Abstract: In order to find out the optimal chemical regulator for maize growth, six maize hybrid cultivars were used as the main factor and five chemical regulators were used as the second factor, the yield of different maize cultivars under the treatment of different chemical regulators were analyzed by randomized block design experiment. The results showed that the yield increase rate of‘Xieyu 5’was more obvious than that of other cultivars, and‘Xieyu 3’was not suitable for chemical regulator treatment. Yuhuangjin, CCC and water spraying treatment could not improve the yield significantly, and Gaoyujin had a negative effect on yield. CCC could increase the yield of‘Xieyu 4’and‘Taiyu 339’, and Huangjinyu could increase the yield of‘Xieyu 5’ and‘Xianyu 335’. Chemical regulators had no significant effect on the yield of maize and different chemical regulators were suitable for different maize cultivars.
