To grow crops in areas with arid climates, porous karst soils, or increasingly unpredictable seasonal droughts, farmers struggle for their yield and spend precious water resources on irrigation. This ecological and economic problem of excessive water usage in agriculture may be alleviated by application of precision irrigation techniques. Precision irrigation implies precise spatial and temporal control of water supply based on the actual water demand. This is also critical for maximizing the yield-quality of cultivars like grapevine, which dynamically change their water requirements throughout different parts of their vegetative season [1].

作物有多渴：用于基于植物的田间水分胁迫测量的新兴仪器

为了在气候干旱、岩溶土壤疏松或季节性干旱越来越不可预测的地区种植农作物，农民们为提高产量而奋斗，并将宝贵的水资源用于灌溉。农业中过度用水的生态和经济问题可以通过精确灌溉技术的应用得到缓解。精准灌溉意味着根据实际需水量对供水进行精确的时空控制。这对于最大限度地提高葡萄等品种的产量质量也至关重要，葡萄在生长季节的不同部分动态改变其需水量 [1]。
