中文摘要: 《农业气象观测规范》规定：应用中子仪测定土壤湿度前必须进行田间标定，在实践中发现其标定方法时间局限性强，工作难度大，且存在客观误差，而采用分段标定时间，改变标定地点的方法，有效地解决了上述不足。
中文关键词: 中子仪,田间标定,改进方法
Abstract:In the Agriculture Meteorological Rule, it was prescribed that the field calibration must be done before the soil moisture is measured by the Neutron Soil Moisture Meter. It was found in practice that calibration method is very difficult and has a time limitation and objective error. The questions can best be solved with dividing calibration time and changing calibration place.
