Pipette

In order to compare PSD difference in measurements by LD method and pipette method in black soil region,178 soil samples collected from various layers of 36 soil profiles were analyzed by LD method and traditional pipette method.

目前激光衍射法(laser diffraction method,LD)逐步被用于土壤颗粒粒径分布(particle size distribution, PSD)的分析,为了对比LD法和吸管法测定东北黑土区土壤PSD的差异性,采用LD法和吸管法分别对东北黑土区宾州河流域36个土壤剖面不同层次178个土壤样品的PSD值进行了测定与分析。
