In this paper, based on the fact that is still a small peasant economy in China and there are many small plots, this article studies small and medium sprayers. In this sprayer, the subdivision precision spraying control system, designed for precision agriculture applications, was simulated by the LabVIEW software, while an experimental setup was able to measure and record during laboratory experiments. The main pipeline of sprayer chose the A and B. And the two different pipelines were set in the different target spray volume. When the theoretical spray value was kept being unchanged, the flow rate was verified with the field sprayer speed which were set by the pulse generator. With that the pressure stability test was completed. Based on the analysis and experimental results, the flow control precision is 97.03%, and the pressure stability precision is 97.88%, the relative average of the pulse generator is 0.05. Finally, the subdivision system could control the flow of the two branches and was better than the traditional spray method in China, while it could achieve more precise control of spray.
