【摘要】：以白酒丢糟为主要原料,4种芽孢杆菌、2种霉菌与酿酒酵母为混菌发酵菌株,进行多菌种混菌固态发酵,以发酵产物的腐殖质、全氮、全磷、全钾含量为指标,通过单因素实验和响应面法分析探讨酒糟固态发酵制备有机肥在初始含水量、酒糟量和初始pH的最佳工艺条件.经验证性实验可知预测值与实际值相符,得到最佳工艺条件:初始含水量为60.54%、酒糟量为52.06%、初始pH为7.03,接种量为3%~5%,发酵时间为6 d,发酵产物中腐殖质含量达到17.50%,种子发芽指数GI值达到93.2%,E4/E6值为2.19.
[Abstract]:Four kinds of Bacillus spp and two strains of Saccharomyces cerevisiae were used as the main raw materials for solid-state fermentation of mixed bacteria. The content of humus, total nitrogen, total phosphorus and total potassium of the fermentation product was taken as the index. Single factor experiment and response surface method were used to analyze the optimum conditions for the preparation of organic fertilizer by solid fermentation of distiller's grains in the initial water content, distiller's grains amount and initial pH. The experimental results show that the predicted values are in good agreement with the actual values. The optimum technological conditions were obtained as follows: initial water content 60.54, distiller's grains 52.06, initial pH 7.03, inoculation volume 3 ~ 5, fermentation time 6 days, humus content in fermentation product 17.50 and seed germination index GI 93.2e _ 4 / E _ 6 = 2.19.
