生物有机肥对烤烟烟叶化学成分的影响

Effects of Biological Organic Fertilizer on Flue-cured Tobacco Chemical Composition

通过专用生物有机肥和饼肥联合使用的大田试验,研究了宛西烤烟烟叶化学成分。结果表明,增施生物有机肥能够显著提高土壤供应养分的能力。与常规施肥相比,增施生物有机肥处理的各部位烟叶还原糖、总糖和淀粉含量更接近于优质烟标准,各处理中下部烟叶还原糖与烟碱比更适宜,并且降低烟叶中全氮含量、烟碱含量和氯离子含量等,有效改善烟叶品质。

Through field experiment,special biological fertilizer combined with cake fertilizer were applied to tobacco,Wanxi flue-cured tobacco leaves chemical composition were researched.The results showed that increasing biological organic fertilizer can significantly improve soil nutrient supply ability,and compared with the conventional fertilizer,the contents of tobacco reducing sugar,total sugar and starch are more close to standard of high quality tobacco as biological organic fertilizer were applied,reducing sugar to nicotine ratio are more suitable in the middle part and underpart tobacco at all the special organic fertilizer treatments,the contents of tobacco total nitrogen,nicotine and chlorine ion were reduced,markedly improving the quality of tobacco.
