黄淮海中部地区作物水分胁迫和干旱研究结果

 根据河南巩县和山东泰安不同水分处理的冬小麦和夏玉米的农田试验资料，分析了两种作物的耗水规律，确定了最佳耗水量，求出干旱指标，阐述了农田水分变化规律，从提高水分利用效率和经济效益出发，制订了冬小麦的优化灌溉方案。事实表明这种优化灌溉方案能节约用水，对缓解水资源的紧张局面有重要意义。

STUDIED RESULTS OF CROP WATER STRESS AND DROUGHT IN CENTRAL REGION OF HUANG-HUAI-HAI PLAIN

The experimental data of different soil water treatments of winter wheat and summer maize in Gongxian County, Henan province and Taian City, Shandong province were used to analyse the law of water consumption of crops, define optimal water consumption, develop drought indexes of crops, expound the law of field water change,work out optimal irrigation scheme of winter wheat from the view.point of raising water use efficiency and economic benefit. Facts indicate that the optimal irrigation scheme is able to save water and has important sense for alleviating water resource deftcit.
