The northwest hilly area of China is relatively arid,and the efficiency of drip irrigation is low.In order to realize the efficient irrigation of agricultural crops in hilly and mountainous areas,the study designs a small a integrated water and fertilizer drip irrigation machine,uses a small gasoline engine to drive the pump.PLC controls the flow by controlling the electric flow regulating valve.The liquid level device feedbacks the liquid level of the water storage bucket and the fertilizer bucket,and realizes the fixed mode drip irrigation and manual adjustment drip irrigation by operating the touch screen.The experiment shows that the sprinkler can carry out automatic drip irrigation and manual drip irrigation.The drip irrigation error is small,and it is suitable for drip irrigation in hilly and mountainous areas.
