The invention relates to an intercropping method for improved maize hybrids. In the aspect of breeding science, an 'intercropping method for improved uniparental maize hybrids' is provided to improve the single parent of maize varieties popularized for production and select improved uniparental maize hybrids, a reasonable intercropping match is made according to the features of the improved hybrids and original varieties, and finally, high and stable yield of a maize intercropping group is realized. The intercropping method breaks the limitations on selecting maize intercropping candidate varieties, solves the problems of inconvenient production management and inconsistent seed commodity during simple mechanical mixing of maize of different genes and has significance on high and stable yield, high quality and high efficiency of maize.
