摘要 本文探讨了利用深层锂玻璃中子土壤水分仪加高含氢反射体测量0—20cm表层土壤水分,试验结果证明有良好的线性相关系数,与深层土壤测得的容积含水量值误差范围一致,基本能满足生产要求。 A method of determing moisture of soil surface layer (0-20cm) by a subsurface neutron gauge with a Li-Glass detector was introduced. A hydrogeu-rich reflector was put on the surface. The results were shown to have a good linear correlation and a reasonable deviation, therefore the technique could be used in practice.
