摘　　要：[目的]完善自育烤烟新品种GZ90和GZ66的配套栽培技术。[方法]对GZ90和GZ66进行不同梯度的施氮量田间试验,探明不同施氮水平对其生长发育、产量及质量的影响。[结果]自育烤烟新品种GZ90在施纯氮135 kg/hm2时,生长发育较好,产值最高,烟叶化学成分协调,在施纯氮120 kg/hm2时均价和上中等烟比例最好;施纯氮135 kg/hm2时,自育烤烟新品种GZ66的生长发育较好,上中等烟比例、产量、产值及均价最高,烟叶化学成分协调,可以满足优质烟叶生产的要求。[结论]自育烤烟新品种GZ66和GZ90的最佳施纯氮量为135 kg/hm2。[Objective]To improve the supporting cultivation techniques of new flue-cured tobacco varieties GZ90and GZ66.[Method]Field experiments were carried out on GZ90and GZ66with different levels of nitrogen application,and the effects of different levels of nitrogen application on the growth,yield and quality were explored.[Result]GZ90had better growth and development when applied with135kg/hm^2of pure nitrogen,and had the highest output value.When nitrogen was applied to135kg/hm^2,GZ66had better growth and development,with the highest proportion,yield,output value and average price of upper medium tobacco.The coordination of chemical composition of GZ66tobacco leaves can meet the requirements of high-quality tobacco leaf production.[Conclusion]The optimum nitrogen application rate of the new flue-cured tobacco varieties GZ66and GZ90is135kg/hm^2.
