氨基酸肥对烤烟减肥增效的作用

目的]探究氨基酸肥对烤烟生长发育和烟叶品质的影响。方法]以云烟87为供试烤烟品种,采用同田对比的方式,设化学肥料(对照)、化学肥料+固态氨基酸肥、化学肥料+液态氨基酸肥3个处理,研究氨基酸肥对烤烟减肥增效的作用。结果]施用固态氨基酸肥烤烟的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;固态氨基酸肥处理的产量最高,而液态氨基酸肥处理的原烟外观质量最好,能提高均价和中上等烟比例,获得较好的经济效益。液态氨基酸肥处理的各部位烟叶糖碱比、双糖差均最适宜,化学成分协调性最好。与对照相比,氨基酸肥料处理的刺激性更小,余味更舒适,其中液态氨基酸肥处理的杂气较轻,感官质量整体表现最好。结论]综合比较,施用化学肥料+液态氨基酸肥有助于促进烤烟生长发育和提高烟叶品质。

Effects of Amino Acid Fertilizer on Flue-cured Tobacco Fertilizer Reducing and Efficiency Increasing

Objective] The aim was to explore effects of amino acid fertilizer on flue-cured tobacco growth, development and quality.Meth-od] With Yunyan87 as tested flue-cured tobacco varieties, by means of the same field contrast, setting up three treatments:chemical fertilizer (control), chemical fertilizer+solid amino acid, chemical fertilizer+liquid amino acid, effects of amino acid fertilizer on flue-cured tobacco fertilizer reducing and efficiency increasing were studied. Result] Applying solid amino acid fertilizer, agronomic traits, yield had best per-formance; while applying liquid amino acid fertilizer, top leaf opening, raw tobacco appearance quality, mean price, proportion of middle and high quality tobacco, economic benefits, ratio of sugar and nicotine in tobacco leaves, disaccharide difference, coordination of chemical com-position had good performance.Compared with the control, tobacco treated by amino acid fertilizer had less irritating and more comfortable taste; tobacco treated by liquid amino acid, miscellaneous gas was light, the overall performance of the sensory quality was best. Conclu-sion] Chemical fertilizer+liquid amino acids is conductive to promote the growth and development of flue-cured tobacco and improve the qual-ity of tobacco leaves.
