| 摘 要： | 该文针对时域反射法（TDR）、频率分解法（FD）型土壤水分传感器和中国农业大学研制的基于驻波率原理（SWR）的新型土壤水分传感器，在德国北部典型的沙壤土、黄土、含煤沙土及含铅壤土土样上做了试验.根据采集的数据进行方差分析，结果表明:SWR型土壤水分传感器是一种高精度、高可靠性、受土壤质地影响不明显的快速土壤水分测量传感器，其性能可与世界先进TDR型和FD型土壤水分测量传感器相媲美.

| Abstract: | Soil moisture sensors based on principles of Time Domain Reflectometry(TDR),Frequency Domain(FD) and a new type of soil moisture sensor based on Standing Wave Ratio(SWR) developed by China Agricultural University were evaluated with typical sandy loam,loess,peaty sand and leady loam from northern Germany.An analysis of variance of the experimental data suggested that the SWR soil moisture sensor has the highest precision,the greatest dependability and is influenced only slightly by soil quality. SWR-based sensors' performance is compared favorably to TDR and FD soil moisture sensors. |
