基于蒸发量的膜下滴灌棉花灌溉预警装置设计与试验（Design and Experiment of Scheduling Irrigation Device Based on Pan Evaporation for Drip-irrigated Cotton under Plastic Mulch）
棉花 灌溉预警 蒸发 膜下滴灌
2010/12/29
设计了一种基于蒸发量的简易灌溉预警装置，并建立了基于水量平衡原理的灌溉预警模型。通过田间试验，确定了适宜供水条件下新疆膜下滴灌棉花各生育阶段的蒸发皿—作物系数，并建立了适宜的灌溉预警指标，提出了降雨条件下的指标修正方法。田间应用表明，在北疆棉花膜下滴灌条件下，苗期、蕾期、花铃期和吐絮期分别以累计蒸发量达到140、75、50和120mm来控制灌水时间，以0.15、0.4、0.7和0.25倍的累计蒸...
