【摘要】 [目的]研究密度和基肥对长喙乌头产量和块根重的影响，确定适宜的栽培密度、基肥施用类型和用量。[方法]采用正交设计L₁₆（4⁴）,研究不同密度（A）和基肥（复合肥B、有机肥C、生物菌肥D）处理对长喙乌头产量、块根繁殖倍数、块根重的影响。[结果]不同因素对长喙乌头产量、块根繁殖倍数和块根重影响的方差分析表明，4个因素对长喙乌头产量均有极显著影响，影响大小依次为A>C>B>D,适宜的水平都能促进产量的提升；因素A对块根繁殖倍数有极显著影响，密度过高时，块根繁殖倍数下降，因素C对块根繁殖倍数有显著影响，施用有机肥可增加长喙乌头块根繁殖倍数；A、B、C对块根重有极显著影响，块根重随着密度增加而降低，适宜有机肥、复合肥可提高长喙乌头块根重。[结论]长喙乌头种植最佳处理组合为密度15 cm×15 cm,施复合肥450 kg/hm²、有机肥45 000 kg/hm²、生物菌肥180 kg/hm²。更多还原

【Abstract】 [Objective] In order to study the effects of density and base fertilizer on the yield and tuber weight of Aconitum georgei Comber.,the appropriate cultivation density, application type and dosage of base fertilizer were determined. [Method] Orthogonal design L₁₆（4⁴） was used to study the effects of different density（A） and base fertilizer（compound fertilizer B,organic fertilizer C,biological fertilizer D） on the yield, root multiplication ratio and tuber weight of A. georgei. [Result] Analysis of variance（ANOVA） on the effects of different factors showed that all four factors had a highly significant influence on the yield of A. georgei.The order of their impact magnitude was A>C>B>D,suitable levels of each factor promoted yield increase; factor A（density） had a highly significant influence on the tuber propagation coefficient, excessive density led to a decrease in the tuber propagation coefficient, factor C（organic fertilizer） had a significant influence, applying organic fertilizer increased the tuber propagation coefficient; factors A,B and C had a highly significant influence on tuber weight, tuber weight decreased with increasing planting density, suitable application of organic fertilizer and compound fertilizer increased the tuber weight of A. georgei.[Conclusion] The optimal treatment combination was 15 cm×15 cm, 450 kg/hm² of compound fertilizer, 45,000 kg/hm² of organic fertilizer and 180 kg/hm² of biological fertilizer.更多还原
