摘要
盆栽试验结果表明:施用钢渣降低了土壤水溶态硅、DTPA-Fe、DTPA-Mn的含量,其效果随钢渣用量的增加而更为显著。但在钢渣用量一定时,却以中等粒度(60目)处理降低程度最大。施用钢渣还可以提高水稻植株体内硅的含量,降低水稻植株体内铁和锰的含量,其效果随钢渣用量增加或粒度变细而更为明显。
The results showed that compared with the control, the contents of the water-soluble-Si, DTPA-Fe and DTPA-Mn decreased and the change was in accordance with the increase of the amount of slag application, but that of the 60 mesh treatment decreased most significantly when the slag were equal in amount. The contents of silicon in plant increased,but the contents of iron and manganese decreased. The change was related to the amount of slag application or the particle size of the slag.
