摘要

施用粪肥引起农田氮、磷流失的增加已引起人们广泛的关注。为了解粪肥中添加明矾可否降低农田污染物的流失

采用化学分析与田间试验相结合的方法研究了添加明矾对粪肥中水溶性养分和重金属浓度及施粪肥后农田养分、重金属流失的影响。结果表明

粪肥中添加明矾可大大降低其中的水溶性P和重金属浓度

其中水溶性P的下降幅度达79.3%。添加明矾后

粪肥施入农田形成的径流中P和重金属浓度明显低于不添加明矾的处理。但添加明矾对农田可溶性总N、NO3-N和NH4-N流失的影响不大。粪肥中添加明矾不会引起地表径流中铝浓度明显增加

对蔬菜产量影响不明显。

Abstract

It is concerned that animal manure application to soils have been shown to result in relatively high nutrient runoff.In order to understand whether the addition of alum(aluminum sulfate) to the manure decreases runoff loss of pollutants from soils

a field experiment was carried out to study the effects of alum addition to manure on water soluble nutrients and heavy metals in the manure and runoff losses of nutrients and heavy metals from the field applied with animal manure.The results showed that alum addition to manure could decrease significantly the solubility of P and heavy metals in the manure.Water-soluble P in the manure treated with alum was 79.3% lower than that in the manure without alum treatment.Addition of alum to manure decreased significantly the concentration of P and heavy metals in runoff from field applied with manure.However

addition of alum to manure did not have significant effects on the concentration of total soluble N

NO_3-N and NH_4-N in runoff.Also

alum addition did not change significantly loss of Al in runoff from the experimental field and yield of vegetable.
