化肥减量配施有机肥结合化控对高密度栽培玉米抗倒伏能力的影响OA
Effect of Reduced Chemical Fertilizer Combined with Organic Fertilizer and Chemical Control on the Lodging Resistance of High-Density Cultivated Maize
为探究高密度栽培下不同施肥与化控措施对玉米抗倒伏能力的影响,以"菏玉158"玉米品种为材料,在山东巨野县设置5个处理,研究各处理对玉米茎秆物理性状、抗倒伏力学指标及产量构成的影响.结果表明,化肥减量30%配施有机肥并结合矮壮素喷施处理(T4)能显著增强茎秆强度,降低倒伏率,是巨野县地区高密度玉米种植的抗倒伏优化模式.
To investigate the effects of different fertilization and chemical control measures on maize lodging resistance under high-density cultivation,the"Heyu 158"maize variety was used in five experimental treatments established in Juye County,Shandong Province.The study examined the impacts of each treatment on maize stem physical traits,lodging resistance mechanical indicators,and yield components.Results demonstrated that reducing chemical fertilizer by 30%,combining with organic fertilizer,and applying paclobutrazol spray(T4)significantly enhanced stem strength and reduced lodging incidence,establishing this as an optimized lodging resistance management strategy for high-density maize cultivation in Juye County.
