Problems solved by technology

[0003] At present, Populus euphratica is mainly propagated by cutting seedlings, but the survival rate of conventional cuttings is low and there is a problem that it is easy to die after cutting. In the prior art, rooting powder such as GRR or ABT is used to soak the cuttings before cutting, but there is still no guarantee. Sufficient adventitious roots grow, and it is easy to cause waste of cuttings and increase the cost

Embodiment 1

[0025] A kind of rapid cutting propagation method of Populus euphratica, comprising the following steps:

[0026] Step 1: Cutting collection

[0027] (1) Cutting: Select 1-2 year old branches or sprouted branches of robust adult trees. In order to improve the survival rate of cuttings, the ear material should be selected from unlignified new shoots or root sprouts with strong regeneration ability and many buds. The middle and lower part of the seed bar is suitable, the xylem is fully mature and cannot exceed 2 / 3 of the seed bar. Cut with a sharp bar cutter or pruning shears, the cut length is 18-20cm, the diameter is 0.8-2.0cm, and 2 full buds are left on the top. The upper end of the cuttings is cut flat and the lower end is cut obliquely to avoid splitting and damage to the phloem of the cuttings. The cuttings are bundled (every 50 pieces are 1 bundle), and sprinkled with water to moisturize.

[0028] (2) Storage: Cuttings that cannot be cut in time should be stored. Afte...

Embodiment 2

[0041] A kind of rapid cutting propagation method of Populus euphratica, comprising the following steps:

[0042] Step 1: Cutting collection

[0043](1) Cutting: Select 2-year-old branches or sprouted branches of robust adult trees. In order to improve the survival rate of cuttings, un-lignified new shoots or root sprouts with strong regeneration ability and many buds should be selected as ear materials. The middle and lower part of the seed bar is suitable, the xylem is fully mature and cannot exceed 2 / 3 of the seed bar. Cut with a sharp bar cutter or pruning shears, the cut length is 20cm, the diameter is 0.8-2.0cm, and 2 full buds are left on the top. The upper end of the cuttings is cut flat and the lower end is cut obliquely to avoid splitting and damage to the phloem of the cuttings. The cuttings are bundled (every 50 pieces are 1 bundle), and sprinkled with water to moisturize.

[0044] (2) Storage: Cuttings that cannot be cut in time should be stored. After the cutt...

Abstract

The invention discloses a breeding method of a Xiaoxi populus euphratica variety, which adopts Xiaoxi populus euphratica hybrid populus as a variety for cutting breeding, and comprises the following steps: collecting cuttings, treating the collected cuttings, cutting in a greenhouse and carrying out tending management. When the cuttings are treated, the lower ends of the cuttings are immersed in an IBA solution, a good rooting effect is achieved, meanwhile, the upper ends of the cuttings are smeared with a wound healing agent, it is guaranteed that the cuttings are not infected by germs in the growth and reproduction process, and the survival rate of cuttage of the populus euphratica var. Diversifolia is increased to a certain degree. The Populus euphratica bred by the method is short in seedling time, developed in root system, excellent in quality and stable in shape, and can thrive after being transplanted to saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to a method for rapid propagation of cuttings of populus euphratica small x species. Background technique [0002] Small × Populus euphratica is a male clone with Populus euphratica as the female parent and Populus euphratica as the male parent through artificial distant hybridization and breeding. When the tree species are mixed, the resistance is generally poor, and the diseases and insect pests are serious, it is particularly rare and precious as a native hybrid. After many times of cross-breeding experiments, Xiao x Hu retains the excellent genetic traits of the parents, grows rapidly, is more resistant to salt and alkali than the female parent Populus euphratica, and is easier to reproduce than the male parent Populus euphratica. This patented variety was taken from Dengkou County in 2008. The research results of Shalin Farm and Inner Mongolia Agricultural Un...
