摘要
通过对 SMP- 0 1型土壤水分传感器在 3种土壤质地 (砂土、壤土、粘土 )在不同土壤水分含量下对应的传感器输出的测试 ,分析比较研究其对应的拟合曲线 ,进行率定 ,并同时研究了传感器对酸性土、盐碱土的测试情况。实验结果表明 SMP- 0 1土壤水分传感器在各种性能上都能满足农业上对于测定土壤水分的精度要求 。
Study on the output of the SMP 01 Soil Moisture Probe in three typical soil texture (sand soil, loam, clay) and variant soil moisture was conducted. Its calibration was carried out by analyzing and comparing the fitting curve of correspondence and test on the properties in acid soil and saline alkali soil. Experimental results show that the properties of SMP 01 soil moisture probe used in agriculture can meet demands of the precision requirement.
