| 摘 要： | 对黑土水稻田一个生长季中土壤微生物生物量C、土壤呼吸和甲烷排放通量进行了监测。结果表明，在水稻生长初期，长效尿素能显著抑制微生物生物量C和土壤呼吸(P<0．05)，间歇灌溉措施对二者几乎没有影响，间歇灌溉能减少稻田甲烷的排放，平均排放量比对照减少了32．5％，长效尿素的施用稻田使甲烷的排放略有增加，施用长效尿素的处理，微生物生物量C与甲烷排放量之间呈显著正相关关系。

| Abstract: | The measurements of soil microbial biomass C,respiration rate and CH 4 emissions during one rice growth period in black earth rice fields showed that the soil microbial biomass C and respiration rate were depressed significantly by the application of slow releasing urea at the early stage of rice growth period (P<0.05),but almost not affected by intermittent irrigation.The CH 4 emission was decreased by 32.5% in the intermittent irrigation treatments,but not significantly affected by the application of slow releasing urea,compared to the control.It was significantly related to soil microbial biomass C in slow releasing urea treatments. |
