摘要
通过对河西走廊临泽北部绿洲春小麦蒸发蒸腾定量测定,分析了春小麦不同生长发育阶段的实际耗水量和耗水特征。根据春小麦水分利用效率的变化,探讨了产量与耗水量的非线性关系,为确定合理的农田灌溉制度和节约用水提供了科学依据。
The quantitative determination of evaportranspiration of Spring wheat in the oasisof the northern part of Linze of the west of the Yellow River was conducted,and at thesame time,the actual water consumption and its charactristics of spring wheat was anal-ysed in its different development stages.Based on the variations in water use efficiencyof spring wheat,the non-linear relationship between wheat yields and water consump-tion is also discussed so as to provide the scientific base for the establishment of rationalirrigation schedules and water-saving use.
