An agricultural plant protection apparatus (20, 30, 40, 50) includes a container (201) for holding liquid, one or more pipelines connected with the container (201), each pipeline includes a nozzle (2021), a pipeline (2022) for connecting the nozzle (2021) and the container (201), and a valve device (2023) is installed on the pipeline (2022) for regulating the liquid flow in the pipeline (2022); Each pipeline also includes a sensor (2024) for detecting the state information of the liquid flowing to the nozzle (2021) in the pipeline (2022), and a controller (2025) electrically connected with the valve device (2023) and the sensor (2024). The controller (2025) is used to automatically control the valve state of the connected valve device (2023) according to the state information of the liquid sensed by the sensor (2024), so as to control the spray flow of the nozzle (2021). It realizes the automatic control of each pipeline in agricultural plant protection equipment (20, 30, 40, 50) and improves the precision of spraying. And improve the accuracy of spraying. And improve the accuracy of spraying. And improve the accuracy of spraying< br/>
