AI Technical Summary
Existing fertigation systems lack dynamic concentration adjustment under conditions of multi-crop planting or zoned irrigation, resulting in concentration lag, uneven mixing, and irrigation interruption during the irrigation process, which affects the uniformity of crop absorption.
The fertilizer tank adopts a three-chamber layered structure, combined with a concentration monitoring device and a liquid level monitoring device. Through the control system, the fertilizer and water are dynamically adjusted in real time to ensure that the concentration reaches the set value quickly, continuously and accurately during irrigation.
It achieves closed-loop automatic adjustment of concentration during the irrigation process, improves mixing efficiency and concentration response speed, ensures stable discharge and adaptability to multiple crop irrigation, and enhances water and fertilizer utilization and system automation level.
