| Abstract: | Based on located observation and chemical analysis in the Casuarina equisetifolia plantation of 15 age, the biological cycling of microelements in the ecosystem was studied. The results showed that the total amount of microelements accumulated in the stand was 23. 022kg/hm2, the annual retion were respectively 2. 071kg/hm2 and 2. 986kg/hm2, and the annual absorption was 5. 057kg/hm2. The return absorption ratio was 59. 0%, and the order of cycling ratio in the microelements was Fe>Mn>Zn>B>Mo>Cu. |
