To sum up,the long-term use of manure has significant effect on the emission of CO_2 from mineralization of organic Carbon;the use of chemic fertilization significantly increases the production of N_2O,yet the same amount of organic-N have smaller effect on it.
综上分析,长期施用有机肥显著影响红壤有机碳矿化释放的CO_2量;施用化肥显著提高红壤N_2O释放量,而施用等量有机态氮对其的影响较小。
