牛粪接种复合发酵剂堆肥对腐殖酸变化特征的影响

he experiment was inoculated complex microbial agent to cattle manure compost at lower 0℃, discussing effects of complex microbial agent on changes of humic carbon characteristics during cattle manure compost. The results showed that the content of total humic carbon and fulvic acid (FA) decreased during composting, but the content of humic acid (HA) decreased at the initial stage of composting, then increased gradually in the period of cattle manure compost. The ratio of the total humic carbon to total carbon increased, so was the HA/FA. The degree of composting humification increased during cattle manure inoculated complex microbial agent.
