摘要
用环刀法分3个不同坡位和4个土层深度对广西大青山米老排人工林土壤体积质量、含水率、持水量、孔隙度等物理性质进行了研究,结果表明:大青山米老排人工林土壤体积质量、土壤水分及土壤空隙的差异主要体现在表土层上,表层以下各土层之间差异不显著;不同的坡位对米老排表土层的土壤物理性质影响显著,但对表层以下其他土层无显著影响。
The soil bulk density,soil water content,soil water holding capacity,soil porosity and other physical properties of four layers in three slope positions in MytiLaria laosensish plantations in Daging mountain were studied.The results showed that the differences of soil bulk density,soil moisture and soil porosity were mainly existed in the soil surface layer between the positions and no significant differences in the deeper layers.The slope positions had significant differences on soil surface physical properties will not on the other deeper layers.
