| 摘 要： | 为防止过量施肥导致环境污染及烟叶品质下降,通过大田试验,建立了氮磷钾肥与烤烟产量及烟叶主要化学成分的偏最小二乘回归施肥模型。结果表明,氮磷钾肥与烤烟产量及烟叶化学成分均有显著的回归关系,一次项系数表明了氮磷钾肥对烤烟影响的主次关系;交互项和二次项系数表明了氮磷钾肥的施用比例存在一定的临界值,氮磷钾肥在临界值内表现为协同促进的作用,高于临界值则表现为拮抗作用。若以获得最大经济效益为目的,最佳氮磷钾比例为1:1.6:2.1;若以改善烤烟烟叶香气、燃烧性及吸烟的安全性为目的,最佳氮磷钾比例为1:1.3:2.9。

| Abstract: | This study was conducted to provide a quantitative fertilization model for producing high quality filling flue-cured tobacco leaves and reducing environmental pollution and the quality decline of tobacco leaf problem resulted from over-fertilization.A mathematic model for the relations of flue-cured tobacco production and principal chemical components was established by the Partial Least-squares Regression(PLSR) fertilization function model through massive field experiments.The results showed that there was... |
