| 摘 要： | 以东北填充型烤烟品种"龙江911"为试验材料,通过正交回归田间试验,建立了氮、磷、钾肥与烤烟上部叶片烟碱含量的回归效应模型,并对各因子和交互作用进行了分析,模拟计算得出以降低上部叶片烟碱含量为目标的优化施肥方案.对模型解析表明,随施氮量增加,上部叶片烟碱含量呈先上升后下降趋势;随施磷量增加,烟碱含量呈上升趋势;随施钾量增加,烟碱含量呈急剧下降趋势.双因素效应大小依次为:氮钾＞磷钾＞氮磷,在一定范围内,氮磷、磷钾与烟碱含量表现为负相关,存在拮抗作用;而氮钾则相反,存在促进作用.对氮、磷、钾肥与烤烟上部叶片烟碱含量模型的综合分析得出:在植烟土壤为河淤土的生产区,烟田的基础施肥量建议为:氮肥33.5～47.8kg·hm-2,磷肥40.2～63.6 kg·hm-2,钾肥78.0～119.6kg·hm-2.

| Abstract: | An orthogonal regression field experiment was conducted to study the effects of combined fertilization of N,P,and K on the nicotine content in the upper leaves of filling type flue-cured tobacco(Nicotiana tobacum) varietyLongjiang 911from Northeast China.The regression effect models of N,P,and K fertilization rates and upper leaf nicotine content were established,and the effects of the fertilization rates and their interactions were analyzed.Based on these,an optimized NPK fertilization scheme was drawn up ... |
