| 摘 要： | 目的]探讨有机物料对黄壤主要理化性质及外源铜有效性的影响。方法]采用动态培养法研究4种有机物料对黄壤主要理化性质及外源铜有效性的影响。结果]猪粪和玉米秸秆处理使黄壤pH值升高,但随着培养时间的延长这种影响减弱。泥炭和风化煤处理对土壤pH值影响不大。各有机物料的加入均使土壤活性铁和络合铁含量显著增高,且玉米秸秆和猪粪处理对土壤活性铁含量的影响更为突出;各有机物料的加入对活性铝和络合铝的影响不显著,但风化煤处理与泥炭和猪粪处理间的活性铝含量变化存在显著差异。有机物料的加入降低了土壤中外源铜的有效性,并随时间的增长降低得更明显,且泥炭和风化煤的影响强于猪粪和玉米秸秆。结论]该试验为有机物料对土壤铜含量影响机制的研究作出一定补充。 |
