摘　　要：采用夏玉米高产品种郑单958为材料,研究喷施生长调节剂对玉米生长发育的影响。结果表明,喷施化控剂"康丰利"增加玉米茎粗,缩短基部节间的长度,提高根系干重,增加根长,增强玉米植株的抗倒伏能力,提高产量2.6%。Summer maize variety of Zhengdan958 was used to study the effects of plant growth regulator（PGR） on the growth and development of summer maize. The results showed that the stem thickness was increased, the length of inter-node near the basal part was shorted, root dry mass and root length were increased by the treatment of spraying one kind of PGR-Kangfengli, and increase the plants lodging resistance of maize. The grain yield was also increased to some degree.
