摘要
为了减少烟草栽培中常规施肥用量,采用田间实验,通过逐渐加大施用特制的生物有机肥、增施麦秆还田并减少化学肥料的方法,对生物有机肥和麦秆还田在提高土壤供应养分的能力及烤烟烟叶品质的影响方面作了研究。研究表明:增施生物有机肥能够显著提高土壤供应养分的能力,激发土壤中氮素、磷素的释放。几种施肥方式对烟叶氮的影响不同。增施生物有机肥能增加烤烟烟叶中的钾含量,降低烟碱含量。增施生物有机肥和麦秆还田能使烟叶中氯含量减少。适当减少常规施肥量1/4~1/3既可降低成本,也有益于形成合适范围的烟叶品质成分。
Through field experiments, by applying bio-organic fertilizer and wheat straw, reducing chemical fertilizer, soil nutrition supplied capacity and tobacco quality were studied. The experimental results show that: Increasing bio-organic fertilizer can significantly increase the capacity of the soil nutrient supply, improved potassium content and depressd nitrogen, nicotine and chlorine ion content and other harmful factors in the flue-cured tobacco leaves, significantly improvement tobacco quality.
