摘要
研究结果表明 ,红壤团聚体的力学稳定性与其粒径和化学组成有关 ,粒径越小 ,土壤中粘粒和游离氧化铁含量越高 ,其力学稳定性越大 ;在 p H3.0~ 6 .0范围内 ,p H的变化对团聚体的稳定性影响不大 ,因此因农业措施引起的 p
Results of laboratory experiments showed that mechanical stability of red soil aggregate was related with their size and chemical composition and increased with decrease of the size and increase of clay and free iron oxide contents Effect of pH on aggregate stabality was slight when pH was within a rang from 3 0 to 6 0,this might be suggest that small change of pH induced by agricultural measures could not make obvious effect on soil aggregates
