对豆粕有机质发酵液的发酵条件进行优化，为香蕉枯萎病提供稳定、有效的生物学防治方法。研究采用单因素试验考察不同因素对豆粕有机质发酵的影响，运用正交试验对实验条件进行优化，结果发现，豆粕有机质最佳发酵工艺为豆粕有机质混悬液稀释5倍，红糖浓度为2.0 g/100 mL发酵15 d。为豆粕发酵液进行规模化生产提供了数据支持。
The fermentation conditions for producing soybean meal fermented liquid was optimized and used to control banana fusarium wilt. Single factor experiment was designed to determine the effect of different factors on the soybean meal fermentation, based on which orthogonal experiments were arranged to optimize the experimental conditions. Some factors that had higher influence on the fermentation of soybean meal organic matter were selected. The orthogonal experiment showed that soybean meal suspension was diluted at a ratio of 1:5 with the brown sugar concentration of 2.0 g/100 ml and fermented for 15 days to produce better soybean meal fermented liquid. This provided data support for commercial production of soybean meal fermented liquid.
