Abstract: As one of the most important grain crops in the world, the high yield of maize plays a significant role in the food security of China. Practices had shown that rational intercropping can take full advantage of nutrient and water resources and enhance crop yields enormously. This paper summarized the recent progress and implementing achievement in intercropping technology of maize with leguminous crops, wheat, vegetables and other dry land crops. Based on the synthetic evaluation of the literatures, comparing with the monocropping cultivation pattern, the intercropping or interplanting of maize and other dry land crops could not only promote crop output and quality, but also effectively improve the utilization rate of resources was found. It is clearly that expanding and deepening the system study, putting forth effort to establish the technique system and cultivation criterion is vitally important was put forward, And it is necessary and urgently to be solved to transform the research results into operating instructions and cultivation technique for large area of field planting, and to serve for the modern dry land agriculture.
