Abstract

The invention discloses a physical killing device of empoasca vitis in a tea garden. The physical killing device comprises a random sound source; an interface circuit, a sound frequency control circuit, a sampling conversion circuit, a PWM modulation circuit, an amplifying circuit, a filter circuit and a directional acoustic emission array are sequentially connected to the random sound source; a protection circuit is connected to the amplifying circuit in parallel; a power supply is also connected to the sound frequency control circuit. The physical killing of the empoasca vitis in the tea garden is realized, so that the harm to a tea tree is reduced. The invention further discloses a physical killing method of the empoasca vitis in the tea garden.

Description

technical field [0001] The invention belongs to the technical field of plant protection and pest control devices, relates to a device for physically killing green leafhoppers with false eyes in tea gardens, and also relates to a method for physically killing using the device. Background technique [0002] Leafhopper Leafhopper belongs to Homoptera and is the main pest in my country's tea gardens. It has a wide distribution and a large number of occurrences. Due to the small size of the cicada, hidden hazards, and rapid reproduction, the Yangtze River Basin can produce 9-11 generations per year, Guangdong and Guangxi can produce 12-13 generations, and Hainan can produce 15 generations. There are many generations and serious overlapping of generations, so it is difficult to control. large, seriously affecting the yield and quality of tea. [0003] False-eyed green leafhoppers have tenderness, and like to inhabit on the back of buds and young leaves. The 2-3 leaves under the b...
