Tea tree grafting method

Abstract

The invention discloses a tea tree grafting method. The method comprises the following steps of 1, sawing rootstocks; 2, selecting scions; 3, cutting the rootstocks; 4, cutting the scions; 5, inserting the scions; 6, binding the scions and joints; 7, conducting management after grafting. An electric hand saw is used for sawing the rootstocks, cuts of the sawn rootstocks are smooth, and phloem is free of tearing. Compared with the traditional mode that a sabre saw is used for sawing the rootstocks, the labor intensity and the labor cost are reduced, and the working efficiency is improved; in addition, an oblique cutting method is adopted, the cuts are small, the water loss area is reduced, and nutrients and energy consumption required by wound healing are reduced; the joints can be sealed by using plastic belts for binding, and a moisture retention effect is achieved on the scions, so that sap produced by the rootstocks and the scions smoothly flows, and the survival rate is improved. By using the oblique cutting method for grafting, the method is simple and easy to implement, and a plastic bag for bagging and a sunshade net for shading are not required after grafting. According to the method, the labor intensity and the grafting cost are greatly reduced, popularization is easy, and the method can be popularized in the improvement of a low-yield tea garden.

Description

technical field [0001] The invention relates to a tea tree grafting method. Background technique [0002] Tea tree belongs to Theaceae, Camellia shrubs or small trees, and the twigs are glabrous. Leaves leathery, oblong or elliptic. The leaves of the tea tree can be used to make tea (different from the tea tree), the seeds can be used to extract oil, the material of the tea tree is fine and dense, and its wood can be used for carving. The distribution is mainly concentrated between 16 degrees south latitude and 30 degrees north latitude. Tea trees like warm and humid climates. The buds start to germinate when the average temperature is above 10°C, and the optimum temperature for growth is 20-25°C; the annual precipitation should be above 1000 mm; Sun-loving and shade-tolerant, it is suitable for growing under diffuse light; its life is divided into seedling stage, juvenile stage, adult stage and senility stage. The age of the tree can reach one or two hundred years, but t...

Problems solved by technology

[0003] Tea tree grafting technology is mostly applied to the method of changing tea trees. By retaining and utilizing the developed root system of the original tea tree, the grafted tea tree will grow vigorously. The current more effective grafting method is: split plastic bag to keep moisture, sun and shade. Method, this method has a high survival rate of grafting, but the cost of grafting is relatively high. According to the test of the relevant science and technology research institute, the method of double bagging and moisturizing is adopted, and the cost of grafting per mu is not less than 992 yuan. The grafting cost per acre of the shade method is not less than 1578 yuan. The cost mainly includes the cost of building greenhouse materials, bagging costs, sunshade nets and labor costs. If the conventional grafting method is used, the grafting cost per mu will be as high as 2100 yuan
