摘要
通过不同的试验设计 ,三年间对风沙土进行秸秆等有机物料培肥 ,研究其结合态腐殖质中富里酸与胡敏酸含量的变化。结果表明 ,不同的有机物料培肥均能提高风沙土松结态、稳结态富里酸的含量 ,处理间胡敏酸含量的变化不十分明显 ,但胡敏酸与松结态、稳结态腐殖质的比值 ,随着培肥年限的增加 ,与 CK处理比较 ,有降低的趋势。松结态、稳结态腐殖质中胡敏酸与富里酸的比值 ,与 CK处理比较 ,也呈降低趋势。经统计分析表明 ,以处理低量麦秸 +泥炭全肥 +泥炭效果最好。
Three years experiments were conducted to study the effects of organic matter application on Fulvic acid and humic acid of combined humus forms in wind blown soil.The results indicated that different organic matter could improve the contents of fulvic acid in loosely combined humus and stably combined humus,and the contents of humic acid were no obvious difference among all the treatments,but the ratio of humic acid to loosely combined humus and stably combined humus were declined by compared with the treatment of CK.the same as the ratio of humic acid to fulvic acid in loosely combined and stably combined.It concluded that the effect of straw+muck+peat was the more effective than that of the other treatments.$$$$
