Abstrct：

    The aim of this study was to investigate the effect of rotation model ‘rice-cabbage-wheat and green manure’ on crop cultivation as well as environment. The results showed the yield of crops with conventional cultivation still had significant incensement than environmental friendly treatment after rotation. According to the evaluation of two-year study, 575 kg•ha^-1 (5.9%), 3647 kg•ha^-1 (10.9%), and 852 kg•ha^-1 (14%) were increased in rice, cabbage, and wheat, respectively. For environmental changes, there were not significant differences in soil pH, EC, total nitrogen content, and organic content. For the pest and disease happened such as rice-stem borer, downy mildew, black rot, and moth in cabbage, and wheat border, there were also not significant difference between conventional and friendly treatments. Therefore, in consideration of different regions, different climate conditions as well as different agricultural products, the rotation model of present study still required further long-term evaluation to create the maximum income.

Keywords: Cultivation, Environmental friendly, Rotation cropping.
