specific Embodiment approach 1

[0035] Specific Embodiment 1: This embodiment provides a new type of environmentally friendly whitening agent for tree trunks. The whitening agent includes the following raw materials: alginate, calcium sulfate, diatomaceous earth, β-cyclodextrin, white wood fiber, instant Silicate, retarder, xanthan gum, bifenthrin aqueous solution.

specific Embodiment approach 2

[0036] Specific embodiment 2: This embodiment is to further limit the whitening agent described in specific embodiment 1. The parts by weight of raw materials in the whitening agent described in this embodiment are as follows: 10-20 parts by weight of alginate, 12-18 parts by weight of calcium sulfate, 50-70 parts by weight of diatomaceous earth, 2-10 parts by weight of beta-cyclodextrin, 5-20 parts by weight of white wood fiber, 2-10 parts by weight of instant silicate, 1 - 6 parts by weight retarder, 2-7 parts by weight xanthan gum, and a solid-to-liquid ratio of 1:1.8-1:2.2200-1000 times the bifenthrin aqueous solution. Other compositions and connection methods are the same as those in Embodiment 1.

[0037] In this embodiment, by adding β-cyclodextrin as the slow-release carrier of bifenthrin, it plays the role of slow release of the drug effect and improves the effective period of tree maintenance and disease prevention and insect control in winter. The added thermal insu...

specific Embodiment approach 3

[0038]Specific embodiment three: this embodiment further limits the calcium sulfate described in specific embodiment two, and the calcium sulfate described in this embodiment is calcium sulfate dihydrate or calcium sulfate hemihydrate. Other compositions and connection methods are the same as those in Embodiment 1.

[0039] In this embodiment, calcium sulfate dihydrate is preferably calcium sulfate dihydrate as the calcium-based source of the whitening agent. Since the water content in calcium sulfate dihydrate is relatively high, it is easier to react with alginate to form gel-like calcium alginate .

Abstract

The invention relates to a novel environment-friendly tree trunk whitewashing agent and a preparation method thereof, belongs to the technical field of tree maintenance, and provides the novel environment-friendly tree trunk whitewashing agent in order to solve the problems that a traditional whitewashing agent is poor in whitewashing effect, trunk-boring pests are difficult to control, the trunk-boring pests are prone to falling off, the heat preservation effect is poor, and the trunk-boring pests have toxicity and are harmful to the environment. The whitening agent comprises the following raw materials: alginate, calcium sulfate, diatomite, beta-cyclodextrine, white wood fiber, instant silicate, a retarder, xanthan gum and a bifenthrin aqueous solution, and the whitening agent is neutral, is friendly to the ecological environment, does not cause soil hardening and salinization, has a gel property, can fill bark cracks of tree trunks, and has a good whitening effect. The tree trunk protection agent has the advantages that the tree trunk protection agent can well contact with overwintering eggs in tree bark cracks, the killing effect is improved, the tree trunk protection agent has certain thickness and hardness after being coated on tree trunks, damage of trunk borers to the tree trunks can be reduced, and the product is mainly used for protecting the trees.

Description

technical field [0001] The invention belongs to the technical field of tree maintenance, and in particular relates to a novel environment-friendly whitening agent for tree trunks and a preparation method thereof. Background technique [0002] In the process of tree maintenance, the winter protection of trees is very important. In winter, the overwintering places of viruses and pests that harm trees are relatively concentrated and fixed, which is a critical period for extermination. The quality of extermination effect is related to the base of pests and diseases in the next spring and the workload of pest control. At the same time, the temperature is low in the morning and evening in winter, and the sun radiates heat at noon, which is likely to cause sunburn and bark cracking caused by high temperature differences. [0003] Therefore, during the wintering protection of trees, measures such as straw ropes or straw curtains are often used to protect the trunk, and the trunk is...
