Premature senescence of maize was a complicated issue, which influenced the yield and quality of maize and attracted greater attention. The active role of cultivation techniques in delaying leaf senescence of maize was reviewed and discussed in the paper from the view of the effects of N application on maize senescence, the relationship between occurrence of maize senescence and soil water stress, plant endogenous hormones, as well as interaction between roots and leaves during period of maize senescence. The prospective research on maize senescence combined with the crop cultivation and farming system was forecasted in the end, which would provide support for preventing premature senescence of maize in agricultural production.
