Method for grafting, shaping and pruning of Panlong chestnut

Abstract

The invention provides a method for grafting, shaping and pruning of Panlong chestnut. According to the invention, double tongue grafting is adopted for grafting of a young tree; a bamboo pole must beerected to assist growth; single-trunk top grafting is adopted for grafting of a big tree; during shaping, buds located at the upper part of the arched back of a tree are emphasized to be used as extension branches of a main branch; and during pruning, the number of fruiting mother branches of the Panlong chestnut is small, i.e., the number of reserved mother branches is determined by tree potential, wherein each fruiting branch group is reserved with 3 to 4 mother branches when the tree potential is strong, two mother branches when the tree potential is moderate, and one mother branch when the tree potential is weak, and the phenomenon of a large number of empty shells is generated if the number of reserved fruiting mother branches of the Panlong chestnut is overlarge. By adoption of themethod provided by the invention, the survival rate of grafting is high, and large-area planting can be realized; meanwhile, by adoption of the method provided by the invention for shaping and pruning, the beautiful drooping shape of a tree is maintained, and the effect of high-yield fruiting is guaranteed.

Description

Technical field [0001] The invention relates to a method for grafting, shaping and pruning a Panlong chestnut, belonging to the technical field of forest and fruit tree cultivation. Background technique [0002] Panlong chestnut is a unique resource among chestnut tree species. It is a variety for both production and greening. Because its branches are naturally drooping, the tree shape is extremely graceful, and the shape is "Dragon Claw Sophora". It can be used as a street tree or park decoration. In addition, the nuts of Panlong Li are black and oily, delicious and sweet, and have high growth and cultivation value. Therefore, the characteristics of Panlong chestnut, which can be viewed and produced, determine the uniqueness of its plastic pruning, that is, it is necessary to maintain a beautiful drooping tree shape, but also to ensure the effect of high yield, and ultimately achieve "two birds with one stone" "Effect. However, the grafting methods in the prior art are not sci...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems in the prior art that the survival rate of grafting is low and it is not conducive to large-scale planting, the present invention provides a method of grafting, shaping and pruning of Panlong chestnut. This method has a high grafting survival rate and can be planted in a large area. Using this method for pruning can not only maintain a beautiful and drooping tree shape, but also ensure the effect of high yield and fruit.
