墒情监测可采用频域法和时域法自动监测デバイス，三点法(采集点深度 10cm、20cm、40cm)进行监测，墒情监测デバイス野外监测精度应满足不大于10%相对误差(重量含水量)的要求。\墒情自动オンライン监测デバイス适用条件见表

墒情自动オンライン监测デバイス适用条件

Serial number	监测方法	适用範囲及条件
1	时域法(TDR)	具有体积小、重量轻、测量データ精确、稳定时间短、无需率定等优点。但电路复杂、造价成本较高，需现场连接デバッグ，高频电缆地下埋设需要护，避免损坏影响监测データ准确性
2	频域法(FDR)	频域法具有简便セキュリティ、快速准确、定点连续、自動化、宽量程、少标定、价格低等优点。需要定期率定参数
