介绍了玉米叶片及根系早衰的主要影响因素：品种自身遗传、气象环境与土壤肥力以及种植模式、栽培措施等，从宏观以及内在机制上阐述了早衰对玉米产量的显著影响。同时总结了早衰的防治方法，提出了具体的调控措施。除了从品种选育及使用合理的栽培措施调控外，还重点介绍了采用植物生长调节剂调控玉米生长发育进而延缓衰老的措施，并对未来玉米早衰的防治措施进行了展望。

The paper described the main factors that caused the premature aging of maize leaves and roots,such as genetic inheritance of variety,weather conditions,soil environments,cropping patterns etc, and the inherent mechanism of premature senescence and its effects on maize yield. Meanwhile,the de-tailed regulation measures were proposed,including the breeding of resistant varieties,the reasonable cul-tivation measures and the application of plant growth regulators. Finally,the prevention measures to corn premature aging in the future were prospected.
