摘　　要：为筛选出适宜娃娃菜尾菜堆肥用混合发酵菌剂,促进尾菜肥料化利用,选用5种有机肥生产常用发酵菌剂,以娃娃菜尾菜和羊粪为原料,研究了不同发酵菌剂对堆肥温度、pH、含水率、C/N、全氮及有机质含量的影响。结果表明,采用亨坤有机肥发酵剂处理后,娃娃菜尾菜堆肥升温最快,处理后第4天达到56.1℃,第12天达到最高温度66.2℃,且高温天数持续了12 d。堆肥结束时,亨坤发酵菌剂处理的堆肥含水率最小(29.5%),降幅达54.7%;全氮含量最大(16.8 g/kg),增幅为98.4%;C/N最小(14.8),降幅为51.0%;有机质含量最低(320.0 g/kg),降幅为51.9%,降解率最高(51.8%),尾菜腐熟效果最好。综合考虑各项指标,堆肥结束时亨坤发酵菌剂处理的可塑性指数最大,发酵效果最佳,最适于娃娃菜尾菜与羊粪混合发酵制备有机肥。In order to screen suitable mixed fermentation agents for composting of mini Chinese cabbage tail vegetables and promote the fertilizer utilization of tail vegetables,5 kinds of commonly used fermentation agents for organic fertilizer production were selected,and mini Chinese cabbage tail vegetables and sheep manure were used as raw materials.The effects of different fermentation agents on composting temperature,pH,moisture content,C/N,total nitrogen and organic matter contents were studied.The results showed that after the treatment of Hengkun organic fertilizer fermentation agent,the composting temperature of mini Chinese cabbage tail vegetablesincreased the fastest,reaching 56.1℃on the fourth day after treatment,reaching the highest temperature of 66.2℃on the 12th day,and the days above the high temperature lasted for 12 days.At the end of composting,the moisture content of compost treated with Hengkun fermentation agent was the smallest(29.5%)with a decrease of 54.7%.The total nitrogen content was the largest(16.8 g/kg)with an increase of 98.4%.The C/N was the lowest(14.8)with a decrease of 51.0%.The content of organic matter was the lowest(320.0 g/kg),the degradation rate was the highest,and the rotten effect of tail vegetables was the best.Considering all the indexes,at the end of composting,the plasticity index of Hengkun fermentation agent treatment was the largest,and the fermentation effect was the best,which was most suitable for the preparation of organic fertilizer by fermentation of mini Chinese cabbages mixed with sheep manure.
