Air delivery variable spray test platform and simulation test method

Abstract

The invention discloses an air delivery variable spray test platform, which comprises a rack, wherein a driving system, an air delivery system and a spray system are arranged on the rack, and the driving system is in transmission connection with the air delivery system and the spray system; and a control system is arranged near the test platform, and a canopy structure analysis module, an air volume decision module and a spray volume decision module are embedded in the control system. Operating parameters can be automatically adjusted according to the canopy structure of fruit trees, such as canopy volume, leaf area, tree height, tree age, production season and the like, so that the phenomenon that local overapplication and local control effect are not ideal coexist due to extremely unevenliquid medicine deposited on a unit leaf area is avoided, and the quality of fruit trees and the effective utilization rate of pesticides are improved.

Description

technical field [0001] The invention belongs to the technical field of plant protection machinery, and in particular relates to a wind-driven variable spray test platform and a simulation test method. Background technique [0002] Wind-driven spraying is the most commonly used technology for pesticide application in orchards. The pesticide is sprayed on the canopy target according to a fixed dose. At present, the principle of air-driven variable spraying has been recognized by many scholars, but the important links of variable spraying, such as information collection, spraying decision-making and implementation, still need a lot of research. However, the current research methods mainly use field experiments, and the test platform only has a single function, and lacks a test platform for the influence of canopy structure, operation parameters, spray parameters, and (canopy information) collection parameters on variable spray quality. Because the application parameters cannot...

Problems solved by technology

However, the current research methods mainly use field experiments, and the test platform only has a single function, and lacks a test platform for the influence of canopy structure, operation parameters, spray parameters, and (canopy information) collection parameters on variable spray quality. Because the application parameters cannot be automatically adjusted according to the fruit tree canopy structure (such as canopy volume, leaf area, tree height, tree age and production season, etc.), resulting in extremely uneven liquid medicine deposited on the unit leaf area, resulting in local excessive application The phenomenon of unsatisfactory coexistence of drugs and local control effects seriously affects fruit quality
