摘　　要：分别添加体积比为0、10%、20%、30%、40%和50%的稻秆作为调理剂对泔脚进行蚯蚓堆肥处理,然后以堆肥产物中的总氮(TN)含量、总磷(TP)含量、总钾(TK)含量、过氧化氢酶(CAT)活性4个指标和堆肥产物中种植小白菜1个月后的株高、叶面积指数、根长、干重及鲜重5个指标建立起评价指标体系,采用因子分析法结合灰色关联模型对添加不同比例稻秆调理剂的泔脚堆肥产物的还田效果进行评价。结果表明,当稻秆加入比例为0~30%时,堆肥产物的还田效果一直处于Ⅲ、Ⅳ级之间并无明显变化;当稻秆加入比例增至40%时,堆肥产物的还田效果提高到Ⅰ级;而继续增加至50%时,综合还田效果又降低为Ⅱ级。说明蚯蚓堆肥技术处理泔脚时加入40%的稻秆调理剂其堆肥产物还田效果最佳。Byproduct from hogwash was treated by vermicomposting with different volume proportion（0,10%,20%,30%,40%,50%） of rice straws as amendments firstly,and then the evaluation index system was established with Total N（TN） content,total P（TP） content,total K（TK） content,catalase（CAT） activity,plant height,leaf area index,root length,dry weight and fresh weight of plant as evaluation indexes. Factor analysis combined with gray correlation model was employed to evaluate the fertilizer effect of byproduct from hogwash. The results indicated that the fertilizer effect of byproduct from hogwash had been fluctuating between level Ⅲ or level Ⅳ without obviously change when rice straws were added to 0-30%,while fertilizer effect was increased to levelⅠwith 40% rice straws content. However,the fertilizer effect was decreased to levelⅡ when the addition of rice straws continued to increase to 50%. The results concluded that when 40% of rice straws as amendments,fertilizer effect of byproduct from hogwash reached the best performance.
