Abstract:3.0%以内。This paper developed a mixing pesticide device, a differential pressure flow meter, and a flow metering valve, with the corresponding control system, to achieve variable rate spraying based on online mixing pesticide. Variable rate spraying was implemented by using the system to measure flow of water and pesticide, and control chemical flow in real time. The experimental results show that the errors of the flow meter are within ±2.0%, and the controlling errors of chemical flow are within ±3.0% in this system.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
