摘　　要：利用玉米秸秆屑、稻草秸秆屑和牛粪为原料进行序批式好氧堆肥，对堆肥处理的过程参数的变化规律进行了研究。结果表明：2个处理的物料温度在50～54℃维持7d以上，最终反应产物的无害化程度较高；最终剩余产物的氮、磷、钾相对含量都有所升高，达到了农用控制标准；处理过程中氮素均呈增加趋势；由于在好氧反应阶段存在不同程度的氮损失，因此在反应的后期阶段要注意采取保氮措施。Maize corn straw stem, rice straw stem and cow dung were used as raw materials for aerobic composting sequencing batch type to explore composting treatment process parameter change law. The results showed that the two material handling between 50~54 ~C temperature and maintaining more than 7 days, the final reaction harmless products were of high degree, and final product surplus of nitrogen, phosphorus and potassium was increased, the relative contents achieved the agricultural control standard. During the treatment process, nitrogen was in- creased. Due to different levels of nitrogen losses in the aerobic reaction phase, the appropriate measures shoule be adopted to protect nitro- gen in the late stages of reaction.
