摘要(Abstract):
以亚热带地区杉木人工幼林为研究对象,利用土壤埋设电缆增温实验平台,设置增温(5±0. 5)℃和对照两个处理,探讨杉木幼林成熟叶氮、磷含量及其不同形态组分对增温的响应.经过为时1. 5 a土壤增温,对成熟叶中氮、磷及其各组分含量分别进行测定.研究结果表明:增温处理未改变成熟叶总氮及其各形态组分含量,却显著降低了成熟叶中无机磷、糖磷、不溶磷组分含量;相关分析表明成熟叶总磷含量与无机磷组分含量极显著正相关(P=0. 000),与不溶磷组分含量显著正相关(P <0. 05).增温引起成熟叶总磷显著下降及总氮/总磷的显著增加,主要是由于成熟叶中无机磷和不溶磷组分含量显著下降导致.
