Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] The device material selection density is 1.4g / cm 3 Pure polyvinyl chloride, after adding plasticizer, the color of polyvinyl chloride film is white, and the density range is controlled at 1.15-2.00g / cm 3 , Toughness standard: Wrap around a mandrel with a diameter of 2cm without cracks or breaks. This material will be made into a flat film for the protection device. White is used to reflect strong light, the density standard is used to prevent rodents from chewing on the trunk, and the toughness prevents snapping.

[0031] The main component of water-absorbent resin is potassium polyacrylate, standard: mesh number (accounting for more than 80%) is 30-60; water absorption multiple (deionized water, 60min) g / g≥430; water absorption multiple (1:100) s: ≤70 ; Saline absorption speed (2:50) s: ≤55; water retention (0.9%N): ≥33; water absorption under pressure (norm...

Abstract

The invention discloses a multifunctional trunk protection device. The multifunctional trunk protection device comprises a polyvinyl chloride flat plate film. The polyvinyl chloride flat plate film is provided with round hollows, hollow cones and strip sockets. Strip guide bands are distributed between the strip sockets. The multifunctional trunk protection device is mainly used in fields of (1) Chinese scholar trees, elms, crape myrtles, albizzia, alamos, goldenrain trees, willows, sakuras and greening and timber trees in Rosaceae and Lauraceae, wherein pests and disease damage usually occur in the greening and timber trees, and parts of the greening and timber trees are damaged by coccid, long-horned beetles and aphid; (2) tree species like blueberry trees and michelia susceptible to freezing damage; and (3) Magnolia, alamos, camphor trees and sassafrases susceptible to sunburn. According to multifunctional trunk protection device, the following functions of (1) sterilizing, avoiding bacterial infection and speeding up mechanical damaged wound healing, (2) insecticide, insect prevention and preventing rodents from gnawing barks, and (3) avoiding trunk freezing damage and sunburn can be achieved.

Description

technical field [0001] The invention relates to the field of tree protection, in particular to a multifunctional trunk protection device. Background technique [0002] Existing technical methods for protecting tree trunks are mainly to use whitening liquid to artificially whiten the 1.2m (or 1.5m) trunk section above the trunk base in early spring and late autumn and early winter each year. This technical method has the following deficiencies: (1) The whitening solution is lost due to rainwater erosion; (2) The uniformity and thickness of the manual coating paint is uneven, which aggravates the damage to the local tree trunk; (3) The paint will fall off naturally after air drying; ( 4) Repainting is required twice a year; (5) The scope of application is narrow, and it is mostly used in urban greening areas; (6) It cannot inhibit the growth of shoots and functional roots at the base of the trunk. Contents of the invention [0003] In order to solve the above-mentioned t...
