摘　　要：盆栽试验施用两种由磷、氮含量较高的化学镀镍废液沉淀除镍之浓缩液制成的复合肥。结果表明,芥菜施用浓缩液复合肥后,肥效与对照的“过磷酸钙”复合肥无显著差异;与不施肥相比,由于芥菜幼苗耐肥性较差,在一定程度上抑制芥菜的前期生长,芥菜地上部干质量显著降低,但对提高土壤Ｎ、Ｐ、Ｋ含量仍有显著帮助。The pot experiment was carried out to study fertilizer effects of two kinds of compound fertilizers that were made of Ni-removal concentrated liquor from spent electroless nickel solution, which the concentrations of phosphorus and nitrogen were high, on the mustard and changes of the nutrients in the soil. The results showed that fertilizer effects of two concentrated liquor compound fertilizers on the mustard were not significantly different with that of superphosphate compound fertilizer. Compared with the no fertilizer treatment, the growth of mustard had been restrained during the sprout stage because of its bad fertilizer-patient, and dry weight of mustard biomass were remarkably decreased. But concentrated liquor compound fertilizers could remarkably increase contents of NPK in the soil.
