Whitewashing agent applied to protection of tree trunks

Abstract

The invention discloses a whitewashing agent applied to the protection of tree trunks and application. The whitewashing agent comprises the following components in percentage by weight: 40 to 45 percent of calcined lime, 2 to 3 percent of lime sulfur mixture stock solution, 3 to 6 percent of lime sulfur mixture residues, 2 percent of salt, 0.5 percent of grease and the balance of water, wherein the lime sulfur mixture residues are a mixture which mainly contains silicon oxide. A preparation method for the whitewashing agent comprises the following steps of: adding the water and lime hydrate into a reaction kettle, and heating and stirring continuously for later use; putting the calcined lime into a hot-water boiler, and dissolving to prepare lime milk solution, putting sulfur powder which is blended to form paste in advance, stirring and mixing while adding the pasty sulfur powder for 40 to 60 minutes until liquid medicine has a rufous color, and the liquid surface has a layer of membrane, cooling the liquid medicine and collecting supernatant; and mixing the two liquid mixtures, heating, stirring and cooling to obtain the whitewashing agent. By applying the whitewashing agent, fruit tree barks can be prevented from being cracked, the resinosis can be avoided, the day-night temperature difference of branches can be reduced, and pathological changes caused by cold damage and insect attack can be prevented effectively, so the whitewashing agent can be used in various fields.

Description

field of invention [0001] The invention relates to the technical field of protective paint for fruit tree poles, in particular to the technical field of a whitening agent for fruit tree poles and its application in protecting tree poles. Background technique [0002] Fruit trees are perennial plants. In winter and early spring, due to the large temperature difference between day and night, the trees are prone to "sunburn" and frostbite. Existing fruit growers usually use quicklime diluted with tap water to brush the trunk of the fruit tree with a brush to prevent insects and reduce tree stem diseases, but because quicklime is diluted with tap water, it often burns people's skin or the phenomenon that the concentration of dilution is not suitable takes place and damages the tree stem. Occurs, badly needs standardization and finalization as the fruit tree whitening agent that is easy to use and convenient and practical insect-proof effect. [0003] Lime sulfur mixture is an i...

Problems solved by technology

However, the existing liquid lime sulfur mixture has the following disadvantages: 1. the liquid lime sulfur mixture cannot be stored for a long time and needs to be boiled for immediate use, which is very inconvenient; 2. residual waste water and waste residue pollute the environment: 8. the iron pot after boiling Rusted and scrapped, increasing product cost

[0006] At the same time, the production process of domestic manufacturers of crystalline stone sulfur mixtures adopts the crystallization mother liquor recycling method. This method will emit a large amount of hydrogen sulfide gas into the atmosphere and generate a large amount of filter residue. The production cycle is long, the cost is high, and the environment is harmful. Pollution is high, and waste brings pressure on the environment
