中文摘要：

以棉花为试验材料,采用室内试验和理论计算的方法,以水分为控制因子,以土壤水分动态变化情况为研究对象进行研究。结果表明,土壤表层水分运动较为剧烈;土壤含水率与植物根系吸水率在一定范围内呈正相关;以土壤水分动态资料建立根系吸水模型可为棉花种植建立合理的灌溉制度提供理论依据。

英文摘要：

Using the method of indoor test and theoretical calculation, with water as the control factor and soil moisture dynamic change as the research object, the dynamic changes of soil moisture of cotton under different water treatments conditions were studied during pot test device. The results showed that, the soil surface water movement was more intense; Within a certain range of soil moisture and plant roots showed a positive correlation with water absorption; Root water uptake model based on soil moisture dynamic data could provide a theoretical basis for cotton planting to build a rational water-saving irrigation system.
