摘要
[目的]为腐殖酸在烤烟上大面积应用提供依据。[方法]采用多点大区对比方法,研究了河南烤烟上施腐殖酸225 kg/hm^2对烟叶产量和品质的影响。[结果]施腐殖酸的临颖和罗山两点株高及叶面积显著高于对照,方城点表现出一定优势,株高和叶片数分别比对照增加2.4-6.0 cm和0.1-1.3片。与对照相比,施腐殖酸的3点都增产,平均增产12.7%,产值平均增加1 666.5元/hm^2。施腐殖酸处理与对照相比,均价相差不大,上、中等烟比例临颖和方城点高于对照,罗山点低于对照,烟叶总糖含量降低,蛋白质和烟碱含量略有提高,中部叶钾含量提高,钾氯比提高。[结论]腐殖酸肥能促进烤烟植株发育,利于烟叶正常落黄,提高烟叶产量,改善烟叶品质,使烟碱等内含物质更加协调。
[Objective]The aim was to provide basis for the application of humic acid in flue-cured tobacco in large area.[Method] The influences of fertilizing humic acid at 225 kg/hm2 in the flue-cured tobacco on the yield and quality of tobacco leaf in Henan were studied by the comparative method in multi-site tests.[Result] The plant height and leaf area of flue-cured tobacco in the 2 sites of Linying county and Luoshan county where the humic acid was fertilized were significantly higher than that of CK,and that in the site of Fangcheng county showed some dominance.The plant height and leaf number increased by 2.4～6.0 cm and 0.1～1.3 than CK respctively.Compared with CK,the tobacco yield in 3 sites fertilized humic acid all increased,averagely by 12.7% and the yield value averagely increased 1 666.5 yuan/hm2.Compared with CK,there was no great difference on the average price of flue-cured tobacco,and the proportions of superior and middle tobacco in the sites of Linying county and Fangcheng county were higher than that of CK,that of Luoshan county was lower than that of CK;the total sugar content in tobacco leaf decreased,protein and nicotine contents had some increment,the potassium content in the leaf from middle part was increased,and the ratio of potassium to chlorine was increased.[Conclusion] The humic acid fertilizer can promote the development of tobacco plant,help to yellowing of tobacco leaf,enhance tobacco yield,improve tobacco quality and have the internal substance such as nicotine be more harmonious.
