Preparation method for forest microcapsule anti-biting agent

Abstract

The invention provides a preparation method for a forest microcapsule anti-biting agent. The method comprises the steps that 1, water is added to lime blocks for a reaction to generate hydrated lime which is pasty, and after the hydrated lime is stored for 3 days, sodium silicate and water are added, and composite slurry is prepared; 2, beef tallow, mutton tallow, benzyl benzoate, surfactant and nonivamide are prepared into microcapsules; 3, the composite slurry and the microcapsules are mixed, wherein the microcapsules account for 1-30% by weight; then water is added to regulate the baume degree to 28 degrees, and then the forest microcapsule anti-biting agent is obtained; the composite slurry contains, by weight, 8-10% of calcium hydroxide and 0.5-1.5% of sodium silicate. The prepared microcapsule anti-biting agent contains no toxic pesticide and is environmentally friendly, the prevention effect lasts for more than half a year, the anti-biting effect is much higher than that of a common anti-biting agent and can reach 95% and 98% to the maximum, and trees can be effectively protected for safe overwintering.

Description

technical field [0001] The invention relates to a method for manufacturing a microcapsule anti-gnawing agent for forest trees, belonging to the technical field of plant protection agent manufacturing in the chemical industry. Background technique [0002] The bark of fruit trees, forest belt trees, greening trees, and garden seedlings in northern forest areas, grasslands, and pastoral areas is often vulnerable to being eaten by cattle, sheep, hares, and mice in winter, resulting in tree death and serious damage to greening. Especially after heavy snow covered the ground, mice could not find food and gnawed on the bark under the snow, causing the seedlings to die in pieces. [0003] The traditional forest belt trees are whitewashed with lime water, which has a certain effect on killing pests and insect eggs on the surface of the bark, but it has little effect on preventing cattle, sheep, hares, and mice from eating the bark in heavy snow days, because animals eat the bark.

Problems solved by technology

[0003] The traditional forest belt trees are whitewashed with lime water, which has a certain effect on killing pests and insect eggs on the surface of the bark, but it has little effect on preventing cattle, sheep, hares, and mice from eating the bark in heavy snow days, because animals eat the bark. Huge economic losses are caused to the fruit industry every year

[0004] Lime slurry is a strong alkaline substance, and general pesticides will decompose quickly when added. Adding toxic pesticides is not safe for livestock and has a negative impact on the environment. Therefore, there is currently no good way to prevent animals from destroying trees.
