| 摘 要： | 目的]对烤烟的耐肥性进行综合评价并筛选鉴定指标。方法]在2种施肥水平下,对6个烤烟品种测定了株高、茎围、节距、叶总数、有效叶数、叶面积、产量、上等烟比例、均价、产值等10项与施肥量有关的指标,并用主成分和逐步回归方法进行分析。结果]烤烟打顶后采摘前的茎围、节距、有效叶数、叶面积及产值与耐肥性(对肥料的敏感性)有显著关系,可作为烤烟耐肥性的鉴定指标。其预测结果与田间表现基本一致。结论]用该方法对烤烟耐肥性进行综合评价是可行的。

Comprehensive Evaluation of Fertilizer Tolerance of Flue-cured Tobacco and Screening of the Identification Indexes |

| Abstract: | Objective] To comprehensively evaluate the fertilizer tolerance of flue-cured tobacco and to screen the identification indexes.Method] Under two different fertilization levels,ten indexes of six tobacco varieties were measured,including plant height,stem diameter,pitch,leaf number,effective leaf number,lea area,yield,superior tobacco ratio,average price and output value.Principal component analysis and stepwise regression analysis were used.Result] After topping and before harvesting,the stem diameter,effective leaf number,leaf area and output value of flue-cured tobacco had significant correlation with fertilizer tolerance,which could be used as the identification indexes.The results of field performance and were basically the same as the predicting results.Conclusion] This method was feasible for the comprehensive evaluation of tobacco fertilizer tolerance. |
