Pesticide droplet retention performance detection system and detection method

Abstract

The invention discloses a pesticide droplet retention performance detection system and detection method, and belongs to the technical field of pesticide performance testing. A detection unit of the detection system comprises a detection box body, a weighing machine, a bending rod and a droplet holding part. The weighing machine is arranged at the bottom of the detection box body, the bottom end ofthe bending rod is fixed to the weighing machine, the droplet holding part is hung downwards at the top end of the bending rod, and the droplet holding part is arranged under a liquid medicine sprayer in the detection box body. The device further comprises the liquid medicine sprayer, a liquid medicine tank and an air compressor. According to the invention, the air compressor and the liquid medicine tank can provide stable liquid medicine spray; the spraying process is carried out in the detection box body, so that the weighing of the weighing machine is not influenced; in addition, the weighing machine hangs the droplet holding part at the upper part of the detection box body through the bending rod, so that the influence of shaking of the droplet holding part can be eliminated; and thetime for waiting for stable reading of the weighing machine can be reduced by using the system for detection, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of pesticide performance testing, in particular to a pesticide droplet retention performance testing system and testing method. Background technique [0002] The application of pesticides in modern agriculture is one of the most effective measures to prevent pests, weeds and rodents. In my country, 70% of pesticides are used by spraying in the prevention and control of pests, weeds and rodents, including ground spraying machines, manned plant protection aircraft and plant protection drones Spraying; at this time, the retention capacity of pesticide solutions with different physical and chemical properties on the surface of different plants is not the same; because the retention capacity of various plants to different pesticide solutions is not clear, it can often be seen that the amount of pesticide solution sprayed exceeds The maximum retention capacity of the target plant surface is lost and a large amount i...
