Method for grafting high wild walnut tree with high survival rate

A survival rate, wild iron technology, applied in the fields of botanical equipment and methods, horticulture, application, etc., can solve the problem of inconvenient unbinding, wiping the anvil, tying the strut and topping, and the saw cutting of the rootstock is difficult to heal and tightly wrapped, and cannot be effectively dwarf the tree canopy and other problems, to facilitate the grafting operation and later management, improve the survival rate of grafting, and promote economic development.

Problems solved by technology

For the transformation of wild iron walnuts, the method of "high grafting and head replacement" or grafting on the annual branches after sawing has been adopted, and generally only the stems with a diameter of 7-8 cm or less, and the stems with a diameter of 10 cm There is no corresponding technical report on the transformation of the above big trees
Moreover, there are many drawbacks in the existing technical methods
The method of high-joint-replacement grafting can not effectively dwarf the crown of the tree, and secondly, due to the high joint, it must be operated on the tree during grafting, and it is not convenient for untying, wiping the anvil, tying the pole and topping in the later stage.
The sawing and grafting method requires sawing in the first year and grafting in the second year, which delays the transformation time by one year. At the same time, it is difficult to heal the sawn edge of the rootstock, which will affect the balanced growth of the tree.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with embodiment, but the present invention is not limited in any way.

[0021] The inventor carried out implementation and comparative tests in places such as Panxi Abaimishanqing, Panxi Fagaolaokong, Panxi Dayanzi Cooperative, Tonghongdian Laoxiongqing and other places in Huaning County, Yunnan Province. "Leaving water branches and coating hygroscopic agent" and other technical processes can significantly improve the survival rate of iron walnut grafting. This technical method can be adapted to the grafting of large trees in the range of 8-23cm. The method is simple and the technical process is stable and reliable. Tables 1, 2, and 3 respectively summarize the comparative test results of each embodiment.

Abstract

A method for grafting wild walnut tree with high survival rate includes taking scion in January, sealing it with wax for keeping moisture, sawing the wild walnut tree with 10-23 cm of diameter at the position with 70-150 cm distance from ground, selecting a side branch as water absorbing one, grafting the scion on the residual tree as stock, convering with saw dust, and wrapping with plastic film. Its advantages include high survival rate, and high yield.

Description

1. Technical field [0001] The invention belongs to the technical field of high-yield grafting of fruit trees, and in particular relates to a method for grafting wild iron walnut trees with high survival rate by directly transforming wild iron walnut trees into high-quality, high-yield soaked walnuts. 2. Background technology [0002] Wild iron walnut is a wild resource with a wide distribution and a large number. It is a good thing to benefit the people in mountainous areas by grafting it into high-quality and high-yield soaked walnuts to improve its commercial value and promote the development of the local economy. It is a good thing for double harvest and social benefits. For the transformation of wild iron walnuts, the method of "high grafting and head replacement" or grafting on the annual branches after sawing has been adopted, and generally only the stems with a diameter of 7-8 cm or less, and the stems with a diameter of 10 cm The transformation of above big tree the...
