摘　　要：[Objective] The aim was to evaluate the feasibility of biotechnology fulvic acid produced by microbial community LCM9 by the use of corn straws as substrate and its application effect.[Method]Microbial community was obtained from the nature samples,and corn straws were used as fermentation substrate.The yield of biotechnology fulvic acid and its application effect was evaluated.[Result]The yield of biotechnology fulvic acid was up to 15.7% when the water content was 75.0% and fermented after 7 d using corn straws as the only source of nutrition.After 500 mg/kg of biotechnology fulvic acid was added for 5 d,the root length and bud length could be increased by 59.1% and 97.1%,respectively.[Conclusion]A higher yield of biotechnology fulvic acid could be obtained by the method in this experiment and the product could enhance the growth of wheat seedlings.[目的]研究利用微生物菌群发酵玉米秸秆生产生化黄腐酸及其应用效果。[方法]从自然界直接筛选能高效降解玉米秸秆的微生物菌群,以玉米秸秆为原料,研究利用菌群发酵玉米秸秆生产生化黄腐酸的产量,并对产品的实际应用效果进行了探讨。[结果]利用获得的菌群LCM9,以玉米秸秆为唯一营养源,在水分含量为75.0%时,发酵7d,生化黄腐酸产量可达15.7%。施加500mg/kg生化黄腐酸,培养5d后,小麦种子根长增加59.1%,芽长增加97.1%。[结论]利用微生物菌群发酵玉米秸秆可获得较高产量的生化黄腐酸,且产品对小麦幼苗具有明显刺激生长的效果。
