摘要
综述了钾对烤烟产量和品质的影响,分析了根外追施钾肥对烤烟生长发育、产量和品质及土壤养分的影响,比较了根外追肥钾肥与常规施用钾肥的效果,对烤烟根外追施钾肥研究方向进行了展望。
Effects of potassium on the yield and quality of flue-cured tobacco were discussed in this paper. Effects of spraying potassium fertilizer on yield and quality of flue-cured tobacco were reviewed. The fertilizer efficiency of leaf-spraying potassium and conventional application were compared. The research trends of leaf-spraying potassium fertilizer on flue-cured tobacco were prospected in the end.
