| 摘 要： | 针对不同施肥种类、种植密度、采收期3个因素,通过单因素试验研究了它们对川芎中多糖含量的影响,使用正交试验设计研究了各因素间的相互作用并优选出最佳组合。结果表明：不同施肥种类、种植密度、采收期对川芎多糖含量存在显著影响,当每亩施用复合肥40kg,种植行距为30cm,窝距为20cm,翌年7月20日采收时,川芎中多糖含量最高。各因素中,施肥种类对多糖含量影响最大,其次为种植密度,采收期对多糖含量的影响最小。

| Abstract: | Using a three-factor experiment,the effect of different fertilizers,planting densities and harvest time on the Polysaccharide content in ligusticum chuanxiong Hort.had been determined in the current work.The interaction within factors had been investigated and the best combination of factors had been selected by orthogonal design.Result showed that those factors had significant effect on Polysaccharide content in ligusticum chuanxiong Hort.Supplied with compound fertilizer,the density of 20cm×30cm gave the highest Polysaccharide content harvested on 20th July of next year after planting.Therefore,the best factor affecting Polysaccharide content in ligusticum chuanxiong Hort is fertilizer,followed by planting density and harvest time. |
