药用菊花不同繁殖方法的产量比较及其构成因子研究

Medicinal Chrysanthemum morifolium Yield Comparison of Different Reproduction Methods and Study on the Component Factors of Yield

目的比较药用菊花不同繁殖方法对其产量的影响,并分析对植株产量具有显著影响的植物性状,以期为药用菊花栽培过程中采用合适的繁殖方法和田间管理措施提供理论依据。方法采用随机区组田间试验设计,结合方差分析和回归分析,对药用菊花不同繁殖方法的产量和主要植物性状进行比较分析。结果采取扦插繁殖的植株产量明显高于分株繁殖,差异达极显著水平;植株头状花序的数量是构成其产量的主要因素(r=0.933),其次为植株总分枝数(r=0.819)。结论药用菊花栽培过程中,采用扦插繁殖法,并通过适时打顶促进植株分枝的措施,能有效提高其产量。

Objective Comparison the yield of medicinal Chrysanthemum morifolium which reproduced by different methods, and analyzed the plant characters which had a significant effect on plant production, in order to provide theoretical basis for suitable re- production methods and field management measures in cultivation process of medicinal Chrysanthemum morifolium. Method- s Used randomized block design in the field experiment, and combined with variance analysis and regression analysis, comparative analysis the yield by different propagation methods and main traits of medicinal Chrysanthemum morifolium. Results The plant yield of cutting propagation was significantly higher than the division propagation, the difference reached extremely significant level; the capitulumg number was the main factors that constituted the production （r = 0. 933 ） ,followed by the plant total number of branches （r = 0.819）. Conclusion In the cultivation process of medicinal Chrysanthemum morifolium, used cutting propagation and through timely topping measures to promote plant branches could extremely effectively increased yield.
