  1. 一、背景与意义

  2.    三种估算葡萄园耗水方法的对比研究 Zhang and Kang, 2008, Agricultural and Forest Meteorology, 148: 1629-1640.

  3. 三种估算葡萄园耗水方法的对比研究 葡萄全生育期瞬时潜热通量估算值与实测值之间的相关性统计分析 • P-M模型高估了2006年葡萄园潜热通量，而低估了2007~2008年的潜热通量。与P-M模型相比，S-W和C模型的估算精度有一定提高，但S-W高估了葡萄园潜热通量。

  4. 二、发展态势与热点问题 利用植物生理监测系统进行精量控制用水

  5. 灌溉方式改变 植物生理反应 作物WUE 局部干燥区域的根信号能帮助改变 作物的气孔开度和调节水分消耗 DRY WET WET DRY

  6. 部分根系分区交替灌溉 不同根区湿润方式的玉米根系生长状况 全部根系均匀灌溉 固定部分根系灌溉
