Control method, system and device for accurately applying pesticide to tobaccos and application

Abstract

The invention belongs to the technical field of tobacco pesticide application control, and discloses a control method, system and device for accurately applying pesticide to tobaccos and application.A speed control wheel is used for accurately applying the pesticide to the tobaccos, and corresponding hardware devices and matched operation parameters are adopted for different development stages ofthe tobaccos; accessories such as a flow control main board, a multi-stage spray head and a horizontal auxiliary wheel are matched for use to reduce a spraying blank area or an invalid area of the prevention and treatment pesticide; an adjustable pressure pump determines the effective application range of the pesticide through the constant pesticide box pressure; the flow control device adjusts the pesticide flow at any time according to the change of the step speed of an operator through the step speed monitoring of the operator; the multi-stage spray head and the horizontal auxiliary wheelmeet the special requirements of pest control in different growth periods of the tobaccos; and the flow control mainboard only needs to input simple data information to complete parameter configuration of the whole system. The requirements of current precise pesticide application technicians, instruments, sites and the like are reduced, and the requirements of different tobacco planting productionareas can be met.

Description

technical field [0001] The invention belongs to the technical field of tobacco application control, and in particular relates to a control method, system, device and application for precise application of tobacco. Background technique [0002] At present, the research and development of precision pesticide application technology for tobacco is much less than that of large-scale agriculture. According to the few relevant research data, the fog machine drifts within 10m, and the mist machine and conventional sprayer have good control effects on tobacco budworm and red spot disease. And the difference is not huge, but the fog machine works the most efficiently and uses the least amount of medicine. The electric sprayer is easy to use, the nozzle design is reasonable, and the drug output is uniform. The utilization rate of new types of pesticides such as self-propelled sprayers suitable for dry land is about 20% higher than that of traditional manual sprayers. In the selection...

AI Technical Summary

Problems solved by technology

In the present stage of tobacco production, there are still problems such as large amount of pesticides, low utilization rate, low efficiency of plant protection machinery, high labor intensity of farmers, and excessive pesticide residues in primary flue-cured tobacco. Studies have shown that the utilization rate of tobacco pesticides is only 20%- 40%
