Clematis root cutting vegetative propagation method

Abstract

The invention discloses a clematis root cutting vegetative propagation method. The method includes following steps: collecting cuttings; preparing a cutting seedling bed, using a carbendazim lotion of 0.2% in concentration to spray and disinfect the matrix, and filling a seedling growing cup with the matrix, wherein a matrix of the seedling bed is composed of peat, mushroom residue, ramulus mori powder and vermiculite according to a weight ratio of 10:3-5:2-3:3-5; using the carbendazim lotion of 0.2% in concentration to soak and disinfect the cuttings, and placing the cuttings in a indolebutyric acid lotion of 1500 mg / L in concentration for soaking to obtain treated cuttings; inserting the treated cuttings into the matrix in the seedling growing cup by 2-3 cm in depth, and using water to drench the matrix after inserting; performing inserting management and acclimatization and transplanting after inserting to obtain clematis root seedlings. By the method, rooting rate reaches higher than 90% after 30-40 days of inserting culture, and inserting survival rate can reach 90%. The method is simple to operate, low in cost and high in propagation speed and survival rate and has great popularization value, and a lot of clematis root seedlings can be obtained quickly.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a cutting vegetative propagation method of Clematis clematis. Background technique [0002] Clematis chinensi (Clematis chinensi), a medicinal plant belonging to the genus Clematis of Ranunculaceae, is also known as iron-footed clematis, iron-horned clematis, iron-footed fairy, iron-footed clematis, iron rake head, etc. Distributed in southern Yunnan, Guizhou, Sichuan, Shaanxi, Guangxi, Guangdong, Hunan, Hubei, Henan, Fujian, Taiwan, Jiangxi, Zhejiang, Jiangsu and other places. The roots of Clematis clematis contain pulsatilla, pulsatilla lactones, sterols, sugars, saponin lactones, phenols, amino acids, etc., and the leaves contain lactones, phenols, triterpenes, amino acids, organic acids, etc. Clematis has the effects of dispelling rheumatism, dredging meridians, eliminating phlegm, saliva, and stagnation of addiction. It can treat gout, stubborn numbness, cold pain in ...

AI Technical Summary

Problems solved by technology

Cutting propagation can maintain the characteristics of the variety, and the cultivated plants grow faster than sowing seedlings, and can be cultivated into large seedlings in a short time, but the cutting seedlings obtained by cutting propagation have poor root systems and cannot form taproots. The survival rate of seedlings is low, and the life span is longer than that of sowing. Seedlings are short and less resistant to stress

At present, there are few studies on the cutting propagation of Clematis clematis. The existing cutting propagation methods of Clematis clematis have problems such as long seedling cultivation period, unstable rooting rate, less root system of cutting seedlings, and weak disease resistance, which lead to problems after seedlings are planted. The low survival rate and slow growth rate are not conducive to the large-scale production of cutting propagation of Clematis clematis
