Effects of Different Fertilization Application Methods and Hole Depths on Yield and Quality of Flue-cured Tobacco

[目的]探索不同施肥方法和打孔深度对烤烟产量和质量的影响。[方法]于2016年在恩施利川开展不同施肥方法和打孔深度对烤烟产量和质量的研究。[结果]综合施肥方式、打孔深度对烤烟产量、产值、内在化学成分、评吸质量的影响,确定基肥施用方式可采用不掏沟施肥,打孔深度以15～17 cm为宜。[结论]该研究为提高烤烟产量和产值提供理论依据和技术支持。

[Objective]To research the effect of different fertilization application methods and hole depths on yield and quality of flue-cured tobacco.[Method]The experiments of different base fertilization application methods and hole depths were done in Lichuan in 2016.[Result]Considering different fertilization application methods and hole depths on yield,production value,intrinsic chemical composition and smoking quality of the flue-cured tobacco,the fertilization application method was advisable to fertilize land without furrow,and the depth of hole was advisable with 15-17 cm.[Conclusion]The study provides theoretical basis and technical support for improving the yield and output value of flue-cured tobacco.
