Whitewashing agent for preventing trunk of plant from being frozen in winter and sunned in summer

Abstract

The invention provides a whitewashing agent for preventing a trunk of a plant from being frozen in winter and sunned in summer. The whitewashing agent is prepared from the following components in parts by weight: 700 parts of calcium oxide, 5 to 291 parts of heavy calcium carbonate, 1 to 50 parts of inorganic sterilizing agent, 2 to 15 parts of film forming agent, 5 to 200 parts of redispersible latex powder, 1 to 30 parts of dispersant and water, wherein the content, in part by weight, of the water is 2 times the total content, in part by weight, of the components. The whitewashing agent provided by the invention can be adhered to the trunk for 4 to 6 months after being smeared on the trunk, can be used for realizing insect-prevention and freezing-prevention effects in the winter, and can be used for realizing a sunning-prevention effect in the summer; the whitewashing agent prepared by selecting and using refined quick lime can be brushed and can be also atomized; the efficiency is greatly improved; common table salt is not adopted in raw materials; the salinization on soil is avoided and the pollution to an environment is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a whitening agent for preventing freezing of plant trunks in winter and sun protection in summer. Background technique [0002] In agricultural production, commercial crops such as fruit trees, pears, peaches, and walnuts have their trunks painted white in late autumn and early winter, late spring and early summer; white measures. Its purpose is to prevent freezing in winter and sun protection in summer, and at the same time prevent insects and diseases, and also have the effect of beautifying the environment in gardens. [0003] The whitening agent currently used in production is mainly composed of quicklime, lime-sulfur mixture, salt, animal oil, and water. The main function of quicklime is to whiten tree trunks, and the lime-sulfur mixture is used for insect and disease prevention. Adhesion on the trunk, animal oil plays the role of moisturizing film.

AI Technical Summary

Problems solved by technology

[0004] Existing whitening agents have the following defects in use: (1), the time attached to the trunk is short, generally about two months; (2), in order to increase the time attached, the amount of salt must be increased, and the salt is absorbed by rainwater. After leaching, it flows into the land, which accelerates the salinization of the soil and destroys the environment; (3), the quicklime used has poor fineness, low purity, and many residues, so mechanical spraying cannot be used, and only manual brushing is required, which consumes manpower and material resources large, inefficient
