不同施氮水平对不同烤烟品种产质量的影响

Effects of Nitrogen Application Rate on Yield and Quality of Different Varieties of Tobacco

[目的]为了摸清示范良种YN105、中烟101和豫烟10号适宜施氮水平。[方法]对烤烟品种YN105、中烟101和豫烟10号进行不同施氮水平试验。[结果]对不同品种的适宜施氮量来说,YN105品种C施肥水平较适宜,中烟101品种A施肥水平较适宜,豫烟10号品种B施肥水平较适宜;从产值结果来看,豫烟10号品种各处理产值最高,中烟101品种的产值最低。[结论]豫烟10号施纯氮67.5kg/hm^2可进一步示范推广。

[ Objective] The research aimed to find out the appropriate N rate of model seed YN105, Zhongyau101 and Yuyan10. [ Method ] The different nitrogen level experiment on Flue-cured tobacco varieties YN105, Zhongyan101 and Yuyan10 was carried out. [ Result] For different varieties of appropriate application rate, C fertilizer level of YN105 variety was more appropriate, A fertilizer level of Zhongyan 101 variety was relatively appropriate, and B fertilizer level of Yuyan10 variety was relatively appropriate. From the output result, the output of YuyanlO variety was the highest, and that of Zho1ngyan101 variety was the lowest. [ Conclusion] Yuyan10 variety can be further demonstrated and promoted in 67.5 kg/hm2 nitrogen level.
