摘 要:采用田间试验方法比较了不同施肥量(施氮量分别为90.0、97.5和105.0 kg/hm^2,氮磷钾比例为1∶1.5∶3.5)处理对烟叶产量、质量的影响。结果表明,处理3(施氮量105.0 kg/hm^2)的烟叶产量分别比处理1(施氮量90.0 kg/hm^2)和处理2(施氮量97.5 kg/hm^2)增加了11.63%和6.05%,处理2的产值最高,分别比处理1和处理3增加了6.76%和0.87%。处理2的上等烟率、上中等烟率和上部烟叶上等烟率分别达到了48.59%、91.49%和60.49%。随着施肥量的增加,烤烟单叶重、烟梗重以及烟叶还原糖、烟碱、总氮、钾的含量呈现出逐渐增加的趋势,以处理2的烟叶总糖含量最高,而氯的含量则最低。总之,针对利川市烟区而言,纯氮磷钾用量为97.5、146.25、341.25 kg/hm^2时,能够获得较高的产量、质量和经济效益。The field experiment were carried out to study the effect of different fertilizer application(the quantity of nitrogen was90.0,97.5,105.0kg/hm2;the ratio of nitrogen,phosphorus and potassium was1∶1.5∶3.5)on the yield and upper leaves quantity of flue cured tobacco.The results list as follow:compared with treatment1(N90.0kg/hm2)and treatment2(N97.5kg/hm2),the yield of flue cured tobacco of treatment3(N105.0kg/hm2)was increased by11.63%and6.05%.And the production value of treatment2increased by6.76%and0.87%compared with treatment1and treatment3,respectively.The superior rate,medium-superior rate and superior rate of upper tobacco of treatment2were48.59%,91.49%and60.49%,respectively.With the increase of fertilizer application,single leave weight,stem weight,content of reducing sugar,nicotine,total nitrogen and potassium of flue cured tobacco showed a gradually increasing trend;among which total sugar content of treatment2was the highest,while chlorine content was the lowest.In conclusion,when the nitrogen,phosphorus and potassium fertilizer application were97.5,146.25,341.25kg/hm2in Lichuan city,higher yield,quality and economic benefits of flue cured tobacco could be achieved.
