研究了甘蔗叶与牛粪混合物不同堆肥方式对氮素转化规律的影响。将甘蔗叶与新鲜的牛粪以1∶3的质量比充分混合，在同样的外界条件下，采用密闭容器强制通风法和翻堆法两种好氧发酵法进行堆肥。结果表明，翻堆堆肥相比于通风堆肥：温度高2.1～5.2℃，有机质降解率高28.25％，最终含水率高8.08％，最终 pH 值高0.12。这些因素的不同导致通风堆肥的硝态氮高出翻堆堆肥23～165 mg· kg-1；氨氮含量前13 d 通风堆肥高出翻堆堆肥48～1017 mg·kg-1，后期翻堆堆肥高出1～42 mg·kg-1；亚硝态氮含量前9 d 翻堆堆肥高出通风堆肥285～425 mg· kg-1，后期通风堆肥高出41～118 mg·kg-1。表明，两种不同堆肥方式中氮素的转化规律不同，翻堆堆肥更有利于促进氮素转化。

The effect of different composting methods of sugarcane leaves and cow manure mixture on nitro-gen transformation was evaluated with the mass ratio of sugarcane leaves and cow manure 1∶3.The study was conducted with aeration method and turning method under the same external conditions.Compared to aeration method,the temperature enhanced by 2.1~5.2 ℃,the degradation rate of the organic matter enhanced by 28.25%,the final moisture content increased by 8.08%,the final pH value raised by 0.12 in turning method. The concentration of nitrate nitrogen was 23~165 mg·kg-1 lower in turning method.The concentration of am-monia nitrogen in the first 13 d was 48~1 017 mg·kg-1 lower in the turning method,and 1~42 mg·kg-1 higher at last in the turning method.The concentration of nitrite nitrogen in the first 13 d was 285~425 mg· kg-1 higher in the turning method,and 41~118 mg·kg-1 lower at last in the turning method.The results showed that the transformation of nitrogen was different in different composting systems,and the turning meth-od was more effective in nitrogen transformation.
