电容式土壤温度、水分、盐分三参数传感器率定
2020
Overview
【目的】检验温度、水分、盐分三参数传感器（SMEC 300）测定土壤含水率、电导率的精度。【方法】在天津农学院西校区农田水循环试验基地进行了土壤含水率与电导率的率定试验。试验设置3种供水水平（2.65、3.25、3.80 kg）和4种盐分水平（加盐量0、20、70、100 g）以及6种矿化度梯度（1、5、10、15、20、25 g/L）。布置6个盆，每盆内干土质量为8.85 kg，土层厚度为10 cm，传感器埋置于土面下5 cm处，试验期间定期称取盆的质量，由此测得土壤实际含水率；电导率率定试验也布置6个盆，盆内加水8 L/盆，盆内放置4个传感器，每40 min测试1个处理，利用数据采集仪获取传感器数据。分别对土壤含水率和电导率进行率定。【结果】传感器测定的电导率与矿化度呈显著的指数关系，相关系数均在0.92以上；土壤盐分影响土壤含水率的率定，实际含水率与传感器测定的土壤含水率和电导率呈二元线性关系，相关系数最大为0.940 4，最小为0.601 9，均达到了显著或极显著水平，不同传感器的率定参数有较大差异。【结论】电容式土壤温度、水分、盐分三参数传感器有其对应的参数，应逐个传感器进行率定。
