Results show that microbial biomass carbon and microbial biomass nitrogen in fertilized soil peak in the first several days, and then decline. Incubating both sweet maize straw and white clover have the highest yield, maxima of 529.57 mgkg^(-1) and 75.50 mgkg^(-1) respectively. They also release respired CO2 the most among all treated soils. The best mineral nitrogen release is in white clover incubating, with a maximum of 29.81 mgkg^(-1) under a 26-day culture, and then keeping 1.60 times the control and reaching 2.48 times at 80-day culture. Sweet maize incubating has the least mineral nitrogen release. It is 13%~53% of the control under a 26-day culture, with a maximum of 7.51 mg kg^(-1). Soil nitrogen mineralization is insignificant under sweet maize incubating with urea in short-term.

研究发现，各施肥处理的土壤微生物量碳、微生物量氮均在培养前期出现峰值，后期平稳降低；甜玉米桔秆和白三叶草绿肥同时还田的土壤微生物量碳、微生物量氮在各培养时期均最大，峰值分别达529.57 mgkg^(-1)，和75.50 mgkg^(-1)，土壤呼吸产生的CO2最多；白三叶草绿肥单独还田有利于土壤无机氮的释放，培养第26d无机氮达到最大值，为29.81 mgkg^(-1)，之后一直在对照处理的1.60倍以上，第80d达到2.48倍；甜玉米秸秆单独还田不利于土壤无机氮的释放，培养的第26d至结束，甜玉米秸秆处理的无机氮为对照的13%~53%，最大为751 mgkg^(-1)；甜玉米秸秆配施尿素，短期内不利于土壤无机氮矿化。
