Trunk whitewashing composition, trunk whitewashing agent containing trunk whitewashing composition, and application

Abstract

The invention discloses a trunk whitewashing composition, a trunk whitewashing agent containing the trunk whitewashing composition, and application. The composition is composed of hydroxypropyl methyl cellulose and an ethylene-vinyl acetate copolymer, wherein the weight percentage of vinyl acetate in the ethylene-vinyl acetate copolymer is 70 to 95%. In the trunk whitewashing agent, the mass percentage of the composition is 1 to 70%, and the rest components of the trunk whitewashing agent are accessory materials. All the components of the trunk whitewashing composition show substantial synergistic interaction; and the trunk whitewashing composition can effectively alleviate occurrence of phenomena like overwintering freeze injury, sunburning and sprouting and improves the growth conditions of plants. The composition or the trunk whitewashing agent containing composition has the advantages of environment friendliness of each component, stable quality, a small usage amount, a wide application scope and convenience and safety in application.

Description

technical field [0001] The invention relates to the field of tree whitening agents, in particular to a tree trunk whitening composition, a tree trunk whitening agent containing the composition and applications. Background technique [0002] In urban landscaping, evergreen tree species can add color and vitality to the monotonous autumn and winter seasons. However, unlike the southern region, few evergreen tree species can survive after being transplanted to the north. The main reasons are as follows: : The first is the occurrence of freezing damage. Extreme low temperature, extreme daily cooling and extreme continuous cooling events are prone to occur in northern China. If the extreme low temperature weather lasts too long, many evergreen tree species will be frostbitten and freeze to death; second. It is the damage caused by sunburn to the trunk. Due to the strong daytime sunlight in the northern winter, the temperature of the trunk facing the sun rises, the cells thaw, the...

Problems solved by technology

However, the traditional whitening agent mainly has the following four major problems after use: 1. The quality of the traditional whitening agent is unstable. The raw material is mineral components, the fineness is poor, and it is easy to settle. Poor thickness uniformity; 2. Poor viscosity, poor film-forming property, prone to cracking and peeling, short protection time, often needs to be painted more than 2 times; 3. Single active ingredient, poor heat preservation and moisturizing effect, can only be simply applied Whitening effect, limited anti-freezing and anti-sunburn effects; 4. Traditional whitening agents are highly alkaline, and if used year after year, it is easy to cause or aggravate root soil salinization, especially in northern areas where use is limited; 5. Traditional whitening agents The anti-insect and anti-bacterial effect is poor, and most of the active ingredients of pesticides are easy to decompose and fail in an alkaline environment, so it is impossible to add pesticide ingredients when applying
