摘要
通过武威地区多站点、多年份、多种方法的灌溉试验成果，阐述了沙漠绿洲区春小麦生育期间的需水量及需水规律，并对需水量与其相关因素的关系、需水量预测预报进行了分析论述，为灌溉管理和规划设计提供了科学依据。
Based on the results of the experimental irrigation study by using different methods in the different sites of Wuwei district from 1982 to 1988,the water demand and its regulation of spring wheat during its growing period in the oasis of desert are discussed.The relationship between the water demand and some relative factors and water need forecast and predication are demonstrated too.This study provides the evidence for the spring wheat irrigation management and programme design in Wuwei district.
