摘要
为了探讨生物有机肥对烤烟抗病性、产量产值及烟叶内在品质的影响,在四川省9个县(市)开展了田间试验。试验结果表明,生物有机肥可促进烟株生长发育,促进烟叶落黄成熟,提高单位面积产量、产值,并提高烟草对主要病害的抗性。施用生物有机肥的烟叶还原糖、总糖含量稍有降低,总植物碱含量升高,糖碱比、氮碱比明显减小,更加接近优质烟叶常规化学成分协调性要求;施用生物有机肥的烟叶感官评吸总得分明显提高。施用微生物有机肥既能减少化学肥料的施用量,又能促进烟株生长发育,提高烟株抗病性以及烟叶产质量。
In order to study the effects of CM-microbial organic fertilizer on tobacco disease resistance,yield and inner quality of tobacco leaf,we carried out field experiments in Sichuan Province.The results showed that：by the application of CM-microbial organic fertilizer,the growth and quality of tobacco were improved,yield per unit and mass area ratio were increased,the incidence of diseases was decreased,the contents of total sugar and reducing sugar were slightly reduced and the contents of total alkaloid,sugar-nicotine ratio,the ratio of nitrogen to nicotine were obviously lowered,closer to the coordination requirements for routine chemical compositions of flue-cured tobacco,and smoking quality was also improved.When CM-microbial organic fertilizer was applied in soil,the growth,disease resistance,yield per unit,mass area ratio and inner quality of flue-cured tobacco were improved,at the same time chemical fertilizers application was reduced.
