Problems solved by technology

[0004] At present, the polymer film-forming agents contained in commercially available wound varnishes are mostly polyacrylamide, acrylate, water-based polyurethane, modified epoxy resin, etc., and these film-forming agents have certain effects on the cambium cells of willow Toxicity, causing direct contact with the smear and the death of adjacent cambium cells, delaying the formation of callus in the cambium of willow bark, making the wounds of willow cadres unable to heal quickly, and affecting the healthy growth of trees
[0005] In addition, the smears in the prior art only rely on chemical agents to heal the wound, without considering the nutrients needed for wound healing from the perspective of plant tissue growth, so that the wound healing speed is relatively slow

Abstract

The invention relates to a smearing agent for promoting poplar-willow-trunk wound healing. In every 1,000 parts by weight of the smearing agent, the smearing agent is prepared from, by weight, 0.002-5parts of a plant growth regulator, 11-125 parts of a high-molecular film forming agent, 0.1-10 parts of a tackifier, 1-50 parts of an inert carrier, 0.1-30 parts of an antimicrobial substance, 0.1-1part of a coloring indicator and the balance water; the high-molecular film forming agent is prepared from, by weight, 1-20 parts of polyvinyl alcohol, 5-50 parts of sodium carboxymethylcellulose, 5-50 parts of chitosan and 0-5 parts of polyethylene glycol. The smearing agent is nontoxic and harmless to poplar-willow cambial cells, and the wound healing speed of poplar-willow trunks can be increased. The invention also discloses a preparing method for the smearing agent for promoting poplar-willow-trunk wound healing, and the smearing agent prepared with the method is applied to poplar-willow-trunk wound healing treatment, and has the advantages of being wide in bactericidal spectrum, low in toxicity, free of residue, safe, reliable, capable of protect wounds and the like.

Description

technical field [0001] The invention relates to the technical field of tree wound treatment medicaments, in particular to a varnish for promoting wound healing of willow trunks, a preparation method and application thereof. Background technique [0002] Poplars and willows are widely used as urban trees because of their rich varieties, wide ecological adaptability, strong stress resistance and vitality, fast growth, easy reproduction, tall trees, beautiful tree shapes, large shading areas, and good effects. The number of backbone tree species for greening, farmland shelterbelt construction, surrounding greening, road and river bank greening is as high as 5 billion, and most of them are female plants. The catkin pollution produced by female willow plants has been the focus and hot issue of social concern for many years, and the treatment of catkin catkins has become an important measure to build an ecological civilization and improve people's livelihood and well-being.
