对红壤中施入甘蔗渣、煤炭灰、大田营养土及三者混合物后烤烟的植物学性状、产量、质量进行了观察和研究．结果表明：加入甘蔗渣的处理比其它处理的烟株在生长早期发棵快、植株健壮，烟叶的产量较高，达２５５０３ｋｇ／ｈｍ２，比对照增产６３２％，烟株抗花叶病能力增强，烟叶糖分、施木克值、糖碱比高，烟碱含量降低，并且施入甘蔗渣能增加土壤中速效Ｋ，速效Ｐ，交换性Ｃａ，Ｍｇ等养分的含量；煤炭灰处理和大田营养土处理对烟株的生长、烟叶的产量无明显影响，但能提高烟株对花叶病的抵抗力，增加土壤速效Ｋ，速效Ｐ，交换性Ｃａ，Ｍｇ的含量和提高土壤ｐＨ值；混合材料处理的效果次于甘蔗渣处理．
The botanical characters, yield and quality of flue-cured tobacco after applying sugar cane bagasse, coal ash, nutrient soil in the field and mixtures of the three were observed and studied. The results showed that the treatment of adding sugar cane bagasse was faster than other treatments in the early growth stage, and the plant was robust. The yield of tobacco was 25503 kg / hm2, 632% higher than that of the control. Increased disease ability, sugar content of tobacco, application of mk value, high ratio of sugar and alkali and lower content of nicotine, and the application of bagasse increased soil available K, available P, exchangeable Ca, Mg and other nutrients; coal ash treatment And field nutrition soil treatment had no significant effect on the growth of tobacco plants and the yield of tobacco leaves but increased the resistance of tobacco plants to mosaic disease and increased the contents of soil available K, available P, exchangeable Ca, Mg and soil pH Value; mixed material treatment is inferior to bagasse treatment.
