Rapid cutting propagation method of eucommia ulmoides

Abstract

The invention discloses a rapid cutting propagation method of eucommia ulmoides. The method comprises the following steps that cutting shoots for cutting are collected; a cutting seedbed is prepared, wherein a matrix of the seedbed is prepared from peat, mushroom residues, mulberry twig powder and vermiculite according to the weight ratio of 10:(2-3):(3-4):(2-4), and the matrix is disinfected by spraying carbendazim liquid with the concentration of 0.3% and then contained in a seedling raising cup; the cutting shoots are soaked and disinfected by the carbendazim liquid with the concentration of 0.3% and then put into indolebutyric acid liquid with the concentration of 2,000 mg / L to be soaked, and treated cutting shoots are obtained; the treated cutting shoots are cut into the seedling raising cup, the depth that the cutting shoots are cut into the matrix is 3 cm to 4 cm, and the matrix is thoroughly drenched with water after cutting; cutting managing and seedling hardening and transplanting are conducted after cutting, and then eucommia ulmoides seedlings can be obtained. According to the method, after cutting culture is conducted for 15 days to 20 days, the rooting rate reaches 90% or above, and the cutting survival rate can reach 85%. The method has the advantages of being easy to operate, low in cost, high in propagation speed and survival rate and the like, a large quantity of eucommia ulmoides seedlings can be quickly obtained, and a very good popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a rapid multiplication method for cuttings of Eucommia ulmoides. Background technique [0002] Eucommia ulmoides Oliver, also known as Bakelite, is a plant of Eucommia ulmoides. Eucommia is a unique species in China, distributed in Shaanxi, Gansu, Henan, Hubei, Sichuan, Yunnan, Guizhou, Hunan, Anhui, Shaanxi, Jiangxi, Guangxi and Zhejiang provinces, and is now widely planted in various places. Contains eucommia gum, glycosides, alkaloids, pectin, fats, resins, organic acids, ketose, vitamins, vitamin E, vitamin B and β-carotene, etc. The fatty acid composition of the fatty oil contained in the seeds is linolenic acid, linoleic acid, oleic acid, stearic acid, and palmitic acid. Eucommia has the effects of invigorating the liver and kidneys, curing waist and spine pain, flaccidity of feet and knees, urination, dampness and itching in the genitals, high blood pressure, and a...

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 Eucommia ulmoides, and the existing cutting propagation methods of Eucommia have problems such as long seedling cycle, unstable rooting rate, few root systems of cutting seedlings, and weak disease resistance, which lead to low survival rate and low disease resistance after planting. The growth rate is slow, which is not conducive to the large-scale production of Eucommia cutting propagation
