绿肥翻压和菌剂配施对烤烟生长与产质量的影响

Effects of Overturning Pressure of Green Manure and Microbial Agents on Growth,Yield and Quality of Flue-cured Tobacco

以绿肥作物油菜为试验材料,设置常规施肥(CK)、常规施肥+哈茨木霉菌剂(T_(1))、常规施肥+胶质芽孢杆菌(T_(2))、常规施肥减量20%+绿肥翻压(T_(3))、常规施肥减量20%+绿肥翻压+哈茨木霉菌肥(T_(4))、常规施肥减量20%+绿肥翻压+胶质芽孢杆菌肥(T_(5))共6个处理,分析了油菜翻压与不同菌剂配施对烤烟生长及产质量的影响,结果表明:绿肥与菌剂配施能显著提高烟株前期大田长势和烤后烟叶的钾含量,以及显著降低烟叶的淀粉含量,优化钾氯比;能提高烟叶产量和产值,其中以T_(5)处理的效果最佳。

The green manure crop rape was taken as the research object,and the conventional fertilization(CK),conventional fertilization+Trichoderma harzianum(T_(1)),conventional fertilization+Bacillus mucilaginosus(T_(2)),conventional fertilization reduction of 20%+green manure overpressure(T_(3)),conventional fertilization reduction of 20%+green fertilizer overpressure+Trichoderma harzianum(T_(4))and conventional fertilization reduction of 20%+green fertilizer overpressure+Bacillus mucilaginosus(T_(5))were set.The effects of overpressure of rape combined with different bacterial agents on growth,yield and quality of flue-cured tobacco were studied.The results showed that the combined application of green fertilizer and bacterial agents could significantly improve the field growth of tobacco plants in early stage and the potassium content,and could significantly decrease starch content of tobacco.The ratio of potassium to chlorine was optimized.T_(5) treatment had the best effect.
