风沙半干旱区是我国旱作农业典型区之一，既是我国重要的粮食生产区，又是我国生态环境最脆弱的地区之一。玉米/花生间作是区域防治农田风蚀和提高农田生产力的主要种植模式之一。之前，区域对玉米/花生间作研究多集中在防治农田风蚀效果及其作用机制方面，对玉米/花生间作提高农田生产力的作用机理研究较少。本项研究在申请人及研究团队现有研究基础上，依托农业部阜新农业环境与耕地保育科学观测实验站研究平台，系统研究不同田间配置作物光合生理适应与作物群体光能高效截获利用、土壤水分空间动态分布特征与种间高效利用，以及不同田间配置、不同氮素水平和种间隔根处理间作群体生物固氮与氮素种间优化利用，探清玉米/花生间作提高农田生产力的机理，在此基础上建立高生产力群体生长发育模型，为区域旱作农田玉米/花生间作种间合理配置与持续增产提供理论基础。

The sandy and windy semi-arid area is one of the typical dry farming region in China. It is not only an important food production area, but also one of the most vulnerable areas in ecological environment. The maize/peanut intercropping is a kind of planting patterns, which control regional farmland wind erosion and improve the agriculture productivity. To date, most of the studies are focus on the effect and mechanism of prevention of farm land erosion, however, the studies on mechanism of farmland productivity improving under the condition of maize/peanut intercropping is still lacking. Based on the existing research, relying on the platform of Fuxin Scientific Observing and Experimental Station of Agro-Environment and Arable Land Conservation, Ministry of Agriculture, P.R.China, this study systemically studies the photosynthetic physiological adaptation of crops in different field configurations and efficient utilization and interception of light of crop groups, dynamics distribution of soil moisture and efficient use in interspecies, and optimal utilization of nitrogen fixation and nitrogen in interspecies of intercropping crop groups with different field configurations, different nitrogen levels as well as different root isolation. Besides, this study makes clear the mechanism of improving agricultural productivity through maize /peanut intercropping. Based on this, we can establish growth and development model of the crop groups with high productivity, and provide the theoretical foundation for reasonable configuration and continuous production in interspecies of maize /peanut intercropping in dry farmland.
