摘要
文章通过扫描电子显微镜得到试样的SEM图像。定性分析了草炭土水平方向和竖直方向孔隙形态不同,水平方向孔隙杂乱无规则,竖直方向孔隙条状分布,土壤团聚颗粒以线对面接触方式为主,主要矿物成分为伊利石。结合IPP软件定量分析得到草炭土水平方向观察面与竖直方向观察面的孔隙率、孔隙面积、孔隙数量、孔隙扁平度和分形维数皆有差异,通过对草炭土微观结构特性研究,掌握了草炭土微观结构特性,可以更好地利用草炭对植物的生长,对绿色环境起到重要的作用。
SEM images of the samples were obtained by scanning electron microscopy.The horizontal and vertical pore forms of peat soil are different.The horizontal pore is disorderly and irregular,while the vertical pore are in strip distribution.The soil agglomeration particles are mainly in line-to-face contact mode,and the main mineral composition is illite.Based on the quantitative analysis of IPP software,the porosity,pore area,pore number,pore flatness and fractal dimension of the horizontal and vertical observation surfaces of peat soil are all different.
