在河西绿洲生态条件下，研究了污泥的施入方式及施用量对于小麦生物性状及其产量的影响。结果表明，污泥施用量为9 000 kg/hm2、复种绿肥还田处理下的小麦籽粒产量和生物产量表现最好。相对于常规纯施化肥处理，施入污泥处理可以改善小麦的生物性状。

The effects of dosage and way of sludge application on the biological characters and yield of wheat are studied under the ecology condition of Hexi Oasis. The result shows that the wheat grain yield and biological yield performed best when the dosage of sewage sludge is 9 000 kg/hm2、 multiple cropping green manure treatment. Compared with the conventional pure chemical fertilizer processing， applied sludge treatment can improve the biological characters of wheat.
