摘　　要：极端天气造成的玉米倒伏会严重影响粮饲兼用型玉米产量。以粮饲兼用型玉米品种鲁宁184为材料,设4种化学调控剂处理,以喷施清水为对照,探究在不同化控处理下粮饲兼用型玉米品种鲁宁184的生长特性和产量。结果表明,与对照相比,不同化控剂可有效调节玉米生长性状,主要降低株高,增加次生根条数来增强抗倒伏性;喷施多效唑或胺鲜乙烯利处理可以提高植株鲜干重产量,保持较高穗粒数,达到增产和抗风险的目的,推荐在生产中使用。Maize lodging caused by extreme weather will seriously affect the harvest yield of maize for both grain and forage.The growth characteristics and yield formation of the grain-forage maize variety Luning 184 under different chemical regulators treatments were investigated by using four chemical regulators and spraying water as the control.The results showed that compared with the control,different chemical regulators could effectively adjust the growth traits of maize,mainly reduce plant height,increase the number of secondary roots to enhance lodging resistance,and spraying paclobutrazol or amine fresh ethephon treatment could increase the yield of fresh and dry weight of plants,maintain a higher number of grains per panicle,and achieve the purpose of increasing yield and resistance,which was recommended to be used in production.
