Cutting seedling method for improving drought resistance of tea seedlings

Abstract

The invention belongs to the technical field of tea planting and in particular relates to a cutting seedling method for improving drought resistance of tea seedlings. The method specifically comprisesthe following steps: (1) pruning cuttings, remaining one leaf, straightly shearing from the upper end, obliquely shearing from the lower end, immersing the lower end in a treatment agent to be soaked, taking out the drain agent, draining until any water drop does not drop, and performing cold storage treatment to obtain tea cuttings for cuttage, wherein the treatment agent is prepared from the following raw materials: magnesium phosphate, stevia polysaccharide, achyranthes bidentata polysaccharides, polysaccharides of caulis polygoni multiflori, guanidinoacetic acid and water; (2) performingcutting on the tea cuttings for cuttage in a nursery substrate of a seedling raising greenhouse, wherein the nursery substrate is prepared from the following raw materials: river sand, leaf mold, sheep manure, fresh salix leaves, fresh apple leaves, magnesium stearate, maltol, calcium glycinate and polygala polysaccharides. The chlorophyll content, relative water content and proline content of teaseedling leaves under drought stress conditions are effectively improved, so that the tea seedlings have excellent drought resistance and can normally grow under drought conditions.

Description

technical field [0001] The invention belongs to the technical field of tea tree planting, in particular to a cutting seedling raising method for improving the drought resistance ability of tea tree seedlings. Background technique [0002] Water is one of the important environmental factors that affect plant growth. It is very important to the growth, survival and development of plants. The adaptation of plants to the environment depends on the water supply of the environment. The requirements and adaptation of trees to water conditions are based on their water relationship. Compared with non-endangered plants, endangered plants have poor viability and poor adaptability in terms of physiological ecology. Most endangered plants show physiological characteristics of drought intolerance, and frequent drought stress will inhibit plant growth. growth, and even cause the death of the plant; tea tree is one of the plants that are not tolerant to drought, frequent drought can easily ...

[0002] Water is one of the important environmental factors that affect plant growth. It is very important to the growth, survival and development of plants. The adaptation of plants to the environment depends on the water supply of the environment. The requirements and adaptation of trees to water conditions are based on their water relationship. Compared with non-endangered plants, endangered plants have poor viability and poor adaptability in terms of physiological ecology. Most endangered plants show physiological characteristics of drought intolerance, and frequent drought stress will inhibit plant growth. growth, and even cause the death of the plant; tea tree is one of the plants that are not tolerant to drought, frequent drought can easily lead to the failure of normal growth of the tea tree, and even cause the death of the tea tree, causing serious economic losses to the tea tree growers, so it is urgent to invent a A method to improve the drought resistance of tea trees, and promote the extensive promotion of tea tree planting
