| 摘 要： | 为了筛选黄淮海地区适宜的墒情监测设备，通过大田试验研究了中子仪、Diviner2000、Trime以及swr-2观测了作物生育期内的土壤水分变动，同时利用取土烘干法对仪器进行标定，并以烘干法的观测结果为标准，分析不同墒情监测设备的测量精度，试验结果表明，中子仪的观测精度最高，其他3种仪器观测精度基本相当。

Accuracy Analysis of Measurement Results with Different Soil Moisture Monitoring Equipment |
| |
| Abstract: | In order to selection suitable soil moisture monitoring equipment in huang-huai-hai plain in China. The field experiments were conducted during 2012, the soil moistrue content were observated with intelligent neutron probe, Diviner2000, Trime, swr-2, at same time observed soil moisture with drying method. At last analysis measurement results of intelligent neutron probe, Diviner2000, Trime and swr-2 based on the measurement results with drying method. The result shows that the highest accuracy is intelligent neutron probe. |
