    摘要:

    玉米早衰是一个很复杂的问题,影响玉米的产量和品质,备受人们关注。本文从玉米衰老与氮素营养的调节,水分胁迫与玉米衰老发生的关系,植物内源激素与玉米衰老发生的关系及叶片衰老过程中的根-叶互作关系等四个方面,综述了栽培技术对延缓叶片衰老的积极作用。并对今后如何从栽培和耕作学角度来研究玉米衰老问题进行了展望,以期为解决生产中玉米早衰问题提供帮助。

    Abstract:

    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.
