Problems solved by technology

[0004] Since walnut belongs to the large-crown arborization tree species, the following problems are prone to occur in the usual pruning process: first, the large saw cuts formed in the plastic pruning cannot be completely healed; Rot disease; the third is that the xylem exposed to the saw cuts loses water and cracks, and after being infected by pathogens, it causes the main trunk (main branch) pith to rot inwards and cause the whole tree to weaken

Embodiment 1

[0018] Embodiment 1: a kind of walnut tree large kerf fast healing method comprises the following steps:

[0019] Step 1. Saw off large branches with piles: For the large branches to be removed, firstly cut them with piles;

[0020] Step 2. Deeply cut the bark (phloem) into three equal parts: take the middle point of the lower edge of the saw cut section of the pile as the base point, divide the bark (phloem) of the entire pile into three equal parts longitudinally, and use a sharp blade to saw from the bottom along the third dividing line. Cut longitudinally from the section of the mouth to the base of the pile to the xylem; when cutting deep, use force, and the movement should be crisp and neat, in one go, so that the cut surface formed is smooth and smooth;

[0021] Step 3. Stripping the bark (phloem) from the xylem: Turn up the third part of the bark (phloem) that has been cut deep into the xylem to completely expose the xylem of the pile, and remove the upper part of the ...

Embodiment 2

[0028] Example 2: In the spring of 2017, in the Woody Grain and Oil Forest Farm of Wensu County, Xinjiang Academy of Forestry Walnut Breeding Experimental Garden (East Longitude: 37°03', North Latitude: 79°49'), this item was used in pruning Rapid healing method for large saw kerf. The park is located on the northwestern edge of the Tarim Basin in southern Xinjiang. It has a warm temperate and arid desert climate with abundant heat and a maximum temperature of 38.4°C. The soil is sandy loam with deep soil layer and good air permeability. It is an old continuous planting area with medium organic matter content and is suitable for walnut planting.

[0029] Select two improved walnut varieties (Wen 185 and Xinxin 2) for rapid healing of large sawn kerf. The specific steps are as follows:

[0030] Step 1. Don’t be in a hurry before spring plastic pruning starts. First, conduct a preliminary survey on the overall situation of the whole garden. As far as individual plants are conce...

Abstract

The invention discloses a quick healing method for a walnut tree large saw opening. The method includes six steps of cutting off large branch retaining piles, deeply cutting phloem into three equal parts, peeling phloem from xylem, covering the saw opening, adhering phloem to the saw opening, and shading and wrapping. Compared with the traditional saw opening which is simply sealed with a paint orsealing glue, the saw opening is not easy to be infected by bacteria, the wound healing speed is faster, the healing degree is better, scars are not easy to form on parts such as trunk and main branches, and rot disease is not easy to generate. Compared with the traditional method, the method can effectively solve the problems of slow healing of the large saw opening, rot caused by bacterial infection of the saw opening, dehydration of xylem exposed by the saw opening and tree growth declining caused by decay of the trunk pith due to bacterial infection, and lay a foundation for the healthy growth, yield and quality improvement of the tree body in the later period.

Description

technical field [0001] The application relates to the technical field of economic crop planting methods, in particular to a method for rapidly healing large saw cuts formed in pruning of walnut trees. Background technique [0002] Walnut( Juglans regia ) belongs to Angiosperm, Dicotyledonae, Juglandaceae （ Juglandaceae ） , walnut （ Juglans L.） , is a tall deciduous tree, also known as walnut and Qiang peach.
