自动土壤水分观测站业务化检验分析

土壤水分监测对农业生产和科学研究都具有重要意义,自动土壤水分观测数据得到了广泛应用,实现了土壤水分的自动监测。通过对天津新建DZN3型自动土壤水分观测站业务化检验过程进行介绍,分析了自动观测数据的到报率和土壤常数的测定,并对人工与自动观测数据做了详细的对比分析,通过两个实例分析了对比检验的方法,确定了能够业务化运行的自动土壤水分观测站,分析了站点未通过检验的原因,并对重新进行业务化检验的站点和日常维护提出了建议,介绍的方法为今后开展相关业务化检验奠定了基础。

Operational Inspection of Automatic Soil Moisture Observation Stations

Soil moisture monitoring plays an important role in agricultural production and scientific researches, so automatic soil moisture measurements are widely applied. The operational verification process of the new DZN3 type automatic soil moisture station is introduced. The report rate of automatic observation data and the determination of soil constant are analyzed and compared with the manual observation data in detail. Automatic soil moisture observation stations that can put into operation are confirmed through the way of contrast testing. The reasons for failing to pass the test are also analyzed, and some suggestions are given for future operational tests.
