为研究多孔土壤改良剂对毕节地区土壤性状及烤烟产量和品质的影响，分析比较不施改良剂（CK）、施用秸秆（T1）、T20 改良剂（T2）、70%T20 改良剂+30%竹炭（T3）四种处理对植烟土壤性状及烤烟产质的影响。结果表明，与对照相比，不同改良剂可使土壤 p H 提高 0.02~0.23 个单位，全氮、全磷、全钾含量分别提高 1.21%~7.27%、1.16%~8.14%和 0.83%~4.44%；土壤碱解氮、有效磷、速效钾分别提高3.39%~15.2%、10.8%~50.9%及 1.78%~37.0%。从生长特性看，T1、T2 及 T3 处理烤烟株高、茎围、有效叶数及叶面积均较 CK 有所增加。从产质量来看，改良剂处理烟叶产量较 CK 增产 3.6%~8.0%，烟叶产值增加 3 030~4 910 元 hm-2，上等烟叶比例提升 3.6%~11.7%；T1、T2 处理每千克烟叶均价提高了 1.8 元及 1.0元。所有处理的烤烟烟碱、全氮、还原糖、钾离子、氯离子均处于优质烟叶适宜范围，而施用改良剂的烟叶全氮、还原糖、钾离子含量均高于 CK 处理，添加土壤改良剂有助于改善烤烟氮碱比、糖碱比、糖氮比，使烤烟内在化学成分渐趋合理。总之，毕节烟区适当添加土壤改良剂能有效改善烟田土壤条件，提升烤烟产量和品质。
In order to study the effects of porous soil amendment on soil properties and yield and quality of tobacco in Bijie Prefecture, the effects of applying CK, Effect of Bamboo Charcoal (T3) Treatments on Soil Properties and Flue - cured Tobacco Quality. The results showed that compared with the control, different amendments could increase soil p H by 0.02-0.23 units, and the contents of total nitrogen, total phosphorus and total potassium increased by 1.21% -7.27%, 1.16% -8.14% and 0.83% -4.44, respectively %. Soil available nitrogen, available phosphorus and available potassium increased by 3.39% -15.2%, 10.8% -50.9% and 1.78% -37.0%, respectively. From the growth characteristics, T1, T2 and T3 treatment of flue-cured tobacco plant height, stem circumference, effective leaf number and leaf area were increased compared with CK. From the perspective of yield and quality, the yield of improved tobacco leaves was 3.6% -8.0% higher than that of CK, the output value of tobacco increased by 3030-4 910 yuan hm-2, and the proportion of fine tobacco increased by 3.6% -11.7%. Tobacco average price increased by 1.8 yuan and 1.0 yuan. All treatments of nicotine, total nitrogen, reducing sugar, potassium ion and chloride ion of flue-cured tobacco were in the proper range of good quality tobacco, while the contents of total nitrogen, reducing sugar and potassium in tobacco were all higher than that of CK, It helps to improve the ratio of nitrogen to nicotine, the ratio of sugar to nicotine and the ratio of sugar to nitrogen in flue-cured tobacco so that the chemical composition of flue-cured tobacco becomes more and more reasonable. In conclusion, the appropriate addition of soil conditioner in Bijie tobacco area can effectively improve the soil conditions in tobacco fields and enhance the yield and quality of tobacco.
