Abstract

Abstract: The accumulation,distribution and bioligical cycling of 11 nutrient elements in the three plantation ecosystems of 12-year-old Eucommia,Chinese Corktree,Twolobed Official Magnolia are studied.The results show that among the various organs of above ground,the nutrient elements contents are different,that the changing rules of the nutrient element contents in plant and soil system are identical,that the orders of the average rates of nutrient elements in the biollogical cycling of these three medicine plantations are,Twolobed Officinal Magnolia>Eucommia>Chinese Corktree,and that the utilization efficiency of the nutrient elements in stand systems is in order of Eucommia>Chinese Corktree>Twolobed Officinal Magnolia.

Key words: Eucommia, Chinese Corktree, Twolobed Officinal Magnolia, Nutrient element, Biological cycling
