不同烟秆生物炭用量对烤烟生长及产质量的影响

Effects of Different Amount of Tobacco Stem Biochar on Growth,Production and Quality of Flue-cured Tobacco

[目的]研究烟秆生物炭不同施用量对烤烟生长及产质量的影响。[方法]施用不同用量的烟秆生物炭,对烤烟大田生育期、农艺性状、抗病性、经济性状、烟叶外感质量进行分析。[结果]烟秆生物炭不同用量对烤烟大田生育期、烟叶产量、质量、外感质量影响较大,以施用生物炭5025 kg/hm^(2)烤烟农艺性状、经济性状和烟叶外观质量最优。[结论]该研究可为贵州省在烤烟生产上推广应用烟秆生物炭提供理论依据。

[Objective]To study the effects of different amounts of tobacco stalk biochar application rates on flue-cured tobacco.[Method]Different amounts of tobacco stalk biochar was applied to analyze the field growth period,agronomic characters,disease resistance,economic characters and exogenous quality of flue-cured tobacco.[Result]Different amounts of tobacco stalk biochar had a greater impact on the growth period,tobacco leaf yield,quality,and exterior quality of flue-cured tobacco.The application of biochar 5025 kg/hm^(2) of flue-cured tobacco had the best agronomic,economic and appearance quality.[Conclusion]This study can provide a theoretical basis for the promotion and application of tobacco stalk biochar in the production of flue-cured tobacco in Guizhou.
