| 摘要: |
| 作为全国重要水稻生产基地的湖南,因夏秋多旱的气候特征，水稻种植经常受干旱影响而减产。为做好气象为农服务工作，湖南省气象局从2010年开始，在全省建设了60个自动土壤水分观测站，显著改进了土壤水分观测手段和方法，提升了现代农业气象业务和干旱监测服务水平。本文简要介绍了DZN3型自动土壤水分观测仪的工作原理和系统结构,在总结省、市、县三级维护保障实践基础上，重点阐述了DZN3型自动土壤水分观测仪常见故障的分析及排查,对台站日常巡查维护及有关注意事项提出了建议。为气象部门基层台站业务人员提高维护维修时效，降低故障发生概率，提供借鉴与参考。 |

| Abstract: |
| Hunan is an important rice production base in China. Due to the climate characteristics of drought in summer and autumn, rice planting in Hunan is often affected by drought, which results in reduced production. In order to do a good job in meteorological service for agriculture, Hunan Meteorological Bureau has built 60 automatic soil moisture observation stations in the province since 2010. It has significantly improved the means and methods of soil moisture observation and the modern Agrometeorological business and drought monitoring service level. In this paper, the working principle and the system structure of DZN3 automatic soil moisture observation instrument were briefly introduced. And based on the practice of maintenance and guarantee at the provincial, municipal and county levels, the analysis and troubleshooting of common faults of DZN3 automatic soil moisture observation instrument were also expounded in detail. What’s more, some suggestions on the daily inspection, maintenance and other notices were put forward, which has provided reference for grass-roots business personnel in to improve the timeliness of maintenance and reduce the probability of failure. |
