摘要
在我国北亚热带高海拔地区应用分解网袋法,研究了红三叶叶片凋落物在分解过程中营养元素的释放特征。结果表明,在分解过程中,各类营养元素的含量和残留率的动态特征均有明显不同。根据这些特征,将其释放模式分为4类,即物理因子主导型、生物因子主导型、生物和物理双重因子主导型和化学因子主导型。
Release characteristics of nutrient elements in leaf litter decomposition of Trifolium pratense was examined using litter net bag method at high elevation area of north subtropical zone of China The result shows that the dynamic characteristics of content and remaining rate in nutrient elements of each type are obviously different during the decomposition process According to the characteristics, release patterns of nutrient elements of leaf litter in T pratense are divided into 4 types: release type by physical factors; by biological factors; by double physical and biological factors; by chemical factors
