为探明氨基酸肥对烤烟生长发育和烟叶品质的影响,通过同田对比的方式,开展烤烟施用氨基酸肥减肥增效技术示范。结果表明:施用氨基酸肥料对烤烟大田生育期影响不大,但对烤烟的农艺性状、经济性状和烟叶品质都有一定的影响。施用固态氨基酸肥农艺性状整体表现最好,液态氨基酸肥有利于烟株顶部叶片的开片;施用固态氨基酸肥的处理亩产量最高,而施用液态氨基酸肥的处理,原烟外观质量最好,能提高均价和中上等烟比例,获得较好的经济效益。烟叶化学成分分析结果表明,施用氨基酸肥料的处理,总糖、还原糖含量适中,化学成分协调性好于对照,其中施用液态氨基酸肥的处理各部位烟叶糖碱比、双糖差均最适宜,化学成分协调性最好。中部烟叶感官质量评吸结果表明,与对照相比,施用氨基酸肥料的处理刺激性更小,余味更舒适,其中施用液态氨基酸肥的处理杂气较轻,感官质量整体表现最好。
In order to find out the effect of amino acid fertilizer on the growth and development of flue-cured tobacco and the quality of tobacco leaves, a demonstration of the application of amino acid fertilizer for reducing fat and improving efficiency of flue-cured tobacco was carried out by comparing with the same field. The results showed that the application of amino acid fertilizer had little effect on the growth of flue-cured tobacco in the field, but had some effects on the agronomic characters, economic traits and the quality of tobacco leaves. The application of solid amino acid fertilizer had the best performance of agronomic traits. The liquid amino acid fertilizer was beneficial to the opening of top leaf of tobacco plants. The treatment of solid amino acid fertilizer had the highest yield per mu, while the treatment of liquid amino acid fertilizer had the best appearance and quality Increase the average price and the proportion of upper-class tobacco, access to better economic benefits. Chemical analysis of tobacco leaves showed that the application of amino acid fertilizer treatment, total sugar, reducing sugar content is moderate, the chemical composition of coordination is better than the control, the application of liquid amino acid fertilizer treatment of various parts of tobacco leaf nicotine ratio, Chemical composition of the best coordination. Sensory evaluation of central tobacco leaves showed that compared with the control, the application of amino acid fertilizer was less irritating and the aftertaste was more comfortable. The application of liquid amino acid fertilizer was lighter and the organoleptic quality was the best.
