动物园内的动物粪便和水杉落叶为原料，分别采用时间-温度联合控制（Ⅰ号堆体）、时间控制（Ⅱ号堆体）的强制通风控制方式进行堆肥试验，考察了2种强制通风控制方式对动物粪便堆肥过程中氮、磷元素变化的影响．研究结果表明，经过51d的堆肥化以后，Ⅰ、Ⅱ号堆体的NU；-N平均含量分别从0．95g-kg-1和0．78g·kg^-1下降到0．36g·kg^-1和0．62g·kg^-1，NO3^--N平均含量分别从152mg·kg^-1和120mg·kg^-1增加到351mg·kg^-1和243mg·kg^-1于“浓缩效应”，堆肥过程中TN、TP、速效磷的含量均有所增加，Ⅰ、Ⅱ号堆体的TN平均含量分别从16．05g·kg^-1和15．71g·kg^-1增加到19．70g·kg^-1和21．41g·kg^-1，TP平均含量分别从8．17g·kg。和8．23g·kg^-1增加到9．38g·kg^-1和9．62g·kg^-1，速效磷平均含量分别从1．83g·kg^-1和1．99g·kg^-1增加到2．81g·kg^-1和3．57g·kg^-1．统计分析结果表明，这2种强制通风控制方式对堆肥过程中速效磷含量变化有着显著的影响（P=0．002），但对其它指标（C／N比、NU4^＋-N、TN、NO3^--N、TP）含量变化的影响却不显著（P〉0．05）．

Abstract： Experiments were carried out to investigate the impact on nitrogen and phosphorus in animal manure composting with two kinds of aeration control modes, time - temperature control for Pile Ⅰ and time control for Pile Ⅱ. The results showed that after 51 days composting, the NH4^＋ -N concentrations in Pile Ⅰ and Pile Ⅱ decreased to 0.36 g· kg^-1 and 0.62 g· kg^-1 from 0.95 g· kg^ - 1 and 0.78 g· kg^-1, respectively, and the NO3^- -N concentrations in Pile Ⅰ and Pile Ⅱ increased to 351 mg· kg^-1 and 243 mg· kg^-1 from 152 mg· kg^-1 and 120 mg· kg^-1 , respectively. The concentrations of TN, TP and available phosphorus increased due to concentration effect. The TN concentrations in Pile Ⅰ and Pile Ⅱ increased to 19.70g· kg^-1 and 21.41 g· kg^-1 from 16.05 g· kg^-1 and 15.71g· kg^-1, respectively, and the TP concentrations in Pile Ⅰ and Pile Ⅱincreased to 9.38 g· kg^-1 and 9.62 g· kg^-1 from 8.17 g· kg^-1 and 8.23 g· kg^-1, respectively, and the available phosphorus concentrations in Pile Ⅰ and Pile Ⅱincreased to 2.81 g· kg^-1 and 3.57g· kg^-1 from 1.83 g· kg^-1 and 1.99 g· kg^-1 respectively. Statistics results showed that the aeration control mode had significant effect on changes of the available phosphorus concentration （p = 0. 002）, but had little significant effect on these indexes, including C/N ratio, NH4^＋ -N, TN, NO3^- -N and TP （p 〉0.05）.
