Embodiment

[0039] 200 12-year-old hickory trees were selected as the experimental objects, and they were divided into 4 groups with 50 trees in each group.

[0040] The first group of experimental trees were treated with soil application according to the method provided in this application; the first application time and the second application time are as follows, and each treatment test object is 50 trees.

[0041] Example first application time Second application time 1 February of that year next March 2 June of that year next March 3 April of that year next March

[0042] The second group carries out traditional pruning and top removal, branch pulling and bud carving comprehensive processing to each tree manually by existing methods.

Abstract

The present application discloses a method for promoting hidden buds to germinate new shoots at the bare legs of the large branches of the hickory tree. 2) During the second application time, apply urea to the root of the pecan tree. This method can effectively promote the germination of hidden buds on the bare legs of the large branches of the thin-shelled hickory, increase the number of grafted branches, and at the same time inhibit the vertical growth characteristics of new branches, prevent new branches from forming bare legs again, and can fundamentally solve the problem of light. The formation of the legs and the low germination rate of cryptobuds.

Description

technical field [0001] The application relates to a method for promoting hidden buds to germinate new shoots at the bare legs of large branches of hickory nuts, and belongs to the field of planting and production of hickory nuts. Background technique [0002] Carya illinoensis K.Koch, also known as long hickory and American hickory, is native to the United States and Mexico. It belongs to the tall deciduous tree species of Juglandaceae Hickory. It is a world famous oil-bearing dried fruit tree species. [0003] Thin-shell hickory grows vigorously, and the annual growth of new shoots reaches 1.5-2.5 meters. The growth advantage of the top is obvious, the top buds grow faster, and the branching rate of side buds is low. Trees that have grown for more than 5 years are more likely to have internal bore branches. The bare legs of the side branches lead to the outward and upward movement of the tree fruit, rapid canopy closure of the forest, and low yield per mu. [0004] In the...
