通过盆栽和大田试验 ,初步探讨了污泥复合肥种植小麦的肥效及其对小麦重金属吸收的影响。试验结果表明 ,污泥复合肥对小麦的增产效果和土壤的培肥效果明显优于化肥 ,等同于市售复合肥。它能促进植株生长发育 ,提高小麦产量 ,对土壤速效养分的积累有明显的促进作用 ;污泥复合肥处理的小麦籽粒中重金属 Cu、Zn、Pb、Cd的含量均在国家食品卫生标准范围内。 Through pot experiment and field experiment, the effect of sludge compound fertilizer on wheat and its effect on wheat heavy metal absorption were discussed. The test results show that the effect of sludge compound fertilizer on wheat yield and soil fertility is obviously better than that of fertilizer, equivalent to the commercial compound fertilizer. It can promote the growth and development of plants and increase the yield of wheat, which can obviously promote the accumulation of available nutrients in soil. The contents of heavy metals Cu, Zn, Pb and Cd in wheat grains treated with sludge compound fertilizer are all within the national food hygiene standards .
