摘要:

水曲柳(Fraxinus mandshurica)是我国东北林区重要的工业用材树种,在东北林区广泛种植,因而其培育近来日益得到高度重视。在水曲柳的种植区域内,尽管林地内凋落物丰富,但该地区气温低,冬季长,氮素矿化速度低,氮素供给显得不足。本研究采用沙培的方式,在为幼苗提供完

Abstract:

Fraxinus mandshurica, native to northeastern China, is an important timber tree. The tree often suffers from nitrogen (N) deficiency because long winter results in slow decomposition rate of litter. In the present study, effects of different concentration
