摘要
采用污泥堆肥用于农作物方法,研究污泥农用对作物及土壤环境的影响。在田间施用消化污泥、污泥堆肥与污泥肥料1年。结果表明,各处理玉米均比对照显著增产,并且使土壤养分情况得到改善,对土壤和作物没有明显的重金属影响,说明消化污泥、污泥堆肥、污泥肥料与化肥和其他有机肥一样,是一种常效肥,但对土壤和地下水的长期影响应作进一步的研究。
Using the inactivated sewage sludge,the sewage sludge compost and the fertilizer for a year,compared with the control,the corn production increased evidently,and the activity of soil enzyme increased,too,no obvious heavy metal effect on soil and crops,which showed that the inactivated sewage sludge,the sewage sludge compost and the fertilizer were common effective fertilizer as the chemical fertilizer and other organic fertilizers,but the long effect on soil and groundwater should be studied ulteriorly.
