| 摘 要： | 通过分析细质沙土(河北大名县沙土区)中不同结合形态腐殖质、CEC、全 N、有效钾等多项指标,发现细质沙土有机质总量的80%以上与矿质颗粒相结合,以有机无机复合体形式存在。由于紧结态腐殖质在总结合态腐殖质中所占比例较大,故对土壤 CEC、全 N 和有效钾的影响比松结态和稳结态要大。

| Abstract: | A fine sandy soil is determined with different form humus,CEC,total N and available K.It is found that more than 80% of organic matter exists in organo-inorganic complex.Different form humus has a different role in soil.The tightly-combined humus shows much more important influence on soil CEC,total N and available K content than loosely-combined and stably-combined humus because of its large proportion in the com- bine humus. |

| Keywords: | heavy fraction loosely-combined humus stably-combined humus tightlycombined humus |
