【摘要】 研究不同氨基酸有机肥对烤烟生长发育及产质量影响,为烤烟生产施肥提供参考依据。采用小区试验方式,对比常规生物有机肥(对照)、氨基酸有机肥A型150 kg/hm~2、氨基酸有机肥A型300 kg/hm~2、氨基酸有机肥B型150 kg/hm~2和氨基酸有机肥B型300 kg/hm~2与化肥配施对烟叶农艺性状、整齐度、根干重、经济性状、化学成分与评吸质量的影响。结果表明:氨基酸有机肥与生物有机肥相比,能提高上中等烟叶比例,提高中部叶的钾氯比与上部叶的总糖含量,降低上部叶的总氮含量,改善中部烟叶的香气质,增加中部烟叶的香气量,提高中部烟叶的评吸质量。4个氨基酸有机肥处理间相比,以300 kg/hm~2用量的氨基酸有机肥A型较好,能促进大田烤烟个体与群体的中部叶生长发育,促进烟草根系的发育,提高烟叶产量与产值,增加烟农收入,总体上化学成分较协调,中部叶评吸质量较好。湘西植烟区烟叶生产以氨基酸有机肥A型300 kg/hm~2较适宜。更多还原

【Abstract】 The purpose of this experiment is to clarify the effects of different types and rates of amino acidorganic fertilizers combined with chemical fertilizers on growth and development and yield and quality of flue-cured tobacco leaves, and provide a reference for the production practice. A field plot experiment wasconducted to investigate the agronomical characteristics, unifornity, root dry weight, value and output,chemical components and mid leaves smoking quality of flue-cured tobacco leaves under the treatments of bio-mixed organic fertilizer(control), and amino acid organic fertilizer A 150 kg/hm~2, amino acid organic fertilizer A 300 kg/hm~2, amino acid organic fertilizer B 150 kg/hm~2, amino acid organic fertilizer B 300 kg/hm~2 in combination with chemical fertilizers. The results indicated that under the amino acid organic fertilizertreatment, the proportion of mid high grade leaves, the potassium to chlorine ratio of the mid leaves, and thecontent of total sugar of upper leaves and smoking quality of mid leaves increased compared with those underbio-organic fertilizer treatment, improving the fragrance quality and increasing the fragrance amount of midleaves. The contents of TN in upper leaves decreased in the four amino acid organic fertilizer treatments. Highquality leaves containing coordinated chemical compositions could be obtained by the amino acid organicfertilizer A 300 kg/hm~2, which could also improve the flavor quality of mid leaves, promote tobacco growth anddevelopment, enhance good root system development, increase tobacco yield and quality and farmers’ income.So the amino acid organic fertilizer A 300 kg/hm~2 is the optimum for tobacco-growing region of Xiangxi.更多还原
