| 摘 要： | 对闽北6个样品测定结果表明,红壤复合胶体中C、N含量较高,其腐殖质的C/N和HA/FA、胡敏酸的芳构化度和腐殖质氧化稳定性系数均较重组小,而松结合态/紧结合态腐殖质的比值则较大.这些特性有利于土壤养分保存与供应和改善土壤结构.

Nature of humus in colloidal complex of red soil |
| |
| Abstract: | The contents of C and N in the colloidal complex of red soil was relatively high, whereas the values of C/N and HA/FA in humus, aromaticity of HA and the oxidative coefficients of humus were narrower than those in heavy fractions.However,the rate of steady C to loose C in humus was higher. |
