| 摘 要： | 研究了在有机肥堆制过程中加入一定量的化肥后腐殖酸总量、游离腐殖酸、胡敏酸、富里酸养分形态发生的转化.结果表明,由于微生物的作用,有机质含量快速下降,变温条件下下降的速率快于恒温条件;腐殖酸总量无明显增加,游离腐殖酸和胡敏酸表现出明显的增加趋势,变温条件下增加的速率快于恒温条件;富里酸呈现明显的下降趋势,胡富比增大.

| Abstract: | The changes of the total amount of humic acid,the free humic acid,the humic acid and the fulvic acid were studied by adding inorganic fertilizer during composting.The results showed that because of the function of the microorganism,the content of organic matter decreased quickly,and the decreasing velocity in the change temperature condition was quicker than that in the constant temperature condition.The total amount of the humic acid did not increase obviously.The free humic acid and humic acid expressed an obvious increasing trend,and the increasing velocity in the change temperature condition was quicker than that in the constant temperature condition.The fulvic acid decreased obviously.And the ratio of H/F acid increased. |
