Abstract: The fuzzy comprehensive evaluation method was applied in this study. The multi-factor secondary evaluation index system was established, which included 8 indexes from 3 aspects of society, economy and ecological environment to quantitatively evaluate the reduction of nitrogen application by microbial inoculation of Ziziphus jujuba in the fluvo-aquic soil area of Cangzhou, in order to screen the best ratio of microbial inoculants and nitrogen fertilizers suitable for the area. The results showed that the social, economic, ecological environment and comprehensive benefits of 80% nitrogen fertilizer+microbial agent treatment were higher.

Key words: Ziziphus jujuba, microbial agents, amount of nitrogen fertilizer, benefit evaluation, fuzzy comprehensive evaluation method
