| 摘 要： | 针对目前土壤水分传感器室内标定时很难得到含水率均匀的土样,设计了一种试验装置和测试方法。通过一系列室内试验,对3种土壤水分传感器进行了测试和标定。结果证明,这种方法对于短探针土壤水分传感器的标定切实可用,同一种传感器在不同质地土壤中标定曲线不同,给出了3种传感器在砂土、壤土、粘土中的标定曲线,并分别从线性度、敏感度、稳定性等方面对3种土壤水分传感器进行了分析比较。

| Abstract: | A test apparatus and test methods were designed to solve the problem that it was difficult to get uniform water content soil samples to indoor calibration of soil moisture sensors.The test results showed that this method for the calibration of the short probe soil moisture sensor could be used effectively.The calibration curves for the same sensor in different soil textures were different.The calibration curves of the three sensors in the sand,loam and clay were derived.The three soil moisture sensors were analyzed and compared from the linearity,sensitivity,stability. |
