摘要： 为减少畜牧业和食用菌生产中农业废弃物对环境造成的污染,循环利用农业废弃物资源,通过盆养和堆肥自由选择摘试验要,就平菇废菌渣搭配猪粪、牛粪饲喂蚯蚓的生长和繁殖效果及蚓粪肥效开展了相关研究。结果表明:猪粪和牛粪在平菇废菌渣基质中的搭配能显著提高蚯蚓的生长繁殖效率,其中20%的猪粪和40%的牛粪质量配比最适宜蚯蚓的生长与繁殖。饲喂蚯蚓后各组基质的有机质和碳氮比均大幅下降,除40%牛粪组中的全氮含量未有显著变化,20%猪粪组全氮含量有显著降低外,各基质组中的全氮、全磷、全钾和速效氮、速效磷、速效钾的含量在蚯蚓消解后均有显著提高。蚯蚓体内未检测出汞、铅;铜和锌等重金属含量基本符合饲用安全标准;蚓粪经适当调制后适宜做优质有机肥。关键词　蚯蚓;平菇菌渣;畜禽粪便;再生利用;有机肥

Abstract: In order to recycle the agricultural waste resources and to reduce the environmental pollution caused by agricultural waste inanimal husbandry and edible fungi production, the growth and reproduction effect of earthworms and its vermicompost effect were stud-ied by pot culture and free choice experiment. The results showed that the combination of pig dung and cow dung in the medium withPleurotusostreatusresidue could significantly improve the growth and reproduction efficiency of earthworm, the weight proportion of20% pig dung and 40% cow dung was the most suitable for the growth and reproduction of earthworm. The organic matter and C / N ra-tio of earthworm in each group decreased significantly after earthworm digestion, except the total nitrogen content in 40% cow dunggroup and 20% pig dung group. The contents of total N, total P, total K, available N, available P and available K in most substrategroups were significantly increased after earthworm digestion. The contents of mercury and lead in earthworms were not detected; thecontents of heavy metals such as copper and zinc in earthworms met the safety standards for feeding; the vermicompost was a high qual-ity organic fertilizer after being properly prepared.
