摘    要: 以小桐子油枯为基本原料进行高温堆肥试验,研究了不同比例玫瑰废弃物与小桐子油枯(1∶1,1∶2,1∶5)混合堆肥体系中温度、总氮(TN)、水溶性NH+4-N,水溶性NO-3-N和游离氨基酸的动态变化规律。结果表明,纯小桐子油枯(对照)的NH+4-N, NO-3-N,游离氨基酸在堆肥进程中的浓度最高,以配比1∶5,12,1∶1的顺序浓度依次增加。适当加入玫瑰废弃物(1∶5),能使TN损失最少,也能增加一定的NH+4-N,NO-3-N,游离氨基酸浓度。

关 键 词:小桐子油枯  玫瑰废弃物  堆肥  氮素变化

Abstract:The dynamic changes of total nitrogen(TN), soluble NH+4-N, soluble NO-3-N, free amino acid in composting by different ratios of rose residue and Jatropha curcas oil dry(1∶1,1∶2,1∶5), and control test of pure J. curcas oil dry were studied. The result showed that, control test of J. curcas oil dry was propitious to enhance the concentration of soluble NH+4-N, soluble NO-3-N, free amino acid in composting. The concentration were increased in ratios of 1∶5,1∶2,1∶1 gradually. Adding rose residuce to J. curcas oil dry compost(1∶5) also increased the concentration of soluble NH+4-N, soluble NO-3-N, free amino acid and reduced the total nitrogen(TN) loss.
Keywords:Jatropha curcas oil dry  rose residue  compost  dynamic change of nitrogen
