Green prevention and control method for pests in tea garden

Abstract

The invention provides a green prevention and control method for pests in a tea garden. The green prevention and control method is specifically applicable to control of diseases and pests of tea treesand weeds in the tea garden under overcast and rainy conditions. According to the green prevention and control method, green and pollution-free plastic is used as a raw material, and made into a circular arc silver gray and white reflecting cover and an oval arc silver gray and white reflecting cover with sunlight reflecting effects, wherein the circular arc silver gray and white reflecting coverhas a diameter of 15-30 cm, a height of 5 cm and an edge of 2 cm, and the oval arc silver gray and white reflecting cover has an x diameter of 16 cm, a y diameter of 8 cm, a height of 5 cm and an edge of 2 cm. According to the invention, through light reflection of reflecting covers, the illumination between tea rows is increased; by combination of the characteristic that insects and fungi are sensitive to illumination, the effects of repelling tea garden pests like aphids, thrips and empoasca flavescens and inhibiting diseases like tea cake disease are achieved; meanwhile, the reflecting covers can be repeatedly used, are convenient to move and can be randomly made according to terrain sizes.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for green prevention and control of pests in tea gardens. Background technique [0002] Weeds in tea gardens are composed of multiple species and have the characteristics of complex structure, strong stability and rapid growth. It has been proven that if weeds in tea gardens are not controlled, they will not only compete with tea trees for nutrients, but directly affect the normal growth of tea trees; moreover, they may also carry diseases and insect pests or become transitional hosts of tea tree disease pests, indirectly affecting the healthy growth of tea trees, resulting in reduced tea yields. with a decrease in quality. Since tea trees are perennial leaf plants, effective control of weeds in tea gardens has become a regular task in tea garden management. The safest way to control weeds in tea gardens is manual "plowing and weeding" or "mechanical weeding". Ho...

Problems solved by technology

The safest way to control weeds in tea gardens is manual "plowing and weeding" or "mechanical weeding". However, with the rise of labor costs, the input costs are relatively large and the control effect on fast-growing weeds is limited.

Although "chemical weeding" is easy to use and saves a lot of labor, chemical herbicides have a certain impact on plants (including tea trees), pathogens, soil microorganisms and the environment, not only easy to cause environmental pollution, but also harmful to human health Causes harm and does not meet the requirements of green development

At the same time, weeds grow rapidly in the rainy season. Even if "chemical weeding" is used for control, its effect is limited; and "plowing and weeding" is easy to cause soil erosion
