摘　　要：矮化密植栽培技术是一种高产技术,可通过化控措施有效地调节植株高度,增强茎杆韧性,增加气生根条数,防止玉米因密度过大导致茎杆瘦小、纤维含量低以及遇大风天风造成倒伏现象,有效降低顶端优势,控制养份流失,增加雌穗生长发育。从科学整地、品种选择、合理密植、测土配方施肥、病虫害综合防治、收获几个方面,详细介绍了大田玉米矮化密植高产栽培技术。Dwarfing and dense planting cultivation technology is a high-yield technique.By effectively applying chemical control measures to adjust plant height,enhance stem toughness,increase the number of aerial roots,prevent maize from becoming thin and thin due to high density,low fiber content,and lodging caused by strong winds.At the same time,it effectively reduces apical dominance,controls nutrient loss,and increases the growth and development of female ears.Therefore,this paper briefly introduced highyield cultivation techniques for maize in the field from several aspects such as scientific land preparation,variety selection,reasonable close planting,soil testing and fertilization,comprehensive pest control,and harvesting.
