马尾松、湿地松幼树生物量及养分积累
Biomass and Nutrient Accumulation of Pinus massoniana and Pinus elliottii Saplings
摘要
Abstract
The biomass and nutrient accumulation of pinus massoniana and pinus elliottii saplings with the same forest age under simi-lar habitat were studied in Yangyuan Village,Zhenghe County,Fujian Province,the results showed that the biomass of stem,bark, leaf,main root and lateral root were pinus elliottii>pinus massoniana,the stand biomass of pinus elliottii forest was higher than pinus massoniana;the concentration of N、P、Ca、Fe was pinus massonian>pinus elliottii,the concentration of nutrient elements in leaves was higher than other different parts,followed by lateral root,branch and skin;the nutrient accumulation of N,P and Ca was pinus massoniana>pinus elliottii,the nutrient accumulation of C、K、Mg、Fe was pinus elliottii>pinus massoniana,nutrient use efficiency calculation showed that pinus elliottii young forest use efficiency of various nutrient elements was higher than that of pinus massoni-ana,with the same dry matter production,the nutrient took away from the soil in pinus elliottii forest was less than that in pinus mas-soniana forest.关键词
