用回归方程计算土壤质地
ESTIMATE THE QUALITY OF SOIL BY REGRESSION EQUATION
【摘要】 本文根据土壤质地与样品密度间的相关性。用回归方程计算土壤粘粒含量,实验结果优于手测法(指感法)。而又较吸管法和比重计法简便。
【Abstract】 This paper estimates the quantity of soil sticky particles by means of regression equation according to the correlation betwean quality of soil and density of Sample. The experimental result is better than hand test method(fingers feeling method), and simpler than the method of specific gravity meter.
