摘　　要：掌握农田系统作物耗水量变化情况,对研究作物各生育期水分消耗规律至关重要。基于此,本数据提供了中国农业大学石羊河实验站内大型称重式蒸渗仪实测的玉米耗水量数据,时间分辨率为日尺度,灌溉方式为畦灌,数据范围为2009–2016年。数据采集和处理过程严格遵循仪器数据质量控制和规范。数据以日为尺度公开,以期为区域农业水资源高效利用提供依据。A good understanding of the variation in crop water consumption in farming systems is essential for studying the patterns of water consumption by crops at various growth stages.Based on this,this dataset provides the maize evaporation and precipitation intensity data measured by a large-scale lysimeter at Shiyanghe Experimental Station of China Agricultural University from 2009 to 2016,with a temporal resolution of daily scale.The irrigation method is border irrigation.The data acquisition and processing process strictly follows the instrumental data quality control and specifications.After data processing,quality control and evaluation,the data are made public on a daily scale with a view to providing a basis for the efficient use of regional agricultural water resources.
