摘要
土壤含水率对作物生长起着极其重要的作用,目前已经有多种方法来检测其数值。主要分析和比较现有几种土壤含水率的测量方法,根据它们的优缺点,合理选择测量方法,将其推广使用,合理灌溉,节约水资源,能提高作物产量。
Soil moisture content plays an important role in crop growth,and there are several ways to detect its values. This paper analyzes and compares the existing method for measuring soil moisture. According to their advantages and disadvantages,reasonable measuring methods are selected. The method is promoted to use and reasonably irrigated,thus it can save water resources and improve crop yields.
