以污泥干化芦苇床运行2年和自然稳定1年后的稳定化污泥为肥料，进行污泥农田肥效试验。试验分时期考察了大豆作物在不同污泥配比下的生长趋势，包括植株高度、果实产量及果实营养成分等。试验共设定6组，污泥和土壤的配比分别为1∶8?0，1∶5?0，1∶3?5，1∶2?6，1∶2?0及空白组。每组设10个平行样，共60株。试验结果表明：大豆株高与污泥浓度呈正相关，大豆产量及果实营养成分也与污泥浓度有关，适当的污泥浓度可以促进大豆增产并增加其营养成分含量，但污泥浓度超过一定限度以后，产量及营养成分有所下降。

Using stabilized sludge of two?year sludge drying reed beds and that of one?year natural stabilization as manure, sludge fertility in farmland was studied. Soybean growth trends, including plant height, grain yield and grain nutrients under different sludge ratios were investigated. Sixty plants were divided into 6 groups averagely, and ratios of the sludge manure and local soil were 1 ∶8?0, 1 ∶ 5?0, 1 ∶ 3?5, 1 ∶ 2?6, 1 ∶ 2?0 and ck, respectively. The results showed that it is feasible to recycle stabilized sludge as manure. Furthermore, plant height is proportionate to sludge manure content. Proper concentration of sludge manure can enhance yield and nutrients of soybean, howev?er, excessively high concentration will decrease them obviously.
