摘  要：
为探讨在铅污染土壤中加入蜂窝煤灰渣对土壤磷形态的影响及其与铅有效性的关系。设置加铅(500 mg/kg)和不加铅土壤,并施用水溶性磷肥[n(P)∶n(Pb)=4]及灰渣(20 g/kg),种植黑麦草,植物收获后测定土壤Olsen-P、Ca2-P和Ca8-P含量。结果表明,加入灰渣可增加土壤Olsen-P和Ca8-P含量;未施用磷肥条件下,加入灰渣可增加土壤Ca2-P含量,施用磷肥后再加入灰渣,Ca2-P含量显著降低(P<0.05);Ca2-P、Ca2-P+Ca8-P和Olsen-P含量均与土壤DTPA-Pb含量显著负相关(P<0.05),以Ca2-P与DTPA-Pb的相关性最强(P<0.01)。可见,铅污染土壤中施用蜂窝煤灰渣可增加土壤磷有效性,稳定Ca2-P水平,降低土壤铅有效性。

摘  要：
The experiment was conducted to investigate the effect of applying honeycomb briquette combustion residue(HBCR) on the speciation of soil phosphorous(P) and lead(Pb) availability.Pb-spiked(500 mg/kg Pb) or non-spiked soil was amended with water soluble phosphorus(n(P)∶n(Pb)=4) and HBCR(20 g/kg dry soil),ryegrass(Lolium perenne L.) was planted.After harvest,soil was analyzed for Olsen-P,Ca2-P and Ca8-P.Olsen-P and Ca8-P contents increased in all treatments after HBCR application.HBCR application in treatments without P application increased Ca2-P contents,however,in treatments with P application,HBCR application resulted in lower Ca2-P contents(P<0.05).Soil contents of Ca2-P,Ca2-P+Ca8-P and Olsen-P all correlated with DTPA-Pb contents negatively(P<0.05),while the correlation of Ca2-P was the most robust(P<0.01).The results suggest that the HBCR can be amended to Pb-polluted soil to increase P availability,moderate Ca2-P level and to reduce Pb availability.
