摘　　要：污泥中的有机质及各项营养成分在农业生产中可起到重要的肥效作用,但未稳定的污泥在农用过程中会引起作物的不良反应,从而影响作物的产量.试验中以人工湿地积存污泥为肥料,与当地土壤按不同配比掺合,同时,以水稻草焚烧后的余灰作为补充钾源,混匀制成栽培基质进行小麦的盆栽试验.通过植株的生长状况及产量较直观地探寻此类污泥农用的稳定性.The organic matter and nutrition of sludge may play an important role in the agricultural production, but the unstable sludge can induce the negative response in the process of growing,it may decrease the output of crops. In this study, take the dried sludge of constructed wetland as the fertilizer, mix with the local soil, simultaneously add straw ash as supplement source of potassium, then mix uniformly, and make the cultivation matter to the pot. Through wheat＇s growth condition and the output indicate the stability of this kind of sludge in agriculture.

关 键 词：人工湿地 农用 污泥 稳定性
