模拟酸雨对福州平原水稻田土壤碳、氮、磷含量及其生态化学计量学特征影响

Shuitu Baochi Xuebao, 2019
为阐明酸雨对水稻田土壤碳（TC）、氮（TN）、磷（TP）含量及其生态化学计量学特征影响，以福州平原水稻田为研究对象，在早稻和晚稻生长期中，设置对照（CK）、模拟酸雨（pH为2.5，3.5，4.5）处理，对酸雨影响下福州平原水稻田土壤TC、TN和TP含量进行了测定与分析。结果表明：综合早稻和晚稻生长期来看，酸雨处理下土壤TC、TN和TP含量均值均大于CK组 ...

常绿阔叶林土壤团聚体磷组分和有机碳化学分子结构对氮磷添加的响应

Shuitu Baochi Xuebao
目的为揭示亚热带常绿阔叶林氮磷（N、P）添加对土壤团聚体碳的影响及其内在机制，掌握亚热带常绿阔叶林中土壤有机碳的稳定性及生态系统碳循环规律。方法在常绿阔叶林布设长达6 a的N、P添加试验平台［对照，100 kg/（hm2·a）（以N计），50 kg/（hm2·a）（以P计），100 kg/（hm2·a）（以N计）+50 kg/（hm2·a）（以P计）］，分析土壤团聚体粒径分级、磷组分和有机碳化学分子结构组成，探究不同粒径土壤有机碳对N沉降和P添加的响应。结果N添加处理显著提高大团聚体（>2 mm ...
