Distribution and accumulation pattern of nutrient element in Pinus sylvestriformis plantation ecosystem

Abstract

Abstract: The study shows that in tree layer,the nutrient content in various organs is in the order of needle>branch>root>bark>trunk,that in assimilated organ is in the order of N>K>Ca>P>Mg,and that in absorption organ is in the order of Ca>N>K>P>Mg In plantation ecosystem,the nutrient content is in the order of Soil>litter>herb layer>shrub layer>tree layer.The nutrient storage and its accumulation rate in tree layer are occupied by 88.79 % and 76.43% respectively.The absorption of N and P by plants in Pinus sylvestriformis ecosystem is more intensive.

Key words: Pinus sylvestriformis, Plantation ecosystem, Nutrient element, red soil dryland, grey relational analysis, multiple cropping pattern
