水肥耦合对旱地烟生长、产量、品质及肥料利用率的影响

Effects of Water and Fertilizer Coupling on Growth,Yield,Quality and Fertilizer Utilization Rate of Tobacco in Dry Land

以烤烟品种K326为试验对象,在丘陵旱地研究了水分与肥料耦合对烤烟生长、产量、品质及肥料利用率的影响。结果表明:滴灌与增施肥料的耦合效应明显,能改善烟株的农艺性状,提高烟叶的产量和质量,提高烟株对肥料的利用率,增加烟叶生产的经济效益。

Taking flue-cured tobacco variety K326 as the experimental material,the author studied the effects of water and fertilizer coupling on the growth,yield,quality and fertilizer utilization rate of tobacco in hilly dry land.The results showed that the coupling effect of drip irrigation and increasing fertilizer application rate was obvious,this coupling could improve the agronomic traits of tobacco plants,enhance the yield and quality of tobacco leaves,raise fertilizer utilization rate,and finally increase the economic benefit of tobacco production.
