不同有机无机肥配施对烤烟产量和品质的影响

[目的]为了研究有机无机肥配施对烟株生长及烟叶产量、品质的影响.[方法]以烤烟K326为材料,以不同有机无机肥配施为研究因素,采用随机区组设计开展研究.[结果]在施纯氮相同的基础上,施用有机肥占总施肥量25％～50％、施用无机肥占总施肥量50％～75％时有利于烤烟烟株的生长发育,且烟叶产量、产值较高,外观质量也较好.[结论]该研究可以为烤烟的施肥技术提供理论依据.

Effects of Different Combined Application of Organic Fertilizer and Inorganic Fertilizer on Yield and Quality of Flue-cured Tobacco

[Objective] The research aimed to study the effects of combined application of organic fertilizer and inorganic fertilizer on the growth,yield and quality of flue-cured tobacco.[Method] Flue-cured tobacco K326 was taken as material,and combined application of different organic and inorganic fertilizers was study factor.Randomized block design was carried out.[Result] On the basis of the same amount of pure nitrogen,organic fertilizer of 25％ ～50％ and inorganic fertilizer of 50％ ～ 75％ could promote the growth and the development of the flue-cured tobacco.The yield and production value of tobacco were high,and the appearance quality was better.[Conclusion] The study could provide the theoretical basis for the fertilization technology of the flue-cured tobacco.
