摘要
采用单因素随机区组实验设计,研究不同施肥处理对党参产量和次生代谢物合成积累量的影响,确定合理的施肥配比和采收期,为党参规范化栽培提供依据。试验结果显示,适量氮肥有利于党参根直径和根生物量的提高,磷肥可以促进党参多糖含量的增加,有机肥可以提高党参炔苷的含量。党参产量、多糖及醇溶性浸出物含量随着生长时间的延长而增加,党参炔苷含量随着生长时间的延长而减少。综合各因素分析,试验区党参的合理采收期应为10月下旬,施用有机肥对党参生物量和次生代谢物的积累最有利。
The research studies the effect of different fertilization treatments on yield and accumulation of secondary metabolites of Codonopsis pilosula by using single factor randomized block design, in order to ensure reasonable harvesting time and fertilization ratio, and provide the basis for standardized cultivation of C. pilosula. According to the clustering results, the nitrogen fertilizer benefitted for the improvement of root diameter and biomass of C. pilosula. The phosphate fertilizer could promote the content of C. pilosula polysac- charide. The organic fertilizers could increase the content of lobetyolin. With the time going on, C. pilosula＇s yield, polysaccharide and ehanol-soluble extracts increased while the content of lobetyolin decreased. According to various factors, October is a more reason- able harvest period. Organic fertilizers are more helpful to the yield and accumulation of secondary metabolites of C. pilosula.
