Problems solved by technology

Although the whitening agent prepared by this method has a certain effect of sterilization and disinfection, insecticide and insect repellent, and antifreeze and sunburn, it has the problem of poor durability and poor rain resistance, and it often needs to be reapplied every few months, which is a waste of manpower. At the same time, the effect of preventing pests, sunburn and fruit tree stripping needs to be further improved

Abstract

The invention discloses a fruit tree whitewashing agent and a high-position whitewashing method, and belongs to the technical field of agriculture. The fruit tree whitewashing agent is composed of, by mass, 12 parts of polyving akohol, 0.09 part of carboxymethylcellulose, 0.035-0.045 part of hydrochloric acid, 19 parts of silica solution, 0.028-0.032 part of urea, 0.025-0.3 part of sodium benzoate, 16 parts of sodium hydroxide, 3 parts of silicon dioxide, 3 parts of magnesium oxide, 100 parts of quick lime, 25 parts of sulfur powder and 10 parts of salt. The whitewashing agent is high in durability and resistant to rainwater scouring, the effect of preventing plant diseases and insect pests is good, secondary smearing is avoided, labor and time are saved, and the phenomena of sunburn and fruit tree sprout are effectively prevented by the adoption of the high-position whitewashing method.

Description

technical field [0001] The invention relates to a fruit tree whitening agent and a high-level whitening method, belonging to the field of agricultural technology. Background technique [0002] Fruit trees need to carry out bar whitening in winter, promptly coat one deck whitening agent at the certain height position of tree bar. The main function of the whitening agent is to sterilize and disinfect, kill and prevent insects, and prevent freezing damage from sunburn. Most of the existing whitening agents are prepared by lime water, sulfur, salt, and animal oil in a certain proportion. The preparation method is as follows: add water to ripen quicklime, add oil and stir, add water to make lime milk, then pour lime sulfur mixture stock solution and salt water, stir well and serve. Although the whitening agent prepared by this method has a certain effect of sterilization, insecticide and insect repellent, and antifreeze and sunburn, it has the problem of poor durability and poo...
