  We studied the effects of rotation and interplanting on soil bacterial communities and crop yields using cucumber as the main vegetable. Onion and garlic were used as interplanting species, and wheat, soybean, villose (more commonly, villous) vetch, clover, and alfalfa were used as rotation plants. T-RFLP techniques were used to show the effects of rotation and interplanting systems on diversity index and richness index of cucumber rhizosphere soil bacterial communities. The results showed that both rotation and interplanting systems increased the richness index and diversity index of soil bacterial community structures, except where alfalfa was used as the rotation plant. The diversity index of the cucumber rhizosphere bacterial community structure was highest in the wheat rotation cropping system, and the richness index of soil bacteria was highest in wheat and clover rotations and in the onion interplanting system. Our results show that rotation and interplanting systems beneficially altered community structures of dominant soil bacteria, and increased cucumber yield and soil bacterial diversity. The best cultivation system to increase cucumber yield utilized onion as an interplanting species and wheat as a rotation plant.
