| Abstract: | Legume-gramineae intercropping system, as a model of sustainable agricultural development, plays an important role in ensuring grain yield and maintaining nitrogen balance. This paper reviewed the effects of legume-gramineae intercropping on the legume nitrogen fixation, crop nitrogen uptake, and soil nitrogen balance. Rational legume-gramineae intercropping could promote the legume biological nitrogen fixation, improve crops of legume-gramineae intercropping system nutrient use efficiency, reduce soil nitrogen loss, and benefit the protection of cropland ecological environment and the maintenance of agricultural sustainable development. Then, high yield and high efficient cultivation models and technique measures specially suitable for different ecological agricultural divisions in Gansu province were summarized. Finally, the paper identified some important future directions of intercropping research and practical uses, and it would be useful to further develop suitable machinery for the legume-gramineae intercropping system, which would meet needs of agricultural development in new stage and simultaneously increase of farmers’ income. It also played an important role in the establishment of modern high yield and high-efficient technique and cultivation crop system. |
