Problems solved by technology

[0003] Aiming at the technical problem that the survival rate of cuttages is still not high although hormone substances are used to treat the cuttings of hard-to-root forest trees, the present invention provides a method for treating the mother plants of ear-picking that improves the survival rate of forest tree cuttings, effectively It solves the problem of low survival rate of cuttings of difficult-to-root tree species. It is a major breakthrough in cutting seedling breeding technology and is of great significance to the breeding of improved forest species. It can be used in production to rapidly breed improved forest species on a large scale, driving the rapid development of the seedling industry, and producing Significant economic, social and ecological benefits

Embodiment 1

[0025] A kind of processing method of ear-picking mother plant that improves the survival rate of forest tree cuttings, taking catalpa as an example, realizes through the following steps:

[0026] 1) Selection of ear-picking mother plant: select a Catalpa tree plant grafted with a catalpa root that is healthy and free of diseases and insect pests under 5 years of age as the mother plant for twig cuttings and ear-picking;

[0027] 2) Prepare nutrient carbon source and endogenous auxin compound solution: the nutrient carbon source and endogenous growth-promoting substance solution is composed of 0.05% borax, 0.2% sucrose and 50ppm indole acetic acid compound aqueous solution;

[0028] 3) Treatment time for ear-picking mother plants: From mid-May when the leaves have fully expanded and sprouted new shoots in spring to mid-August during the tree growth period, choose a sunny day with a breeze, and at 10:00 in the morning when the transpiration of the trees is strong conduct;

Abstract

The invention discloses a scion mother tree treatment method for increasing the wood cutting shoot survival rate. The method is achieved through the following steps of 1 selection of a scion mother tree; 2 preparation of compound liquid of a nutrient carbon source and endogenous auxin; 3 treatment of the scion mother tree; 4 trunk injection of the scion mother tree; 5 girdling treatment of scion mother tree branches; 6 branch cutting. According to the method, by adopting the methods of injecting the nutrient carbon source and endogenous growth promoting substances to a trunk of the scion mother tree, conducting branch girdling treatment and the like, the survival rate of tender wood branch cutting is greatly increased, the technical bottleneck that the survival rate of tender wood branch cutting is low is successfully solved, and the tender branch cutting survival rate of woods difficult to root is made to reach up to 97.5%; the method is simple and convenient and easy to operate, and improved forest tree varieties can be massively and quickly bred when the method is applied to production.

Description

technical field [0001] The invention belongs to the field of forest tree seed breeding, in particular to a method for treating ear-picking mother plants for improving the survival rate of forest tree cuttings. Background technique [0002] The vegetative propagation of forest trees can make the reproduced plants maintain all the excellent genetic traits of the female parent. Therefore, vegetative propagation method is widely used in the breeding production of improved tree species. At present, the commonly used methods for asexual propagation of forest trees mainly include cuttings, grafting and tissue culture. Grafting seedlings are prone to phenomena such as "small feet", recession and shallow root system. The procedures of group seedling cultivation are cumbersome, high cost and difficult to be used in production. However, cutting seedlings are the most convenient, not only low cost, but also fast propagation speed and simple method 1. It is easy to operate, and it is c...
