摘要
结合四川土壤基层分类 ,选取四川紫色雏形土的几个土系 ,对土壤的水分发性能及其与土壤结构性尤其是机械组成和微团聚体组成的相关关系分析发展 ,土壤水分蒸发具有明显的阶段性 ;土壤水分累积蒸发量与蒸发历时之间总体上符合乘幂方程 ;土壤蒸发速度与〈0 .0 0 1mm的颗粒含量呈明显相关关系 ,与 >0 .2 5mm的大团聚体含量呈明显负相关关系。
Combining to soll basic category taxonomy of Sichuan,son\me soll series of Purple Canbisols were choosed.The soll water evaporation properties amd correlated between soll water evaporation property amd soll structure property were studied,Soll particle size distribution and soll microaggregate composition were especially discussed in this paper.Results showed that the soll water evaporation had the obvious stages.There were power relationships between soll cumulative water evapontion amd soll evaporation du...
