1稻草还田对晚稻稻田甲烷排放的影响显示文摘晚稻稻田的甲烷排放呈现前高后低特点 ,稻田甲烷的日排放速率与日均气温具有良好的正相关。稻草翻施使稻田甲烷排放量上升 5 1 .1 1 % ,而采用稻草表施的方法甲烷排放量仅增加 33.98%。水稻分蘖期是稻田甲烷排放的重要时期 ,其甲烷排放量占水稻全生育期排放总量的 65 .6% ,施用稻草进一步加大水稻分蘖期的甲烷排放比例。与稻草翻施相比 ,稻草表施的甲烷减排突出表现在水稻分蘖期及一天中 1 2∶0 0~ 1 6∶0 0的甲烷排放高峰时段。土壤 5cm处温度的昼夜周期性变化与稻田甲烷排放的昼夜周期性变化具有高度相关性。陈苇 卢婉芳 段彬伍 Wassmann R Lantin RS 2002土壤学报2002,39,2:49
2稻田土壤中甲烷产生率的实验研究显示文摘本实验旨在研究稻田土壤中甲烷产生率对稻田CH_4排放的影响.观测结果表明:土壤各深度的甲烷产生率有很大的变化范围(1—4639ng·h^(-1)·g^(-1)d.w.).主要的甲烷产生区域是7—17cm深的土壤层,其中以13cm深的土壤层上的生成速率最大.土壤中甲烷产生率与稻田CH_4排放率在水稻生长的某些阶段有较好的相关性,但它的季节变化却不能与排放的季节变化完全耦合.在水稻生长期,土壤中甲烷产生率随时间而增大,并在8月份水稻收割前达到最大,其日平均值在38—767 ng·h^(-1)·g^(-1)d.w.间变动.稻田土壤中甲烷产生率也存在日变化,一般在下午达到最大值,但却没有发现它与土壤温度有明显的相关关系.在不同施肥及水稻品种的稻田土壤中也观测到不同的甲烷产生率.在土壤中产生的甲烷最多只有28.8%被排放到大气中,而其余多于71.2%的则被氧化在土壤中.上官行健 王明星 R.

3猪粪与沼气渣对双季稻田甲烷排放的影响显示文摘随着环境温度的升高 ,稻田甲烷排放通量增加。早稻期间甲烷排放通量随着水稻生育期的增加而逐步加快 ,而晚稻甲烷排放主要集中在水稻生长的前中期 ,而且排放量很高。一天中甲烷排放具有很强的周期性 ,在 6:0 0~ 8:0 0时 ,甲烷排放通量进入谷底 ,1 4 :0 0时甲烷排放通量达到峰值。稻田甲烷排放通量与土壤 5cm处的温度及土壤水溶解甲烷含量具有较高的相关性。猪粪和沼气渣的施用分别提高稻田甲烷排放量 2 2 .1 4 %和 4 .4 0 %。在早稻期间 ,施用猪粪和沼气渣分别提高土壤水溶解甲烷含量 4 0 .3%和 1 1 .9% ,而晚稻期间仅分别提高 2 3.9%和 5.0 4 %。陈苇 卢婉芳 段彬伍 Wassmann R Lantin R S 2001生态学报2001,21,2:14
4Methane Production, Emission and Possible Control Measures in the Rice Agriculture显示文摘In the rice field methane is produced in the soil layer with depths of 2-25 cm. The vertical profile of methane production rate in the paddy soil during the water covering period differs from that in the paddy soil in dry phase. Only a small part, about 30%. of the produced methane is emitted to the atmosphere through rice plant, air bubbles, and molecular diffusion. Therefore, the methane emission rate from the rice field depends not only on the methane production rate in the soil, but also on the transport efficiency of the rice plant, air bubble formation that in turn depends on the production rate, and molecular diffusion.Field measurements show that methane emission rates from a particular rice field have very large diurnal, seasonal and interannual variations, which are related to soil characteristics, water regime, farming procedure, local climate, and rice growing activities. The relationship between the methane emission rate and the above mentioned factors is very complicated.

5稻田CH_4排放及控制技术的研究(英文)显示文摘为了探索北方稻田水管理、施肥和水稻品种对稻田甲烷排放的影响 ,于 1995年至 1998年应用全自动甲烷采样 -测定系统 ,测定了水稻田甲烷排放通量。实验探明 :北方稻田甲烷排放通量为 4~364mg/m2 .d,平均值为 82 mg/m2 .d;稻田甲烷的季节排放只有一个高峰 ,发生在水稻分蘖期 ,该期的甲烷排放量占年排放总量的 85 %以上 ,水稻生长中、后期的稻田甲烷非常有限。水管理对稻田甲烷的生成、排放有显著的影响 ,稻田采用间歇灌溉代替常规灌溉和淹灌 ,可减排稻田甲烷 4 6%~ 5 9% ;稻田施用有机肥 ,甲烷排放量则剧增。但在同等有机碳含量情况下 ,不同有机肥的产甲烷潜势存在明显差异 ,猪粪和稻草较高 ,堆肥和牛粪较低 ,稻田施用堆肥和牛粪 ,可比施用猪粪和稻草的稻田减排稻田甲烷 72 %~ 90 % ;试验中选用的水稻品种 ,以中作 93的甲烷排放效率为最低 ,其甲烷排放通量比杂交稻京优和高秆品种中花 94 - 10 17减少 5 0 %~ 5 5 %。实验揭示 ,水稻分蘖期是控制北方稻田甲烷排放的关键时期 。王增远 徐雨昌 李震 过益先 R Wassmann H U Neue R S Lantin L V Buendia 2001作物学报2001,27,6:5
