Experimental water stress control irrigation system and its data calibration method

Abstract

The invention relates to agricultural intelligent equipment technology, in particular to a water stress control irrigation system and a data calibration method of the water stress control irrigation system. The water stress control irrigation system is used to provide water to a cultivation device. The cultivation device includes a head device and an irrigation device. The head device includes a data acquisition unit, a stress irrigation control unit and a water supply control unit. The data acquisition unit is used to collect water content and total irrigation water of the cultivation device. The stress irrigation control unit is used to calculate needed irrigation volume in accordance with data information collected by the data acquisition unit and upper limit value and lower limit value of default irrigation amount. The water supply control unit is used to control irrigation time and irrigation amount of irrigation device, according to the needed irrigation volume. The data acquisition unit can constantly monitor the water content of the cultivation device and is with data calibration algorithm to get optimal irrigation amount. The data calibration method of the water stress control irrigation system is accurate. The water stress control irrigation system changes single measurement mode and meets the need of water stress experiments of different gradients.
