Technical Field

The application relates to the technical field of cash crop planting methods, in particular to a method for quickly promoting healing of a large kerf formed in shaping and pruning of walnut trees.

Background

Walnut (Juglans regia) Belonging to the phylum angiospermae, class Dicotyledoneae, family Juglandaceae Juglandaceae（）Juglans of Juglans Juglans（L.）It is a tall deciduous tree, also known as walnut and walnut, which can be eaten directly or after frying, or used for extracting oil, preparing cake and candy, not only has good taste, but also has high nutritive value, and is known as "all ages of the world", "longevity fruit", and also known as "four famous dry fruits" together with almond, cashew nut and hazelnut.

The walnut is light-loving and drought-enduring, but afraid of waterlogging, afraid of salt and alkali, strong in disease and pest resistance, and can adapt to various climatic environment conditions and soil types. The walnut kernel contains rich nutrient components, each hundred grams of the walnut kernel contains 15 to 20 grams of protein, 60 to 70 grams of fat, 10 grams of carbohydrate and nutrient substances such as calcium, phosphorus, iron, carotene, riboflavin (vitamin B2), vitamin B6, vitamin E, juglone, phospholipid, tannin and the like which are necessary for a human body. The nutritional ingredients in the walnut have good health care effect on cranial nerves and have the effect of preventing and treating arteriosclerosis. The microelements in the walnut kernel are indispensable for human body, and have the functions of promoting glucose utilization and cholesterol metabolism, protecting cardiovascular system and resisting aging.

As walnuts belong to big crown type arbor species, the following problems are easy to occur in the general production shaping and pruning process: firstly, the larger saw cut formed in the plastic pruning can not be completely healed in time; secondly, the saw cut is easy to be infected by germs to cause rot; thirdly, the saw cut is exposed to the outside xylem, and the whole tree is weakened because the stem (main branch) is rotten in the medullary after being dehydrated and dried and infected by germs.

Disclosure of Invention

In view of the above-mentioned drawbacks in the prior art, the present application aims to provide a method for promoting healing of a large kerf of a walnut tree, which has the advantages of high healing speed, good healing degree, no easy scar formation, no easy rot, and no easy decay of xylem and medulla on the main trunk, main (big) branch, etc.

The purpose of the application is realized as follows: a method for promoting healing of large saw cuts of walnut trees quickly comprises the following steps:

step one, sawing off large branch pile: for the big branches to be thinned, firstly, pile retaining and sawing are carried out;

step two, trisection deep cutting bark (phloem): taking the middle point of the lower edge of the saw cut section of the remaining pile as a base point, longitudinally trisecting the bark (phloem) of the whole remaining pile, and longitudinally and deeply cutting the bark to the xylem from the saw cut section to the base of the remaining pile along a trisection line by using a sharp edge;

step three, stripping the bark (phloem) from the xylem: turning over the trisection bark (phloem) deeply cut to the xylem to completely expose the xylem of the remaining pile, and sawing and removing the top half bark (phloem) at the middle position of the trisection together with the exposed peg of the xylem from the base part;

step four, covering the saw kerf: turning the two remaining equal parts of bark (phloem) from bottom to top, and completely covering the saw cut in a crossed manner;

step five, the bark (phloem) is attached to the saw cut: fully contacting the inner cambium of the upturned bark (phloem) with the section of the saw cut, repeatedly winding and firmly binding the upturned bark (phloem) and the main branches by using a rope for compaction, cutting off the redundant part of the upturned bark (phloem) exceeding the edge of the saw cut, and sealing and moisturizing the edge of the saw cut by using sealing glue;

step six, shading and packaging: the saw cut is covered by black plastic cloth, and the outside is firmly tied by a rope.

Firstly, determining the position of a saw cut of a remained pile before sawing, wherein the length of the remained pile is at least more than 0.5cm of the diameter of the saw cut formed after thoroughly removing big branches from a base; before sawing, the bark (phloem) is cut off by a saw under the determined position of the cut of the pile, and then the saw is cut off from the upper part of the cut to prevent the bark (phloem) of the pile from being torn before the large branch is cut off.

In the third step, two equal parts of bark (phloem) left cannot be sawn when the peg stake peg of the xylem is sawn off, and meanwhile, the exposure time of the inner part of the bark (phloem) and a saw mouth in the air is reduced.

In the fourth step, before the crossing covering, the bark (phloem) epidermis located at the lower layer after the crossing is scraped by a knife until the green inner cortex layer is exposed, and then the upper layer bark (phloem) is tightly pressed on the inner cortex layer of the lower layer bark (phloem).

Compared with the prior art, the application has the following remarkable advantages: 1. compared with the traditional saw cut which is sealed by paint or sealing glue, the saw cut is not easy to be infected by germs, the wound healing speed is higher, the healing degree is better, scars are not easy to form on the main trunk, the main (big) branch and other parts, and rot is not easy to generate; 2. compared with the traditional simple treatment method, the method has the advantages that the healing speed of the saw cut is improved by more than 70 percent, and the rotten disease is reduced by more than 80 percent; 3. compared with the traditional method, the method can effectively solve the problems of late healing of the large saw cut, rot caused by saw cut bacterial infection, dehydration of xylem exposed at the saw cut and pulp decay of the main trunk (main branch) caused by pathogenic bacteria infection, thereby further causing the tree vigor to be weak, and lays a foundation for the healthy growth, yield and quality improvement of the later-period tree body.
