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.

Description

technical field [0001] The present invention relates to the technical field of agricultural intelligent equipment, in particular to a test water stress control irrigation system and its data calibration method, in particular to a test water that can improve water use efficiency and can diagnose in real time, fixed-point positioning, timely and appropriate amount, and prescription water supply Stress control irrigation system and its data calibration method. Background technique [0002] At present, the development of water-saving irrigation and the improvement of water use efficiency are the key ways to alleviate the shortage of water resources and ensure food security. The comprehensive promotion of agronomic water-saving technologies, that is, the promotion of high-efficiency and precise water-saving technologies in vegetable fields, water-saving technologies in dry farming, water-saving field crops, and integration of water and fertilizers, is an important means to ensure...
