摘　　要：为了探索降低烤烟化学钾肥用量的农艺措施,通过大田试验研究了施用生物钾肥后减少化学钾肥对土壤养分和烤烟产质量的影响。结果表明,施用生物钾肥后减少化学钾肥施用量不会降低土壤中速效钾及其他主要养分含量,烟株正常生长发育,烟叶经济效益好,化学成分含量适宜、比例协调,综合两年试验结果,减K2O 7%的处理产量和质量等指标均优于其他处理。因此认为,施用生物钾肥后减少化学钾肥用量10%左右较为适宜。In order to explore the agricultural measures for decreasing the chemical potassium rates,the effects of decreasing chemical potassium after application of biotic potassium on soil nutrient contents and yield and quality of flue-cured tobacco were studied by field experiments.The results showed that application of decreasing chemical potassium after biotic potassium application could not reduce contents of available potassium and other major nutrients in soil.It had no significant effects on the growth of tobacco plant,but maintained better economic characters and chemical components of tobacco leaves.The yield and quality index in the treatments of decreasing K 2 O at 7% was better than other treatments.Therefore,the treatment of decreasing chemical potassium（K 2 O） at 10% after application of biotic potassium was appropriate for flue-cured tobacco.
