A broad-leaved tree injection component and its operating method

Abstract

The invention belongs to the technical field of pest control equipment, and discloses a broad-leaved tree injection assembly, which includes a punching part and a plug. The punching needle of the punching part is provided with a first through hole; the plug includes a T-shaped The connected end and the long rod part, the upper ring of the long rod part is provided with an elastic annular barb, the outer diameter of the long rod part is not larger than the aperture diameter of the first through hole, and the outer diameter of the annular barb The diameter is greater than the aperture of the first through hole, and the outer diameter of the end is greater than the outer diameter of the annular barb; the plug is provided with a second through hole, and the two ends of the second through hole are Sealed with a pierceable membrane. The invention also discloses an operation method of the broad-leaved tree injection unit. Using the operation method of the invention to carry out the injection operation can minimize the wound of the tree, and the plug is placed in the punched hole to make it difficult for mold, bacteria and insects to enter Broad-leaved trees, using the broad-leaved tree injection assembly of the present invention can better perform aseptic injection on broad-leaved trees.

Description

technical field [0001] The invention belongs to the technical field of pest control equipment, and in particular relates to a broad-leaved tree injection assembly and an operation method thereof. Background technique [0002] At present, the degree of forest insect pests continues to increase, and forest insect control has become a hot spot in current research. Most of the existing technologies use simple instillation methods for trees and hanging needle drip methods to instill pesticides to prevent insect pests. Spraying pesticides to prevent insect pests is harmful to the environment. It is highly polluted and affected by wind and rain, so it is not recommended to use it. [0003] Simple instillation method for trees: use a puncher to punch a hole with a diameter of about 5 mm in the trunk and a depth of about 10 mm into the wood, insert the injection needle into the hole obliquely from top to bottom to the xylem, and connect the pesticide bottle to the xylem. On the inje...

Problems solved by technology

[0005] Both of the above two infusion methods need to punch larger holes through a puncher, and external microorganisms and dust can easily enter the tree and cause infection

Based on the above defects, the invention patent with the notification number CN109906801A discloses an injection needle and its injection method, which can perform pesticide injection operations on trees without using a puncher to punch holes, but the injection needle in this application The injection operation is mainly aimed at coniferous trees. The bark of coniferous trees is thick and tough, and the active sapwood part is wider. The injection needle can be used to inject the agent into each part of the active sapwood of coniferous trees, while the bark of broad-leaved trees is thin and its vegetative system is tight. Relying on the cambium, the range is very narrow, and the efficiency of injecting broad-leaved trees with the above-mentioned injection needle and its injection method is not high

[0006] In order to solve the technical problem of "inefficiency", we propose a broad-leaved tree injection assembly and its operation method
