摘　　要：为不同玉米品种寻找出其最适的化控剂,以6种不同的玉米杂交品种为主因素,以5种不同的玉米化控剂处理为次因素,采用随机区组设计研究不同玉米品种在不同化控剂处理下各小区产量的变化情况。研究结果表明:‘协玉5号’品种在化控剂处理下产量增加较其他品种显著,‘协玉3号’品种不适合化控处理;玉黄金、矮壮素化控剂以及喷水处理并不能显著提高产量,高玉金对产量增加有负效应;同时,‘协玉4号’、‘太玉339’品种喷矮壮素能提高产量,‘协玉5号’、‘先玉335’品种喷玉黄金能增产。化控剂对提高玉米产量作用不明显,不同的玉米品种适用不同的化控剂。In order to find out the optimal chemical regulator for maize growth, six maize hybrid cultivars wereused as the main factor and five chemical regulators were used as the second factor, the yield of different maizecultivars under the treatment of different chemical regulators were analyzed by randomized block designexperiment. The results showed that the yield increase rate of‘Xieyu 5＇was more obvious than that of othercultivars, and‘Xieyu 3＇was not suitable for chemical regulator treatment. Yuhuangjin, CCC and waterspraying treatment could not improve the yield significantly, and Gaoyujin had a negative effect on yield. CCCcould 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 chemicalregulators were suitable for different maize cultivars.
