模拟氮沉降对三种南亚热带树苗生长和光合作用的影响 %A LI De-Jun %A
李德军 %J 生态学报 %D 2004 %I %X To evaluate the responses of subtropical forest trees in China to elevated nitrogen (N) deposition, we sprayed dissolved NH_4NO_3 on seedlings of Schima superba, Castanopsis chinensis and Cryptocarya concinna twice every month. The simulated elevated N depositions were equivalent to 0 (A), 5 (B), 10 (C), 15 (D) and 30 (E) g N/(m~2·a) and began in January, 2003. The results indicated that stem base diameter, height and branch number of seedlings for these three species increased significantly with N loads, w... %K nitrogen deposition %K subtropics %K tree seedlings %K growth %K photosynthesis
