摘　　要：为了对白酒酒糟进行资源化利用,该研究分别利用纤维素降解菌株A5、B2混合发酵(1∶1)酒糟A及酒糟B制备2种酒糟有机肥(处理组1有机肥、处理组2有机肥),再将筛选的固氮菌N1、解磷菌P1、P2接种至酒糟有机肥中制备生物有机肥(1号生物有机肥、2号生物有机肥),对酒糟有机肥堆肥过程中水分、温度、pH值及发芽指数等指标进行检测,并对酒糟有机肥、生物有机肥的品质进行分析。结果表明,纤维素降解菌株的加入对堆积过程中水分、温度和pH变化趋势没有影响,但能提高酒糟有机肥的发芽指数。处理组1、处理组2酒糟有机肥的发芽率、发芽指数均较高,分别为98.63%、90.64%,97.72%、79.86%。1号、2号生物有机肥的发芽率分别为100%、95%,发芽指数分别为82.99%、90.40%,生物有机肥发芽率比酒糟有机肥均有所提高,其理化指标均符合相关行业标准。与未添加生物有机肥相比,1号生物有机肥添加量为10%~80%时,可促进高粱苗株的生长,其中,生物有机肥添加量为40%时,高粱苗株长势较好。In order to realize the resource utilization of Baijiu distillers'grains,two kinds of distillers'grains organic fertilizer(treatment group 1 organic fertilizer and treatment group 2 organic fertilizer)were prepared by distillers'grains mixed fermented with cellulose degrading strains A5 and B2(1∶1).Then,the bio-organic fertilizers(No.1 bio-organic fertilizer and No.2 bio-organic fertilizer)were prepared by the inoculation with the screened nitrogen fixation bacteria N1,phosphorus solubilizing bacteria P1 and P2 into distillers'grains organic fertilizer.The indexes including moisture,temperature,pH and germination index in the composting process of distillers'grains organic fertilizer were detected,and the quality of distillers'grains organic fertilizer and bio-organic fertilizer was analyzed.The results showed that the addition of cellulose-degrading strains had no effect on the trend of water,temperature and pH,but could increase the germination index of distillers'grain organic fertilizer.The germination rate and germination index of distillers'grains organic fertilizer in treatment group 1 and treatment group 2 were 98.63%,90.64%,97.72%and 79.86%,respectively.The germination rate of No.1 and No.2 bio-organic fertilizers were 100%and 95%,and the germination index was 82.99%and 90.40%,respectively.The germination rate of bio-organic fertilizers was higher than that of distiller's grains organic fertilizers.Their physicochemical indexes were in line with relevant industry standards.Compared with no bio-organic fertilizer addition,the growth of sorghum seedlings could be promoted when the bio-organic fertilizer No.1 addition was 10%-80%,and the growth of sorghum seedlings was better when the bio-organic fertilizer addition was 40%.
