Systematic and universal method for cutting propagation of large branches of arbors

Abstract

The invention discloses a systematic and universal method for cutting propagation of large branches of arbors. The systematic and universal technical method aims at overcoming internal unfavorable factors for rooting of cuttings of the large branches of the arbors and promoting survival of the large branches during rooting and cuttage. The method includes the stages such as selective breeding of the cuttings, treatment before cuttage and treatment after cuttage and is characterized by comprising the steps that a high-permeability strong cell activator is adopted for improving the activity of meristematic cells; multiple hormones and diphenols are adopted for enhancing effective effects of rooting hormones to promote induced growth of root primordia and growth of roots; growth regulators are adopted in tree crowns for prolonging the sustained contribution time of buds and leaves to the endogenous rooting hormones; rooting inhibitors are eluted, rooting assisting materials are supplemented, and other operation is conducted. Internal restrictions of rooting and cuttage of the large branches are overcome, and the systematic and universal method is provided for the cutting propagation of the large branches of the arbors with production advantages.

Description

technical field [0001] The invention belongs to the field of garden plant propagation, and in particular relates to a systematic and universal method for cutting propagation of large branches of arbors. Background technique [0002] Large-branch cutting refers to the method of directly cutting and rooting large side branches that grow well on trees, and cultivating them into trees that meet engineering or landscape requirements in a short period of time. For some tree species that are easy to root, large-branch cuttings have been used for direct afforestation in production, such as poplar, dry willow, weeping willow, etc. The diameter of the cuttings used for cutting is generally 3-10cm, and the length is generally 150-250cm. When bonsai is produced, the diameter of the cuttings can reach 20-40cm, but the length is shorter. Large branch cutting is a very practical technology in gardening, forestry, and fruit tree production. It has huge production advantages and ecological ...

AI Technical Summary

Problems solved by technology

Compared with the analysis of unfavorable factors for rooting of large-branch cuttings, these patented technologies and research cases have obvious deficiencies in the following aspects: only a single hormone is used for pre-planting treatment; there is a lack of strong measures to improve the vitality of meristematic cells and to relieve rooting inhibition and supplement rooting aids. measures; post-planting management did not try to prolong the life of leaves and buds on branches and maintain their vitality, which are very important for rooting of large branch cuttings

Therefore, the adaptation object of above-mentioned prior art is very narrow, does not have universal significance
