Tea tree planting disease and insect pest prevention and control method

Abstract

The invention discloses a tea tree planting disease and insect pest prevention and control method. The tea tree planting disease and insect pest prevention and control method comprises the steps that 1, an herbicide is added to quick lime, even mixing is performed, then the quick lime mixture is uniformly scattered to soil in a plowing layer, the quick lime and the soil are uniformly mixed, water is sprayed to wet the soil, rectangular pieces are covered by black films, and tea trees are transplanted after the black films are put for 5-7 days; 2, from the first ten-day period of April to the first ten-day period of June, predatory mites are scattered in a tea garden in which four or more years old of tea trees are planted; 3, in July to September in a morbidity peak period of initially planted one or two years old of tea trees, 1% of Bordeaux mixture and 2% of tea bran water are sprayed for 3-4 times in a mixed mode; 4, starting from the first ten-day period of July, one solar insecticidal lamp is installed every 13320-16650 m<2> in the tea garden till the last ten-day of October; 5, at a disease and insect pest stage, one section of dead epidermis is slightly scraped from staggered positions of two sides of each tea tree trunk to forma semi-circular ring respectively, 40% omethoate missible oil stock solution or liquid of 1000-1500 times of 80% dichlorvos is coated.

Description

technical field [0001] The invention relates to the technical field of tea tree planting, in particular to a method for preventing and controlling tea tree planting diseases and insect pests. Background technique [0002] Pest control measures are divided into agricultural control, physical control, chemical control and biological control measures. At present, chemical control measures are mostly used in conventional production, and pesticides are commonly used methods. Physical control such as yellow board backboard, black light, sweet and sour liquid lure, etc. Agricultural control: mainly crop rotation, scientific use of organic fertilizers, scientific management, suitable cultivation methods, etc. , the application technology of some biological fungi, etc. [0003] At present, the method of treating tea plant diseases and insect pests generally adopts the method of chemical control, and utilizes broad-spectrum chemical agents to kill bacteria and insects. Tests have sh...

AI Technical Summary

Problems solved by technology

Tests have shown that long-term use of chemical agents is prone to phytotoxicity, especially long-term use of a drug can make pests resistant, pollute the environment, and kill natural enemies

At the same time, after the use of pesticides, the amount of pesticide residues is higher
