摘　　要：为给烟-蒜轮作周年养分的统筹施用提供参考,研究氮钾配比对烤烟生物性状、生物量、产量产值及大蒜产量产值的影响。结果表明:烤烟季中氮高钾(N 7.2kg/667m^2,P2O5 6kg/667m^2,K_2O27.2kg/667m^2)配比的最大叶长、最大叶宽分别为76.1cm和29.2cm;叶片生物量最高,干重达0.32kg/株;上等烟比例最高,达35.7%;产值最高,为2 468.8元/667m^2。后茬大蒜是中氮低钾(N 16.8kg/667m^2、P_2O_56kg/667m^2、K_2O 8.8kg/667m^2)配比的蒜薹、蒜头产量产值最高,产量分别为230.85kg/667m^2和157.49kg/667m^2,产值分别为692.56元/667m^2和787.45元/667m^2。中氮高钾区烟-蒜轮作两季的产值为3 948.8元/667m^2,纯收入为993.8元/667m^2。The effects of different nitrogen to potassium ratios on biological traits, biomass, yield and output value of tobacco and garlic were studied to provide references for nutrient application of tobacco and garlic under the rotation pattern. Results： The maximum leaf length, maximum leaf width, leaf biomass/ plant （dry weight）, first-class tobacco proportion and output value of tobacco applied with the fertilizer combination（N 7. 2 kg/667m^2, P2O,5 6 kg/667m^2 and K2O 27.2 kg/667m^2） were 76. 1 cm, 29. 2 cm, 0.32 kg, 35. 7% and 2 468. 80 Yuan/667m^2 respectively and the leaf biomass, first-class tobacco proportion and output value were the highest among different treatments. The highest yield and output value of garlic sprout and garlic bulb under the application combination（N 16. 8 kg/667m^2, P2O5 6 kg/ 667m^2 and K2O 8.8 kg/667m^2） were 230.85 kg/667m^2 and 157.49 kg/667m^2, 692. 56 Yuan/667m^2 and 787. 456 Yuan/667m^2 separately. The output value and net income of tobacco and garlic applied with the fertilizer cornbination（N 7.2 kg/667m^2 , P2O5, 6 kg/667m^2 and K2O 27.2 kg/667m^2） were 3 948.81Yuan/ 667m^2 and 993.80 Yuan/667m^2 respectively,
