700 meters and on the shady side of cliffs. There should be scattered light on it. There must be fine water seeping out, and the leaves below should be covered; ...

Problems solved by technology

[0005] The wild resources of Clover are very scarce at present, and they belong to endangered rare medicinal plants. In the past, the propagation methods of Clover mainly focused on the cutting propagation method of the aerial parts of Ivy clover. Prone to quality degradation

[0006] Clover can be cut through branches, but it must require a lot of female parent resources, and it cannot be in the form of seedlings, otherwise it will easily degenerate. It can also be cultivated through tissue culture, but it requires professional technicians and equipment, and the investment is large. , difficult to promote
