To investigate the effects of different ratios of organic and chemical fertilizers on the yield and quality of Epimedium pubescens,so as to provide a scientific basis for the fertilization of high-yield and high-quality E. pubescens cultivation. In this experiment,a field plot test was conducted,and CK(without fertilizer) was set as the control group,with five treatment groups with different ratios of organic fertilizers and chemical fertilizers set up,namely OF0(100% chemical fertilizers),OF25(25% organic fertilizers),OF50(50% organic fertilizers),OF75(75% organic fertilizers),and OF100(100% organic fertilizers). The effects of different fertilization patterns on the agronomic traits,yield,effective component content,nutrient accumulation,and soil physicochemical properties of E. pubescens were determined,and the yield and quality of the medicinal herb were comprehensively evaluated by using the CRITIC weights method. It was found that the herb yield of each treatment group was significantly increased compared with the CK group,although the yield of the groups with both organic fertilizer and chemical fertilizer was slightly lower than that of OF0. However,there was no significant difference,which indicated that the organic fertilizer combined with chemical fertilizer could ensure the herb yield. With the increase in organic fertilizer ratios,the medicinal components epimedin A,epimedin B,and epimedin C showed a tendency of first increasing and then decreasing,with the highest content in the OF25,while icariin showed a rising trend,with the best in the OF100. However,overall,the total flavonol glycosides ABCI accumulated the most in the OF25. The results of the CRITIC method showed that the top three fertilization treatments in terms of the comprehensive scores of the medicinal herb were OF25,OF50,and OF75. Organic fertilizer combined with chemical fertilizer is conducive to improving the soil's fertilizer holding and supply capacity,and the soil indexes are optimal in OF100. The soil enzyme activity is the highest in OF75. Meanwhile,organic fertilizer combined with chemical fertilizer can help the plant's uptake and accumulation of nutrients,and OF25 shows the most obvious effect.By comprehensively considering the influence of different ratios of organic and chemical fertilizers on the yield,effective component content,nutrient accumulation,and other indexes of E. pubescens,it is recommended that a 25% ratio(7 500 kg·hm~(-2)) of organic fertilizers and chemical fertilizers should be used in E. pubescens production in the first year,so as to promote the E. pubescens industry to increase yield and improve quality.
为探究不同有机肥料与化学肥料配比对毛茛科淫羊藿产量和品质的影响，为高产优质淫羊藿栽培施肥提供科学依据。本试验采用田间小区试验，以不施肥的CK为对照组，设置5个不同有机肥料与化学肥料配比的处理组，分别为OF0（100%化学肥料）、OF25（25%有机肥料）、OF50（50%有机肥料）、OF75（75%有机肥料）和OF100（100%有机肥料）。测定不同施肥模式对淫羊藿农艺性状、产量、有效成分含量、养分积累及土壤理化性质的影响，并采用CRITIC权重法对药材产量和品质进行综合评价。结果表明，各处理组药材产量均显著高于CK组，虽然有机肥与化肥配施组的产量略低于OF0，但差异不显著，说明有机肥与化肥配施能保证药材产量。随着有机肥比例的增加，淫羊藿苷A、淫羊藿苷B和淫羊藿苷C呈先增加后降低趋势，OF25含量最高，而淫羊藿苷呈上升趋势，OF100最佳。但总体而言，总黄酮醇苷ABCI在OF25中积累最多。CRITIC法结果显示，药材综合评分排名前三的施肥处理为OF25、OF50和OF75。有机肥与化肥配施有利于提高土壤保肥供肥能力，OF100土壤指标最优，OF75土壤酶活性最高。同时，有机肥与化肥配施有助于植株对养分的吸收和积累，OF25效果最明显。综合考虑不同有机肥料与化学肥料配比对淫羊藿产量、有效成分含量、养分积累等指标的影响，建议淫羊藿生产第一年有机肥料与化学肥料按25%比例（7 500 kg·hm~(-2)）施用，以促进淫羊藿产业增产提质。
