Problems solved by technology

[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

Embodiment 1

[0015] In the embodiment of the present invention, a method for raising seedlings by cuttings to improve the drought resistance of tea saplings, the specific method is as follows:

[0016] (1) Choose a strong tea tree mother tree, cut the lignified and strong axillary buds on the tea tree mother tree as cuttings, trim the cuttings to a length of 4.4cm, keep one leaf, cut the upper port flat, and the distance from the petiole is 8mm , the lower port is cut obliquely, the height of the cut is 13 mm, and the angle of the cut is 50 degrees. Immerse the lower port of the cuttings in the treatment agent and soak for 50 minutes. Take out the leachate until there is no water dripping, and put it in a refrigerator for refrigeration. 44min, the tea tree cuttings have to be cut;

[0017] The treatment agent is made of the following raw materials in parts by weight: 1.6 parts of magnesium phosphate, 0.12 parts of stevia polysaccharide, 0.17 part of Achyranthes bidentata polysaccharide, 0....

Embodiment 2

[0023] In the embodiment of the present invention, a method for raising seedlings by cuttings to improve the drought resistance of tea saplings, the specific method is as follows:

[0024] (1) Select a strong tea tree mother tree, cut the lignified and strong axillary buds on the tea tree mother tree as cuttings, trim the cuttings to a length of 4.5cm, keep one leaf, cut the upper port flat, and the distance from the petiole is 8.5 mm, the lower port is obliquely cut, the height of the oblique cut is 14mm, and the angle of the oblique cut is 55 degrees. Immerse the lower port of the cuttings in the treatment agent for 55 minutes, take out the draining agent, drain until there is no water dripping, and put it in the refrigerator for refrigeration After 47 minutes of treatment, the tea tree cuttings have to be cut;

[0025] The treatment agent is made of the following raw materials in parts by weight: 1.7 parts of magnesium phosphate, 0.13 parts of stevia polysaccharide, 0.18 pa...

Embodiment 3

[0031] In the embodiment of the present invention, a method for raising seedlings by cuttings to improve the drought resistance of tea saplings, the specific method is as follows:

[0032] (1) Choose a strong tea tree mother tree, cut the lignified and strong axillary buds on the tea tree mother tree as cuttings, trim the cuttings to a length of 4.6cm, keep one leaf, cut the upper port flat, and the distance from the petiole is 9mm , cut the lower port obliquely, the height of the oblique shear is 15mm, and the angle of the oblique shear is 60 degrees. Immerse the lower port of the cuttings in the treatment agent and soak for 60 minutes. Take out the leachate until there is no water dripping, and put it in the refrigerator for refrigeration. 50min, wait for the tea tree cuttings to be cut;

[0033] The treatment agent is made of the following raw materials in parts by weight: 1.8 parts of magnesium phosphate, 0.14 parts of stevia polysaccharide, 0.19 part of Achyranthes bident...

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.
