摘　　要：研究了石灰、白云石粉作为酸性植烟土壤改良剂对烟区土壤的改良效果及其对烤烟生长、产量和品质的影响。结果表明,隔年施用白云石粉1125kg/hm2改良土壤酸度效果明显,能促进烟株的生长;与对照相比,产量提高117.45kg/hm2,产值增加1798.05元/hm2,上等烟比例提高3.93个百分点,土壤pH从5.05升至5.36。Lime and dolomite powder were applied to tobacco-planting soils to study their effects on soil pH, flue-cured tobacco growth, yield and quality. The results showed that applying dolomite powder at the rate of 1 125 kg/ha every second year adjusted soil acidity obviously and improved flue-cured tobacco leaf yield and quality. Application of dolomite powder increased tobacco leaf yield by 117.45 kg/ha, output value by 1 798.05 yuan/ha, the rate of high-grade tobacco leaves by 3.93%, and soil pH from 5.05 to 5.36.
