摘　　要：土壤含水量是非充分灌溉研究中的一项重要指标,以冬小麦作为研究对象,基于实时的土壤含水率监测数据,运用Irrimax软件对监测数据进行分析,对土壤含水量、作物根系范围等参数进行了确定,并对灌溉管理系统的经验数据进行了修正。本方法可快速准确地分析冬小麦生长过程中作物计划湿润层实时的含水量和根深等参数,从而为制定实时的灌溉制度提供基础数据和科学依据。The soil water content is an important indicator in the study of non-sufficient irrigation.Based on the real-time soil moisture monitoring data,winter wheat is chosen as research object,the Irrimax software is used to analyze those monitoring data,and the parameters of soil moisture and crop root scope are analyzed in this paper.In the end,the analysis results are used in the irrigation management system.The method can analyze the real-time soil water content and root range fast and accurately,which will provide basic data and scientific basis for the real-time irrigation system.
