以黄瓜为主要蔬菜，研究了轮作和间作对土壤细菌群落及作物产量的影响。洋葱和大蒜被用作套种物种，小麦、大豆、长绒毛（更常见的是长绒毛的）野豌豆、三叶草和苜蓿被用作轮作植物。采用T-RFLP技术研究了轮作和间作对黄瓜根际土壤细菌群落多样性指数和丰富度指数的影响。结果表明，除苜蓿轮作外，轮作和间作均提高了土壤细菌群落结构的丰富度指数和多样性指数。黄瓜根际细菌群落结构多样性指数以小麦轮作最高，土壤细菌丰富度指数以小麦与三叶草轮作和洋葱间作最高。结果表明，轮作和间作有利于改变土壤优势细菌群落结构，提高黄瓜产量和土壤细菌多样性。提高黄瓜产量的最佳栽培制度是利用洋葱作为间作种，小麦作为轮作植物。
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.
