Plate budding method for quecus mongolica

Abstract

The invention provides a plate budding method for quecus mongolica, and relates to the technical field of asexual breeding of quercus mongolica. The method comprises the specific steps that scion-picking mother trees which grow robustly and are free of diseases and pests are selected, scions are picked instantly for use, a blade for grafting and a polyvinyl chloride thin film for strip binding areprepared, and quinquennial quecus mongolica saplings are selected as rootstocks; double-person grafting is adopted in order to shorten the exposure time of grafted buds in air, wherein one person cuts the rootstocks, and the other person obtains the grafted buds; a cutting lower cut of each rootstock is internally cut by 45 degrees, each grafted bud is externally cut by 45 degrees, it is ensuredthat the grafted buds are inserted into the rootstocks, and connectors are engaged; meanwhile, a straight line which is 2 cm long is cut below the cutting part of each rootstock and reaches a cut of the corresponding phloem in depth to serve as a drainage line. By means of the method, the survival rate of asexual breeding of the quercus mongolica is greatly increased, the use of the scions is reduced, and more excellent clones can be provided; compared with tissue culture breeding, the breeding cost is greatly reduced, the breeding process of improved varieties of the quercus mongolica is accelerated, and the method is a new quecus mongolica breeding technology which is easy to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of asexual propagation of Quercus mongolica, in particular to a method for budding of Quercus mongolica. Background technique [0002] Quercus mongolica (Quecus mongolica) is a national second-class precious tree species and the main secondary forest tree species in the forest regions of Northeast China. It grows in mountains with an altitude of 200m to 2100m. It often grows below 600m in Northeast China and above 800m in North China. It often forms small pure forests or mixed forests with birches on sunny and semi-sunny slopes. Russia, North Korea, and Japan are also distributed. Quercus mongolica is an excellent tree species for building windbreak forests, water conservation forests and fire prevention forests. It is very suitable for solitary planting, cluster planting or mixed with other trees to form forests. Its leaves can be used to feed tussah silkworms; wood can be used for vehicles, ships, constr...

AI Technical Summary

Problems solved by technology

In the actual process of forestry production, seed breeding is mostly used, but because the seed propagation of Quercus mongolica is easy to cause variation, its excellent traits cannot be fixed, and the rapid propagation technology of Quercus mongolica test tube seedlings is not easy to promote in actual production. very low
