Evaluation method for occurrence degree of insect damage to tea trees in tea regions of southern Anhui, and prevention method of insect damage to tea trees in tea regions of southern Anhui

Abstract

The invention discloses an evaluation method for occurrence degree of insect damage to tea trees in tea regions of southern Anhui, and a prevention method of the insect damage to the tea trees in thetea regions of the southern Anhui. According to the evaluation method, occurrence quantities of empoasca flavescens, tea geometrid and aleurocanthus spiniferus are taken as the basis, and the overalloccurrence level of the insect damage to tea gardens is judged by comparing the ranges of the occurrence quantities; on the basis of the evaluation method, three green prevention technical modes are developed correspondingly in the prevention method, so that the situations that conventional prevention methods are simple and cannot be quantized and prevention modes cannot be selected scientificallyand reasonably according to different insect damage occurrence degrees are changed. The evaluation method has the advantages that the occurrence degree of the insect damage to the tea trees in the tea regions of the southern Anhui is divided into three levels, namely level I, level II and level III, so that judgment of the insect damage occurrence degree can be quantized, and foundation is laid for research on the prevention modes; the prevention method has the advantages that the corresponding prevention modes can be selected specifically according to the different insect damage levels, so that simplification of conventional methods and techniques and high pesticide residue volume are changed fundamentally, and quality and safety of tea leaves are guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical field of pest control in tea gardens, and in particular relates to a method for judging the occurrence degree of main pests and diseases of tea trees in southern Anhui tea areas and a control method thereof. Background technique [0002] Tea trees are perennial woody leaf crops. At present, in order to protect tea garden plants from insect damage and enable tea trees to grow quickly and healthily, pesticides are often used to prevent and control tea garden insect pests. However, pesticides are often toxic and easily pollute the surrounding environment such as the air. Moreover, controlling pests by spraying pesticides can not only cause the death of pests, but also kill beneficial animals, which is not conducive to environmental protection and ecological balance. Moreover, the pesticides sprayed on the tea trees are volatile, so that the pesticides only have medicinal effects in a certain period of time, and canno...

Problems solved by technology

[0004] Prior to this, there have been sporadic reports in the industry of using physical control, agronomic control, and biological control measures to control pests. However, how to select the ones with good control effects and low environmental pollution according to the overall occurrence and characteristics of tea garden pests in southern Anhui? Green control methods have not been reported
