摘要
通过"3414"田间试验,研究了不同肥料配方对烤烟生长发育、产量及质量的影响。结果表明:氮肥用量最多的处理(N3P2K2)的烟株在生长后期长势最好,烤后烟叶总糖和还原糖含量最低,总氮含量较高,但其烤后烟叶的经济性状没有表现出最好的优势;在14个处理中,以处理N2P2K2(施用N 9.00 kg/667 m2、P2O59.00 kg/667 m2、K2O 22.50 kg/667 m2)的烤烟的产值最高,经济效益最好。
The influences of different fertilizer formulas on the growth, development, yield and quality of flue - cured tobacco were studied through ＂3414＂ field test. The results indicated that： in the treatment N3P2K2 （applying the most nitrogen） , the to- bacco plants had the best growth vigor at late growth stage, the content of total sugar and reducing sugar in baked tobacco teaves was the lowest, and the content of total nitrogen was higher, but the economic characters of flue - cured tobacco leaves did not show the best advantage. Among 14 treatments, the treatment N2P2K2 （ applying N 9.00 kg/667 m2, P205 9.00 kg/667 m2, K20 22.50 kg/ 667 m2 ） obtained the highest outout value and the best economic benefit of flue - cured tobacco oroduction.
