[目的]为探索沙壤土植烟地区较适宜的施肥方法。[方法]对云南省红河州建水县砂壤土的烤烟K326品种进行了不同有机无机配方施肥试验研究。[结果]有机肥的施用能够提高烟叶厚度、叶面密度和填充值,提升烟叶的外观品质,其中烟叶长度和油分提升尤为明显;有机肥有利于降低烟叶总氮和烟碱含量,提高钾元素和氯元素含量,使烟叶的化学成分更为协调;有机肥的施用在不同程度上提高了烟叶总糖、还原糖的含量,有利于提高烟叶内在品质;有机肥的施用提高了烟叶的感官品质,使得烟叶香气质柔和、细腻,烟气浓度高,口感纯净,刺激性小。[结论]有机无机配方施肥比例为85%复合肥与15%生物肥2号的配比最适于当地砂壤土生产优质烟叶。
[Objective] The purpose was to explore the suitable fertilization method in sandy loam tobacco planting areas. [Method] The experiment of different organic and inorganic formula fertilizers on flue-cured tobacco K326 in sandy loam soil of Jianshui County of Honghe Prefecture in Yunnan Province was conducted. [Result] The application of organic manure could increase the thickness of tobacco leaves, leaf surface density and filling value, and improve the appearance quality of tobacco leaves, especially the tobacco leaf length and oil content enhancement; Organic manure was beneficial to reduce the content of total nitrogen and nicotine, And chlorine content, so that the chemical composition of tobacco leaves more coordinated; the application of organic fertilizer to varying degrees, increase the total sugar, reducing sugar content, is conducive to improving the intrinsic quality of tobacco; organic fertilizer to improve the sensory quality of tobacco , Making the aroma of tobacco soft, delicate, high flue gas concentration, pure taste, irritation. [Conclusion] The ratio of organic and inorganic formula fertilizing 85% compound fertilizer and 15% biological fertilizer 2 was the most suitable for producing high quality leaf in the local sandy loam.
