Accumulation and distribution characteristics of nutrient elements on Manglietia glauce plantation
摘要
Abstract
The concentration, accumulation, annual net accumulation and distribution of nine nutrient elements, such as N, P,K,Ca,Mg,Fe,Mn,Zn and Cu, were studied in 46-year-old Manglietia glauca stand in the city of Nanning, Guangxi, China. The results showed that the concentration of these nine nutrient elements in different components of Manglietia glauca stand was in the order of leaf > bark > root > branch > stem. The content of N and K were the highest in root, P and Mg were the highest in leaves, and Ca was the highest in bark. The content of Mn was the highest, Fe and Zn was in the middle, and Cu was the lowest. The total nutrient accumulations in 46-year-old M. glauca stand was 1 948. 78 kg/hm2,within the accumulations of the tree, herb, bush and liner were 1 715.22 kg/hm1, 74. 33 kg/hm2, 83. 19 kg/hm2 and 76.04 kg/ hm2, accounted for 88.02% ,3.81% ,4. 26% and 3.90% , respectively. The annual net accumulation of nutrient elements in Manglietia glauca plantation was 37. 32 kg/( hm2 · a). The order of annual net accumulation of nutrient elements in differeni parts of trees was stem > root > bark > leaf > branch.关键词
