Tea tree grafting method

Abstract

The invention discloses a tea tree grafting method. The tea tree grafting method comprises the following steps that step one, tree stock sawing is performed, upper-portion branches, 10-15 cm away from the ground, of tea trees are sawed off by using an electric hand saw, 1-3 skeleton branches are reserved for each tea tree to serve as the tree stocks; step two, cions are selected, reddish brown semi-lignified mature branches on seed trees are selected, and one internode and one axillary bud are reserved for each cion; step three, tree stock cutting is performed, one corner of the cross section of each tree stock is cut by using a rubber bud grafting knife, and cutting is obliquely performed at the angle of 35 degrees with the cross section to form a cut; step four, cion cutting is performed, two sides of the lower end of each cion-grafted branch are respectively cut to form a wedge shape with one thin side and another thick side, the length of cutting surfaces is smaller than the depth of cuts, and leaves at the upper ends of the cions are sheared off; step five, cion insertion is performed, cions are inserted along one side of the cuts on the same day of cion collection, the thin surfaces of the cions are inward, the thick surfaces of the cions are outward, and cion forming layers is flush with tree stock forming layers during cion insertion; step six, the cions and the connecting cuts are wrapped, the cion forming layers and the tree stock forming layers are aligned, and the tree stock cuts and the parts of the cions except bud eyes are tightly wrapped with plastic bands with the 3 cm width.

Description

technical field [0001] The invention relates to a grafting method, in particular 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 oil tea tree), and 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 tr...

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
