| 摘 要： | 对内蒙古退化典型草原围封恢复系列进行研究,测定了不同围封年限下的栗钙土物理性状.结果表明,(1)随着围封年限的增加,土壤紧实度逐渐下降,土壤密度变小.孔隙度增大,土粒密度基本不变.土壤机械组成中:粘粒、粉粒含量增加,沙粒含量下降.(2)通过Duncan方差分析,发现围封10a左右是土壤以上物理性状的分界点.

| Abstract: | The paper studied the dynamic effects of exclusion on the physical properties of the typical chestnut soil of a fencied degenerated typical leymus chinesis steppe in Inner Mongolia.The result showed:(1)While the fencing time lasts longer,the degree of compactibility of the soil gradually becomes week,and density of the soil declines.The soil porosity tends to increase while the soil specific weight stays unchanged.The changes of the soil texture are characterized by the increases of silt and clay,and a decr... |
