摘　　要：[目的]研究基于Globe-Logging TDR系统的棉花土壤水分与温度的变化规律。[方法]在棉花土壤中分10、20、30以及40 cm土层深度水平埋装一根Globe-Logging TDR测量探针,通过无线网络在线监测7月棉花土壤水分和土壤温度的变化规律。[结论]在不降雨或不灌水的情况下,深层土土壤水分要高于浅层土,深层土的土壤含水率与土壤温度呈反比例关系;当土壤温度高于最低气温时,土壤温度随着土层深度的增加而升高。[结果]该研究可为Globe-Logging TDR系统的推广应用提供参考。[Objective] The aim was to study the variation of soil moisture and soil temperature in cotton field based on the Globe-Logging TDR system.[Method] Installing horizontally a Globe-Logging TDR measuring probe in the soil depth of 10 cm,20 cm,30 cm,and 40 cm in cotton field,soil moisture and soil temperature variation were monitored by the wireless network online in July.[Result] Under the condition without rainfall or irrigation,the deep soil moisture was higher than the shallow soil,and the deep soil moisture content and soil temperature were in inverse proportion.When the soil temperature was above the minimum temperature,the soil temperature increased with the increase of soil depth.[Conclusion] The research provided a reference for the popularization and the application of Globe-Logging TDR system.
