摘要
2001～2002年在内蒙风沙区对春小麦全生育期正常供水条件下的棵间蒸发规律进行了试验研究,确定了不同生育阶段棵间蒸发量占同期耗水量的比例关系,分析了棵间蒸发量的日变化规律及其与表层土壤含水量的关系,建立了棵间蒸发量占耗水量的比值(E/ET)与叶面积指数LAI的函数关系式。
An experimental research on soil evaporation of spring wheat under normal water supply was conducted in an windy dusty area of Inner Mongolia from 2001 to 2002. The ratio of soil evaporation to water consumption at each growing stage of spring wheat was determined, the daily variation of soil evaporation and the relationship between soil evaporation and surface soil moisture were analyzed, and the relationship function between the ratio of soil evaporation to water consumption (E/ET) and leaf area index (LAI) was established.
