【摘要】 为了研究磷矿粉添加量对餐厨废弃物堆肥腐殖酸演化的影响，一共设置了4个处理，整个堆肥周期持续30 d。结果表明：(1)添加10%(质量分数，下同)、15%的磷矿粉可促进堆肥的腐殖化。(2)添加10%的磷矿粉有利于胡敏酸(HA)中复杂组分(C3、C4)的形成。(3)磷矿粉添加有利于促进高温双岐菌(Thermobifida)、芽孢杆菌(Bacillus)、慢生芽胞杆菌(Lentibacillus)和薄壁芽孢杆菌(Gracilibacillus)的生长，抑制乳酸杆菌(Lactobacillus)的生长，因此有利于腐殖酸的形成。更多还原

【Abstract】 This article aimed to study the effect of phosphate rock powder addition on the humic acid evolution of food waste composting. A total of 4 treatments were set up, and the entire composting cycle lasted for 30 days. The results showed that:(1) adding 10% and 15%(mass fraction) phosphate rock powder could promote the humification of composting.(2) Adding 10% phosphate rock powder was beneficial for the formation of complex components(C3 and C4) in humin.(3) The addition of phosphate rock powder was beneficial for promoting the growth of microorganisms Thermobifida,Bacillus,Lentibacillus and Gracilibacillus,inhibiting the growth of Lactobacillus,and therefore promoting the formation of humic acid.更多还原
