High-survival-rate cutting breeding method for quercus variabilis oak

Abstract

The invention relates to the technical field of cork oak cutting, in particular to a cork oak high-survival-rate cutting breeding method which comprises the following steps: S1, selecting cutting time and cutting slips; s2, carrying out base part carving treatment; S3, disinfecting the selected cutting slips; s4, preparing a cutting medium; S5, dipping roots with a rooting agent; s6, cutting the cuttings obtained in the previous step; s7, temperature and humidity control after cuttage; S8, management in the cuttage period; S9, management before transplanting; according to the cuttage method, the cuttage survival rate of the quercus variabilis oak can be increased to 80% or above; the adventitious roots can easily penetrate through the outside in a base carving treatment mode, rooting is more facilitated, meanwhile, induction of the adventitious roots can be adjusted through the rooting raw powder matched with the mixed material, and the rooting effect is better.

Description

technical field [0001] The invention relates to the technical field of cork oak cutting technology, in particular to a method for cutting and breeding of cork oak with high survival rate. Background technique [0002] Cork oak is an important multi-purpose industrial tree in my country. Its roots, leaves, husks, seeds, bark, trunk and other organs and tissues can provide raw materials for food, medical, chemical, furniture, construction, cosmetics, national defense and other industrial production . Known as precious native trees, colorful leaf landscape trees, carbon-fixing and dust-retaining trees, strategic timber trees, ecological restoration trees, water conservation trees, water and soil conservation trees, fire and windproof trees, soil improvement trees, drought-resistant and stress-resistant trees, and industrial raw materials tree, woody food source tree, tussah raw material tree, fungus matrix tree, major technology tree, etc. It is an indispensable natural resour...

Problems solved by technology

[0004] Compared with seed propagation, vegetative propagation can ensure the stable inheritance of traits. Cutting propagation is the most widely used technical measure in vegetative propagation. However, the biological characteristics of Quercus variabilis are extremely difficult to root, resulting in a very low survival rate of cuttings. It has become known in the industry that it is not possible to measure the cutting propagation of Quercus variabilis with conventional cutting ideas of other types of trees. At the same time, this characteristic also seriously limits the propagation and promotion of excellent species of Quercus cork.
