| 摘 要： | 以长期定位试验为基本材料 ,研究了 9年连续施用有机肥对紫色水稻土铁、锰、铜、锌形态的影响。结果表明 ,有机肥是土壤铁、锰、铜、锌的良好给源。紫色水稻土长期施用有机肥与单施化肥比较 ,土壤中的全铁、全锰变化不大 ,全锌提高了 5.5%～ 30.0% ,交换态铁、碳酸盐结合态铁、有机态铁、无定形结合态铁分别提高了1.5%～12.7%、2.4%～8.9%、11.6%～19.5%、32.5%～72.5%。锰、锌的各形态数量均有不同程度的增加。同时 ,长期施用有机肥增大了土壤铜的消耗 ,全铜含量有下降的趋势。

| Abstract: | Effect of nine year using manure continuously on the form of Fe、Mn、Cu、Zn of purple paddy soil were studied with long term fixed location experiment as the base materials. The results showed that manure is the better source of Fe、Mn、Zn of soil,and according to the comparison between the samples manure with organic fertilizer and that manure with pure chemical fertilizer the total Fe and Mn changed very little, total Zn increased by 5.5%～30.0%, exchanging form Fe by 1.5%～12%, carbonate binding form Fe by 2.5%～8.9%, organic binding form Fe by 11.6%～19.5%, amorphous form Fe 32.5%～72.5%. Each form of Mn and Zn increased by different degrees. In addition, the consumption of soil Cu increased and total Cu occurred tendency to decrease. |
