• 摘要：利用强制通风密闭箱式堆肥系统处理死鸡,分别在冬季和春季进行两期堆肥处理死鸡试验,冬季试验设置0.035、0.025和0.015 m³·m^-3·min^-1 3个通风量, 春季试验设置0.045、0.035和0.025 m³·m^-3·min^-1 3个通风量,研究不同通风条件下堆肥处理死鸡过程中死鸡的分解效果.结果表明,冬季和春季堆肥试验过程中,各通风处理条件下死鸡的分解率均在85%以上,冬季堆肥试验通风量为0.035 m³·m^-3·min^-1时, 处理效果最好,死鸡分解率为90.5%;春季堆肥试验通风量为0.045 m³·m^-3·min^-1时,处理效果最好,死鸡分解率为90.2%.

• Abstract：Dead hens were treated using closed composting bins with forced ventilation system. To explore effect of ventilation rates on dead hens decomposition, composting experiments with three ventilation rates were implemented in winter and spring. The ventilation rates applied were 0.035, 0.025 and 0.015 m³·m^-3·min^-1 in winter experiments, and 0.045, 0.035 and 0.025 m³·m^-3·min^-1 for spring experiments. It was found that the decomposition rates of dead hens were more than 85% under different ventilation rates both in winter and spring. The suitable ventilation rates for dead hens composting treatment were 0.035 m³·m^-3·min^-1 with decomposition rate of 90.5% in winter, and 0.045 m³·m^-3·min^-1 with decomposition rate of 90.2% in spring, respectively.

• Key words：ventilation rate  compost  dead hens  decomposition rate
