【摘要】 采用新鲜猪粪为材料,通过添加堆肥接种剂,研究了在堆肥发酵过程中磷组分的变化过程。结果表明,接种外源菌种能加速有机物的降解,使有机碳含量下降,这一浓缩效应提高了有机肥中全磷、有机磷、无机磷的含量;有机磷/无机磷前期变化大,后期逐步趋于稳定。发酵过程中C/P逐渐降低。更多还原

【Abstract】 Transition of P componuts in swine manure during composting course was studied by fresh swine manure. The results showed that the inoculants accelerated the decomposition of organic carbon,and increased the concentration of total P,inorganic P,and organic P in the final composting product.There was a great fluctuation in the ratio of inorganic P/organic P in early period of composting,and a less fluctuation in late period.C/N ratio decreased with an increase in the time of composting process.更多还原
