研究了LNW-50C型中子仪在江西省余扛县刘家站中国科学院红壤生态实验站茶园等实验地上测定水分标定曲线的方法。测定了0～200cm各层土壤含水量与中子计数的关系,将中子测水结果与经典的重量法进行了比较,以重量法为基准,实际制作标定曲线和确定使用范围。
The method of LNW-50C neutron meter was used to measure the water calibration curves on the experimental sites of tea plantations such as the red soil ecological experiment station of Chinese Academy of Sciences in Liujia Station, Yuzhang County, Jiangxi Province. The relationship between soil water content and neutron counting at 0 ~ 200cm layer was measured. The result of neutron water measurement was compared with the classical gravimetric method. Based on gravimetric method, the calibration curves were actually made and the scope of application was determined.
