摘　　要：[目的]明确德宏烟区中等肥力土壤下,氮磷钾施用量对烤烟红花大金元产质量的影响。[方法]在云南省梁河县勐养镇芒轩村进行了红花大金元品种不同施肥量的小区对比试验。[结果]随着施氮量和氮磷钾比例的增加,上、中、下3个部位的烟叶成分协调性趋于较好,红花大金元生育期、烟叶外观质量没有显著差异,但产量、产值、均价与之呈正相关,其中A3B2处理产量、产值、均价最高,但是化学成分较不协调。[结论]以纯氮用量105 kg/hm2指导红花大金元施肥,不仅提高烟叶的产质量,还可提高效益。[Objective]Based on moderate fertility soil at Dehong smoke zone,to further clarify the influence of NPK dosage on yield and quality of Honghuadajinyuan tobacco.[Method] A comparative experiment was conducted to compare the different fertilization rates jinyuan tobacco in Mangxuan Village,Mengyang Town,Lianghe County,Yunnan Province.[Result]With the increase of N application rate and the ratio of NPK,the components of tobacco leaves in the upper,middle and lower parts tended to be better,growth period,the appearance of the leaves of Honghuadajinyuan had no significant differences,but they were closely relative to yield,output,average price.The treatment of A3B2 reached highest yield,output and average price,but the chemical composition was not harmonious.[Conclusion]Using 105 kg/hm-2 pure nitrogen to guide the fertilizing of Honghuadajinyuan not only improve the quality and yield of tobacco leaves,but also improve the efficiency.
