A kind of seabuckthorn bud cutting rapid propagation seedling raising method

Abstract

The invention belongs to the technical field of seedling cultivation of forest trees and provides a method for cutting, rapid propagation and seedling cultivation of tender buds of seabuckthorn in order to overcome the defects that during current cutting of hard branches and tender branches, cuttings are difficult to obtain and the cost for manually obtaining the cuttings is high. A micro-cuttagetechnology with the tender buds of the seabuckthorn as the cuttings can be directly used in a cutting and rapid propagation system of the tender buds of the seabuckthorn for production. Thousands of buds serving as the cuttings are taken from a perennial parental seabuckthorn plant with excellent properties at the same time, and roots can grow in 7-15 days. By adopting a treatment method of usingIBA, potassium permanganate and aspirin, the survival rate of the roots is increased by 20% in comparison with a method of only using hormones for treatment of the tender buds. A used substrate preferably contains vermiculite and river sand with the proportion of 1:1, nutrient soil is not added, and 0.1% potassium permanganate is used for soaking and disinfection first, so that mildewing before the tender buds are rooted is effectively controlled. Through establishment of the seabuckthorn asexual seedling cultivation system, propagation of the excellent seabuckthorn parental plant can be greatly expanded in a short time, and high practicability is achieved. In addition, the operation is simple, the cost is low, and the method can be used for production and is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of forest tree seedling cultivation, and in particular relates to a method for quickly propagating seedlings by cuttings of seabuckthorn tender shoots. Background technique [0002] sea ​​buckthorn ( Hippophae rhamnoides Linn. ) There are two methods of reproduction: sexual reproduction and asexual reproduction. However, in the actual production process, the seedlings are usually propagated by vegetative propagation-cutting seedlings. Cutting seedlings can quickly obtain a large number of clone seedlings with the same genetic traits as the mother plant, which has the advantages of high rooting rate and easy survival. At present, there are two main methods of raising seedlings of seabuckthorn cuttings widely used in production: hard branch cuttings and soft branch cuttings. But these two methods have two obvious disadvantages: first, the cuttings and cuttings are limited. In order to ensure the survival r...

Problems solved by technology

But these two methods have two obvious disadvantages: first, cutting cuttings are limited

Twig cuttings often choose 15-20cm lignified or semi-lignified twigs as cuttings. It takes more than 3 years for the selected high-quality asexual seedlings to be pruned and cut; secondly, the labor cost for cuttings is high

Seabuckthorn has many thorns and small branches, so it is labor-intensive to cut them into clean cuttings of suitable length, which is not conducive to the large-scale rapid propagation of superior species

Therefore, the traditional method, cost and speed of hardwood and tenderwood cuttings have restricted the propagation of seabuckthorn elite species and the development of seabuckthorn industry.
