#$%^&*AU2020100749A420200625.pdf#####ABSTRACT The present invention discloses an intelligent supplementary grassland irrigation system, and belongs to the field of herbage moisture management. A soil moisture sensor indicates a 5 moisture shortage status of soil, and a main controller calculates an appropriate irrigation time and irrigation amount based on a water-requiring property of herbage and a recent weather status, and when the moisture shortage status is lower than a specified water content threshold, controls opening a corresponding water pump and a valve on an irrigation pipe, and conveying irrigation water to a corresponding irrigation device for irrigation. In an irrigation process, a 10 water meter measures an irrigation amount, and when an irrigation amount is reached, the controller closes the water pump and the valve, stops irrigation, and continues to monitor a soil moisture status for next irrigation. Control in the system is transmitted by using a wireless module. The intelligent supplementary irrigation system can run automatically for a long time, thereby improving an automation level of herbage irrigation. 11DRAWINGS 22 18 8 15, 16 22 17 5 20 6,7 19 23 13 14 2 P"1 )l FIG.1
