土壤有益微生物扩繁剂对烤烟生长及产质量的影响

Effects of profitable soil microorganism propagation agent on the growth yield and quality of tobacco

摘要: 为进一步了解土壤有益微生物田间扩繁剂纳米酵豆对烤烟生长的影响，进行了不同肥料用量与纳米酵豆混合施用试验。结果表明，常规生产肥料用量的70% 与纳米酵豆混匀施用，能促进烤烟早发快长，其中团棵期、现蕾期、平顶期株高比常规施肥对照分别提高21.5%、11.7% 和7.4%，腰叶面积分别提高20.7%、1.3% 和6.5%，对其他农艺性状影响不显著；纳米酵豆处理可提高烤烟抗病性，但对原烟外观质量影响不大；纳米酵豆处理能改善烟叶等级结构，提高烟叶钾含量，烟叶产值比对照提高14.6%。

Abstract: To research effect of profitable soil microorganism on the growth of tobacco，different fertilizer amount mixed with profitable soil microorganism propagation agent was applied in the production of tobacco. The results showed that 70% amounts of normal fertilizer mixed with profitable soil microorganism propagation agent can promote the growth of tobacco distinctly compared with control group. Compared with CK，the stem height was increased respectively by 21.5%，11.7%，7.4%，and the middle leaf area was increased respectively by 20.7%，1.3%，6.5% in rosette stage，bud stage and topping stage. T3 can improved the quality and potassium content of tobacco leaves，and the market value was improved by 14.6% compared with CK.
