摘　　要：为探究硫酸亚铁对鸡粪堆肥高温期真菌群落,以及其堆肥产品对植物生长的影响,以鸡粪和稻草为原料,以不添加任何外源添加剂的堆体作为对照组,设置硫酸亚铁添加比例分别为1%、2%的处理组,研究真菌群落组成与结构的变化,以及各堆肥产品施用后小白菜生长状况和营养品质的变化。结果表明:添加硫酸亚铁影响了鸡粪堆肥高温期的真菌群落结构,提高了真菌群落的多样性,富集了多数与木质纤维素降解相关的优势真菌,有利于堆肥中难分解有机物的高效降解,促进了堆肥的腐殖化进程。添加硫酸亚铁堆肥产品处理组小白菜的株高、叶绿素含量、可溶性蛋白含量、可溶性糖含量均较普通堆肥产品处理组显著(P<0.05)提高,并以添加2%硫酸亚铁的堆肥产品的效果更为突出。In order to examine the impact of ferrous sulfate on the fungal community during the thermophilic phase of chicken manure composting,as well as the effects of the compost products on plant growth,chicken manure and rice straw were used as raw materials,with the control group being the heap without any exogenous additives and the treatment groups being the heap with 1%or 2%ferrous sulfate addition.The changes in the composition and structure of the fungal community,as well as the growth condition of pakchoi and its nutrient quality were monitored.It was shown that adding ferrous sulfate to chicken manure composting affected the structure of the fungal community during the thermophilic phase,enhanced the diversity of the fungal community,enriched most of the dominant fungi related to lignocellulose degradation,which was conducive to the efficient degradation of difficult-to-decompose organic matter in composting,and facilitated the composting humification process.Plant height,chlorophyll content,soluble protein content and soluble sugar content were significantly(P<0.05)higher in the treatment groups compared to the control group.The effect of compost product with addition of 2%ferrous sulfate was more pronounced.
