Impacts of Land Use, Fertilizer and Manure Application on the Stream Nutrient Loadings in the Salmon River Watershed, South-Central British Columbia, Canada
Model Landuse Nitrogen Phosphorus Fertilizer Manure
2013/3/11
Manure and fertilizer applications can increase soil productivity and land economic values, but the controversial result can be a decline of water quality due to the increased nutrient exports from so...
Biofiltration of Nitrous Oxide Using Cow-Manure Based Compost as Medium Filter
Biofilter Compost Cow-Manure Nitrous Oxide Removal Efficiency
2013/3/11
Nitrous oxide (N2O) gas is a fourth contributor in the greenhouse effect after CO2, CH4, and water vapor. Although its concentration is relatively low, but very difficult to be decomposed in the atmos...
应用Manure-DNDC模型模拟畜禽养殖氮素污染
氮 粪便 模型 Manure-DNDC 农业面源污染
2012/8/14
畜禽养殖是重要的农业面源氮素污染源头，大量的畜禽粪便施入农田后，会加大农田氮素径流和淋溶损失强度。畜禽养殖废弃物氮素污染过程复杂，涉及到动物自身营养循环以及废弃物通过不同途径进入环境的过程，目前大多通过排放系数法估算畜禽养殖过程产生的氮素污染负荷。该文选用最新版Manure-DNDC模型，以山东小清河流域为例，模拟畜禽养殖及废弃物处理的生物地球化学过程，分析氮素在动物、畜禽粪便、农田之间的迁移转化...
鸡粪工厂化堆肥过程中有机质含量预测模型（Prediction Model for Organic Matter Content in Chicken Manure during Plant-field Composting）
鸡粪 工厂化堆肥 有机质
2010/1/28
以148份肉鸡粪和菊花渣工厂化高温堆肥过程样品为研究对象，分别探讨了基于基本理化指标和近红外光谱预测鸡粪堆肥过程中有机质含量的可行性。根据样品中干物质含量、pH值和电导率3种理化指标与有机质含量的相关关系建立了基于理化指标预测有机质含量的一元和二元线性回归模型。结果表明，利用干物质含量预测有机质含量简便、易行且最具实际应用价值（R2=0.81, P<0.001）。采用多元线性回归、主成分回归和偏最...
牛粪、鸡粪和稻秆混合的沼气发酵特性与工艺优化（Fermentation and Process Optimization of Mixed Cow Dung,Chicken Manure and Rice Straw for Biogas Production）
沼气发酵 牛粪 鸡粪 稻秆 温度 配比
2010/4/1
采用可控恒温厌氧发酵装置，选用牛粪、鸡粪、稻秆3种原料，按干物质比例0∶2∶1、0.4∶1.6∶1、0.8∶1.2∶1、1.2∶0.8∶1、1.6∶0.4∶1、2∶0∶1混合，研究了各配比在15℃、20℃、25℃、30℃下的厌氧发酵情况。结果表明：随温度升高，各配比产气速率和累积产气量均增大，15℃下发酵周期最长，其他温度对发酵周期影响无显著差异；不同配比下，累积产气量均呈先增大后减小的趋势，牛粪...
