Method for promoting germination of new shoots from latent buds at bare leg parts of carya illinoensis large branches

A technology for thin-shell hickory and hickory trees, which is applied in the fields of fertilization methods, gardening methods, botanical equipment and methods, etc., can solve the problems of strong upright growth of new shoots, low germination rate of new shoots, and large engineering workload. Inhibit the re-formation of bare legs, promote the germination of cryptobuds, and reduce the effect of manpower input

Embodiment

[0039] 200 12-year-old pecan trees with thin shells were selected as experimental subjects, 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 shown in the table below, and each treatment subject is 50 trees.

[0041] Example First application time Second application time 1 February of the year March of the following year 2 June of the year March of the following year 3 April of the year March of the following year

[0042] In the second group, the traditional methods of pruning and removing the tops, pulling branches and carving buds of each tree were carried out manually.

Abstract

The invention discloses a method for promoting the germination of new shoots from latent buds at the bare leg parts of carya illinoensis large branches. The method comprises the following steps: (1) applying paclobutrazol to the root soil of a carya illinoensis tree within the first application time; and (2) applying urea to the root soil of the carya illinoensis tree within the second applicationtime. The method can effectively promote the germination of new shoots from latent buds at the bare leg parts of carya illinoensis large branches, the number of grafted fruit branches is increased, meanwhile, the vertical growth characteristic of the new shoots also can be inhibited, the new shoots are prevented from forming bare leg parts again, and the problems of the formation of the bare legparts and low germination rate of the latent buds can be fundamentally solved.

Description

Technical field [0001] The application relates to a method for promoting the germination of new branches of the hidden buds at the bare legs of the thin-shelled pecan large branches, and belongs to the field of the thin-shelled pecan planting production. Background technique [0002] Thin-shelled pecan (Carya illinoensis K.Koch), also known as long pecan and American pecan, is native to the United States and Mexico. It belongs to the tall deciduous tree species of the genus Hickory of the Juglans family. It is a world famous oil-bearing dried fruit tree species. [0003] The thin-shell pecan grows vigorously, the annual growth of new shoots reaches 1.5 to 2.5 meters, the top growth advantage is obvious, the top bud grows faster, the lateral bud formation rate is low, and the trees grown for more than 5 years are more likely to have no inner stem The bare legs of the side branches cause the tree to move outward and upward, the forest canopy closes quickly, and the yield per mu is l...
