【摘要】 采用模糊综合评价法,建立了包括社会、经济和生态环境3个方面共8项指标的多因素二级评价指标体系,定量评价沧州市潮土区金丝小枣(Ziziphus jujuba)施入微生物菌剂减量施氮的社会效益、经济效益、生态环境效益以及综合效益,以期筛选适合该地区的微生物菌剂与无机氮肥配施的最佳配比。结果表明,80%无机氮肥+微生物菌剂处理的社会效益、经济效益、生态环境效益以及综合效益均较高。更多还原

【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.更多还原
