Cuttage seedling culture method for root tuber early-growing of tetrastigma hemsleyanum

Abstract

The invention relates to a cuttage seedling culture method for root tuber early-growing of tetrastigma hemsleyanum. The method comprises the six steps: (1) selecting a local high-quality tetrastigma hemsleyanum variety; (2) determining a cuttage period; (3) collecting and treating cutting slips; (4) carrying out soil preparation and cuttage; (5) building a greenhouse and controlling light; (6) carrying out seedling stage management, which comprises the six substeps of watering, carrying out foliage application, weeding, carrying out new vine length fixing, carrying out pre-transplanting training and carrying out timely transplanting. After seedlings are cultured for 5-6 months by using the method, during transplanting, the ratio of the seedlings, of which the roots grow root tubers, reaches up to 75%, and the ratio of the seedlings with the root tubers is greatly increased; after the seedlings are cultured for 3-5 years, during harvesting, the root tubers are large and numerous, so that the grade and yield of the medicinal material are increased, tetrastigma hemsleyanum, namely a valuable medicinal material, of which wild collection is increasingly scarce can be effectively supplemented, a new technical scheme is provided for a newly-domesticated tetrastigma hemsleyanum seedling culture technology, and thus, the method has certain social and economic benefits.

Description

technical field [0001] The invention relates to a method for cultivating medicinal plants, in particular to a method for growing seedlings by cuttings of cloverleaf which is beneficial to early caking roots. Background technique [0002] Clover, common name is 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, three-leaf peer, etc., and its scientific name is Tetrastigna hemsleyanum Diels et Gilg), is a perennial herbaceous vine of the genus Cliffaceae in the family Vitis genus. The whole plant has medicinal value, especially the underground tuber (called snake aconite in medicine) has the best medicinal effect, and it is mostly used fresh or dried. [0003] The medicinal value of clover was first seen in "Compendium of Materia Medica": "Cliff clover, cool in nature, bitter, pungent, clearing away heat and detoxification, promoting blood circulation and expelling wind"...

AI Technical Summary

Problems solved by technology

[0004] At present, the demand for clover in the market is increasing, and relying solely on wild mining is far from being able to meet the demand. As a result, the price of clover remains high. In recent years, the increase has been relatively large, and there is a further upward trend

Clover has poor regeneration ability in the natural environment, and the structure of the associated plant community is complex. In recent years, as wild resources have suffered more and more serious human damage, its wild distribution has become more and more narrow, and the resource reserves have decreased sharply. Collecting, preserving and breeding its resources may lead to extinction

There are a lot of studies on tissue culture and rapid propagation of Clover, but there is insufficient research on cutting seedlings and artificial cultivation. There are only sporadic and unsystematic experience reports. It is necessary to add new experience to this newly raised technology treasure house. , forming a mature technical system

CN104255218A and CN104186141A disclose the bag type cultivation method of bionic interplanting of Clover in forest land, each contributes to the domestication and cultivation technology of Clover, so far there is no effective method of cutting many roots of Clover at the seedling stage and promoting high yield Reporting of method and emergence of model land

[0006] To sum up, there is a huge gap in the investigation of Clover resources and research on cultivation and breeding. There are also many problems to be solved in production. The more prominent ones are: in the process of artificial domestication and planting of Clover, many asexual reproduction Seedlings do not form the main medicinal organ—the underground tuber, commonly known as "non-balling", or the underground tuber "balling" is very small, growing slowly, and low yield. This is a common problem faced by growers. "ball", the output and benefits are greatly affected, unable to meet the market and medicinal needs

The artificial cultivation of the wild medicinal plant Clover has started in recent years, and the actors are doing their own things. There are no reports of complete and effective cutting and cultivation experience.
