Chinese chestnut tree pruning method

Abstract

The present invention relates to fruit shaping method, and is especially Chinese chestnut tree pruning method. The method includes young tree pruning, ten years old tree pruning and old tree pruning. The young tree pruning includes the steps of: pinching and stem fixing to select and remain three main branches; cutting back central branch and three main branches; selecting and remaining side branches and cutting opposite branches; determining remaining direction of side branches; and determining the angles of branches. The ten years old tree pruning includes the following steps: selecting and remaining dominant branches; thrice sawing to widen angle; suppressing old branch growth and promoting new branch growth; and remaining middle branches. The old tree pruning includes the following steps: eliminating too dense branches, updating branches, and remaining proper amount of new branches. The method can increase the yield greatly.

Description

Technical field: [0001] The invention relates to a method for shaping fruit trees, in particular to a method for pruning young chestnut trees. Background technique: [0002] At present, in the chestnut producing areas, there are ultra-low yields from young trees to old tree orchards. The reasons for the low yield of young trees are as follows: [0003] ①Ultra-density planting, most fruit farmers believe that the more trees planted per unit area, the higher the yield, and the result is serious canopy closure without fruiting; [0004] ②Too many branches are left, not pruned according to the rules of the tree, and the stems are not fixed, so that the branches grow in clusters at the same height level, resulting in dense branches, poor lighting, and many seams, but there are many blind seams, and the result is still not good. Yield; [0005] ③The fertilizer and water are infinitely increased, because the density is too high and there are too many branches left, which origina...

Problems solved by technology

[0004] ②Too many branches are left, not pruned according to the rules of the tree, and the stems are not fixed, so that the branches grow in clusters at the same height level, resulting in dense branches, poor lighting, and many seams, but there are many blind seams, and the result is still not good. Yield;

[0005] ③The fertilizer and water are infinitely increased, because the density is too high and there are too many branches left, which originally caused canopy closure. If the fertilizer and water are increased, the tree will have no horizontal space and can only accelerate upward growth. Due to the lack of light, the flower buds cannot be differentiated, so it cannot result;

[0006] ④ Pruning has no rules. If the fruit grows, the branch will be kept, and the fruit will not grow, so that the inside of the tree will become more and more light, and the branches will grow into an umbrella column, so that a small amount of fruit will be on the outer tip. The quality is not good
