摘　　要：以不同重茬肥配方对重茬栽培烤烟前期农艺性状的影响为基础,探索不同配方对烤烟生长的影响,以期为开发烤烟重茬肥提供理论依据。试验在田间条件下,设置对照B1无肥处理,B2当地常规施肥,B～B5为新研制重茬肥配方,纯氮用量为51.5kg·hm-2,3次重复。试验结果表明,移栽后第3周,各处理和对照之间植株高度和叶片长度差异不大,B5处理的茎粗度和叶片宽度与对照之间差异显著,并且2项指标高于常规施肥处理;第5,7周,各处理苗高和茎粗显著高于对照,B3和B5处理优于常规施肥处理;烟叶长宽生长以B5处理促进作用最佳,极显著高于对照,并且优于常规施肥处理。综合分析认为,B5处理的重茬肥配方对重茬烤烟前期农艺性状影响最佳,有望成为烤烟重茬专用肥配方。This study based on effect of pre-cropping cultivation of agronomic traits of flue-cured tobacco under different fertilizer formulas,different formulas on the growth of flue-cured tobacco were explored,a theoretical basis for development fertilizer of tobacco cropping was provided.Test in field conditions,set the control B1 no fertilizer,B2 local conventional fertilization,B3-B5 for the new development cropping fertilizer formula,the amount of nitrogen was 51.5 kg·hm-2,repeat 3 times.The results showed that 3 weeks after transplanting,between the treatment and control of plant height and leaf length was no insignificant differents,B5 treatment stem diameter and leaf width were significantly different between the control,and the two indexes are higher than conventional fertilization.At the 5,7 weeks,height and stem diameter of each treatment were significantly higher than the control,B3,B5 treatment exceed than conventional fertilization.Leaf length and width of growth the best treatment is B5,was significantly higher than the control,and superior to conventional fertilization.Comprehensive analysis,B5 cropping fertilizer formulas on agronomic traits of pre-cropping tobacco best,this was expected to become special tobacco cropping fertilizer formulas.
