摘　　要：为明确化肥减施对甘蓝生长发育的影响,采用轻简化追肥措施(水肥一体化),研究化肥减施对甘蓝株高、品质、产量等指标的影响。试验结果表明,在露地甘蓝生长过程中,不同化肥减施处理对甘蓝生长发育产生了较大影响,与CK(667 m^(2)基施硫酸钾型复合肥50 kg+追施尿素25 kg)和T_(2)(667 m^(2)基施缓释肥30 kg+追施大量元素水溶肥18 kg)相比,T_(1)(667 m^(2)基施缓释肥40 kg+追施大量元素水溶肥18 kg)不仅能提高甘蓝植株长势、改善甘蓝品质,还能提高甘蓝的单株质量及产量。因此,认为T_(1)施肥方式(化肥减施22.7%)能够在甘蓝生产中推广应用。In order to study the effects of reducing chemical fertilizer on the growth and development of cabbage in the field,the light and simplified top dressing measures(integration of water and fertilizer)were adopted,and the plant height,quality and yield of cabbage were measured in this paper.The results showed that different precision fertilization treatments had great impacts on the growth and development of cabbage in the open field.Compared with CK(base fertilizer:potassium sulfate compound fertilizer 50 kg/667 m^(2),top dressing:urea 25 kg/667 m^(2))and T(base fertilizer:slow release fertilizer 30 kg/667 m^(2),top dressing:macro element water soluble fertilizer 18 kg/667 m^(2)),Ttreatment(base fertilizer:slow release fertilizer 40 kg/667 m^(2),top dressing:macro element water soluble fertilizer 18 kg/667 m^(2))not only improved the quality of cabbage to a certain extent,but also increased the single plant weight and yield of cabbage.Therefore,Tfertilization method(the amount of chemical fertilizer decreased by 22.7%)could be applied in cabbage production.
