Method for preventing and controlling aleurocanthus spiniferus

Abstract

The invention discloses a method for preventing and controlling aleurocanthus spiniferus. The method comprises the steps of establishing an ecological tea garden, pruning branches and cleaning the teagarden, combining preventing and controlling of pests such as coccids, aphids, red spiders and the like before germination in early spring, performing drainage well, increasing application of organicfertilizers, digging out aleurocanthus spiniferus parasitic plants at the periphery of the tea garden, preventing and controlling larvas, conducting physical preventing and controlling, conducting reasonable picking, conducting medical preventing and controlling and closing the garden in winter. According to the method for preventing and controlling the aleurocanthus spiniferus, by improving ecological conditions of the tea garden, ecological diversity of the tea garden is increased, by pruning the branches and cleaning the tea garden, the tea garden maintains good ventilation and light transmission, by cultivating robust tree vigor, pest and disease resistance of trees are improved, and by conducting biological preventing and controlling, physical preventing and controlling and pesticidepreventing and controlling, the number of the leurocanthus spiniferus and damage caused by the leurocanthus spiniferus are reduced, so that preventing and controlling are achieved, and yields and profits are increased.

Description

technical field [0001] The invention relates to the field of tea, in particular to a method for preventing and treating the tea black thorn whitefly. Background technique [0002] Black thorn whitefly, also known as orange thorn whitefly, black thorn whitefly nymphs settle on the back of tea leaves and suck the juice, and excrete a large amount of "honeydew" on the lower leaf surface, causing the parasitism of bituminous bacteria and inducing the prevalence of soot disease. In severe cases, the tea tree is pitch-black, hindering photosynthesis; resulting in weak tree vigor, no tea to pick, and even dead branches and dead trees; adults hardly cause harm to tea, but they will attack people in groups or bite people when picking tea. cause great inconvenience. Contents of the invention [0003] The object of the present invention is to provide a kind of method of preventing and treating whitefly, by improving the ecological conditions of the tea garden, increasing the ecologi...
