FG-1烤烟新品系配套栽培技术研究

Study on Cultivation Technology of New Flue-cured Tobacco Variety FG-1

[目的]研究烤烟新品系FG-1的栽培特点,形成其配套栽培技术。[方法]在贵州省设置不同施氮量与不同密度试验,探讨烤烟新品系FG-1的最佳种植密度与最佳施氮量。[结果]不同密度、施氮量对该品种大田生育期影响不明显;施氮量在112.5kg/hm2田间长势最好、产量最高;密度13 000株/hm2,施纯氮量105.0 kg/hm2的处理下,产量适中,上等烟率、上中等烟率、产值明显高于其他处理;综合表现最好的是密度13 000株/hm2,施氮量105.0 kg/hm2的处理。[结论]FG-1烤烟新品系最佳种植密度为13 000株/hm2,最佳施氮量为105.0 kg/hm2。

[Objective] The aim was to form the corresponding cultivation and application lechnology of the new flue cured tobacco variety FG-1. [Method] The effects of planting density and nitrogen application rate on the growth and development and yield of the new title cured tobacco variety FG-I were researched, by setting up different planting densities and nitrogen application rates experiments in Guizhou Province. [Result] The effect of the different planting densities and nitrogen applying rates on the FG-1 were not distinct. The FG-1 has most desirable growth and yield with 112.5 kg/hm2 nitrogen applying. And with treatment of spacing of 70 ore, l lO cm row spacing planting and 105.0 kg/hm2 nitrogen applying, the high- middle -quality ratio and output of FG-1 were higher than that of other treatments, and the overall performance was the best. [Conclusion] The result of the study showed that FG-I had a better grew and economic indicators with spacing of 70 cm, 110 cm row spacing planting and 105.0 kg/hm2 nitrogen applying.
