摘要: 对会同杉木幼林林下灌木层、草本层和地被物层中13种元素的含量、积累与分布特点进行研究的结果表明,植物体中营养元素含量,因植物种类不同和同种植物因器官不同而存在差异。主要营养元素积累量,在灌木层里的顺序为N>Ca>K>Mg>P,在草本层时而则为N>K>ca>Mg>P,而在死地被物层里又为ca>N>K>Mg>P。该项研究可为恢复和维护杉木林地力提供可靠依据。

Abstract: Contents,accumulation and distribution of 13 nutrient elements in shrub,herb and litter stratum of the young Chinese fir stand war studied in Huitong.The results showed that contents of nutrient elements varied among species and among organs of the same species.Regarding accumulation of major nutrient elements,the order waS N>Ca>K>Mg>P in shrub stratum,N>K>Ca>Mg>P in herb stratum,and Ca>N>K>Mg>P in Litter。
