| 摘 要： | 通过分析定点埋设的SWR-2型土壤水分传感器采集的土壤水分数据,分析了农田土壤水分信息的时空变化规律及不同深度土层含水率间的相关关系。结果表明,冬小麦和夏玉米生长条件下农田土壤剖面适宜埋设的探头数目为1～4个,并提出了相应的水分探头布设方案及数据处理技术。

| Abstract: | Based on the observation data of the SWR-2 type soil moisture probe laid at fixed point,the variation of soil moisture information in time and space and correlation of soil water content in different depths was analyzed.Results shown that the accurately number of soil moisture probe in soil profile during growing season of winter wheat and summer maize was 1 to 4,and the layout scheme of soil moisture probe in soil profile and data processing technology proposed. |
