摘　　要：通过向土壤加入不同种类(海泡石、膨润土、硅藻土、汉白玉)土壤改良剂与不加土壤改良剂种植的烤烟对比来对烤烟提质增效效应进行探究。结果表明,4种土壤改良剂对于烟叶大田生育期时间的长短无明显影响;从农艺性状来看,使用海泡石处理的烤烟普遍长势要比其他处理好;各处理主要的病情是气候斑点病、赤星病和烟草花叶病,且发病率接近;各处理的产值、产量不同,施用硅藻土处理的产值超过对照9832.65元/hm^2,上等烟比例最高的是施用海泡石的处理;施用汉白玉和海泡石处理的化学成分含量更接近优质烟叶的化学成分含量,烟叶品质最佳。由此可得,在植烟土壤中施用2 kg/m^2的海泡石,可以有效改善烟株的植物学性状以及烟叶化学品质,同时产值和产量也高于对照组。The effects of improving quality and efficiency of flue-cured tobacco were studied by adding different kinds of soil amend⁃ments(sepiolite,bentonite,diatomite,white marble)and lue-cured tobacco planted without soil modifiers.The results showed that the four soil modifiers had no significant effect on the growth period of tobacco leaves in field.In terms of agronomic characters,the growth of flue-cured tobacco treated with sepiolite was generally better than that of other treatments.The main diseases were climate spot weather fleck disease,brown spot disease and tobacco mosaic disease,and the incidence rate was close.The output value and yield of each treatment were different.The output value of diatomite treatment was higher than that of the control group by 9832.65 yu⁃an per hectare.The highest proportion of superior tobacco leaves was the treatment with sepiolite.The contents of chemical components treated with white marble and sepiolite were closer to that of high-quality tobacco leaves,and the tobacco quality was the best.There⁃fore,the application of sepiolite of 2 kg/m^2 in the tobacco planting soil can effectively improve the botanical characters of tobacco plants and the chemical quality of tobacco leaves,and the output value is also higher than that of the control group.
