为研究猪粪堆肥中铜锌与腐殖质组分的结合竞争,以猪粪和秸秆为堆腐原料,进行了为期36 d的好氧堆肥实验,研究猪粪堆肥过程中腐殖质组分(胡敏酸和富里酸)、胡敏酸结合态铜锌、富里酸结合态铜锌含量的变化。结果表明,堆肥结束后,腐殖化程度提高,胡敏酸碳含量增加394.4%,富里酸碳含量降低64.9%,腐殖化指数从0.24增加到3.33;随着堆肥的进行,胡敏酸结合态铜锌含量分别增加394.3%和56%,而富里酸结合态铜锌含量分别下降17.5%和28.4%;相关分析表明,胡敏酸结合态铜、富里酸结合态锌与胡敏酸、富里酸碳含量及腐殖化指数均成显著相关(P

Aerobic composting experiment which pig manure and rice straw were used as the basic raw materials was conducted to research the competitive binding of copper and zinc with humic acid (HA) and fulvic acid (FA). The contents of HA, FA, humic acid-Cu (HA-Cu), humic acid-Zn (HA-Zn), fulvic acid-Cu (FA-Cu) and fulvic acid-Zn (FA-Zn) during 36 days composting were investigated. Results show that the humification increased, in which the carbon content of HA increased by 394.4% and the carbon content of FA decresed by 64.9%, the humification index (HI) increased from 0.24 to 3.33. The concentration o...
