Twig grafting method for engrafting in crown of camellia oleifera tree

Abstract

The invention relates to a twig grafting method for engrafting in a crown of a camellia oleifera tree. According to the method, 4 to 7 lateral branches, which are 50 to 80cm away from a base part, are 1 to 2 years old and have trunk diameters not less than 0.6cm, on a main branch of an old camellia oleifera tree are selected as graft stocks, and the grafting time is spring. <0}{0><}0{>The grafting method is based on single bud cut grafting or cleft grafting and comprises the following steps of: 1) performing stock treatment; 2) cutting scions; 3) inserting the scions; 4) tying and binding. Or the method is based on shield bud grafting with wood and comprises the following steps of: 1) cutting out stocks; 2) peeling buds; 3) inlaying the buds; and 4) binding. <}0{>According to the method, grafting wounds are small, and the possibility of bacterium infection is low; by use of opening angles of the lateral branches, crowns can be shaped and molded easily; the current annual increment is high and can be up to 60 to 150cm; the survival rate is as high as 92%; as a whole, the method is labor-saving, material-saving and low in cost; bagging and shading are not needed, fussy binding is omitted, and the method is simple to operate and easy to popularize.

Description

technical field [0001] The invention relates to a method for grafting plants, in particular to a method for grafting high-grafting and crown-changing twigs of camellia oleifera. Background technique [0002] Camellia spp. is the most productive oil species in the Theaceae family Camellia spp. Camellia oleifera in a broad sense refers to the tree species with high oil content in the seeds of Camellia plants and a certain cultivation area. Camellia oleifera is originally produced and mainly planted in my country. Together with olive, oil palm and coconut, it is known as the four largest woody oil plants in the world. The current area of ​​camellia oleifera forests in China is about 4 million hm2, accounting for more than 80% of the cultivated area of ​​woody edible oil species in my country. . The main product of camellia oleifera is camellia oil, which is a healthy edible oil promoted by the Food and Agriculture Organization of the United Nations. Its unsaturated fatty acid c...

Problems solved by technology

[0004] Camellia oleifera is grafted directly on the large branches of camellia oleifera (rootstock) by grafting, cutting, tearing and inlaying on the large branches of camellia oleifera (rootstock). The characteristic of this method is that the rootstock of the grafting part Relatively thick, the common problems after grafting are: first, the survival rate of grafting is low; It is not easy to make up after grafting for the first time, and it is difficult to survive after grafting

[0008] Judging from the state of the art, most of the patents mainly solve the problems of reproductive survival rate and suitable grafting method. In traditional methods, 2 to 4 twig buds are inserted into a large grafting interface at the same time, and after survival, they form clusters and grow together. , it is not convenient for crown forming and modeling, and it is extremely unsightly
