摘　　要：为探究稻秆调理剂对泔脚蚯蚓堆肥的影响,分别设置A、B、C、D、E、F 6种蚯蚓堆肥处理进行试验,并对堆肥过程中各组分变化进行研究。结果表明,在泔脚蚯蚓堆肥中加入稻秆调理剂可降低堆肥的全盐含量,混合物腐熟后不会对植物产生盐分毒害作用,且堆肥原料全部为泔脚时可显著提高堆肥TP;泔脚与稻秆体积比为9∶1时可显著降低堆肥毒性,但TK易损失;泔脚与稻秆体积比为8∶2时可显著促进堆肥中氮素的增长;泔脚与稻秆体积比为7∶3时微生物和蚯蚓对有机质的降解效果最佳;泔脚与稻秆体积比为5∶5时TP易流失。综合考虑,泔脚与稻秆体积比为8∶2或7∶3时蚯蚓堆肥效果较佳。Six experiments were carried out to study the effects of rice straws on vermicomposting of hogwash waste. Each ex- periment contained hogwash waste mixed with different volume ratio of rice straws. Several indexes were determined on the process of vermicomposting. Compared with the pure hogwash waste, rice straws as additive could effectively dilute the salini- ty during vermicomposting. When decomposition, the composts did not produce salt toxic action. During vermicomposting, the treatment mixed with 0% of rice straws effectively increased TP. The treatment mixed with 10% of rice straws effectively de- creased the phytotoxicity of composting, but lost TK easily; The treatment mixed with 20% of rice straws effectively increased TN. The treatment mixed with 30% of rice straws decreased TOC best. The treatment mixed with 50% of rice straws lost TP easily. The treatment mixed with 20% or 30% of rice straws was the best on the treatment capacity and the quality of vermi- composting.
