摘要
研究了三倍体毛白杨S8[(P.tomentosa×P.bolleana)×P.tomentosa]叶片营养元素含量季节性变化规律及元素间的相互关系。结果表明:叶片N、P、K、Ca、Mg、Fe、Mn、Cu、Zn、Cr、As、N i、Co、Ba、B和Cd含量随季节变化而发生显著变化;不同离子间的相互作用也不尽相同。
The author studied the content and relation of nutrition element of Populus tomentosa S8 [ ( P. tomentosa × P. bolleana) ×P. tomentosa]. The results showed that N, P, K, Ca, Mg, Fe, Mn, Cu, Zn, Cr, As, Ni, Co, Ba, B, and Cd contents of leaves changed evidently with the seasonal change. There are different relationships between different nutrition elements.
