[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.
