摘　　要：以箭叶淫羊藿种子移栽苗为试材,采用不同用量有机底肥、不同株距、不同密度遮阳网、不同施加量复合肥(N∶P∶K=12∶20∶13)组成四因素三水平的正交栽培条件,统计各小区成活率、产量,测定折干率、浸出物、总灰分以及总黄酮、朝藿定A、朝藿定B、朝藿定C及淫羊藿苷含量,采用主成分分析法综合评价,研究了箭叶淫羊藿种子移栽苗在不同栽培条件下的成活率、产量及质量变化,以期为箭叶淫羊藿栽培技术规范的制定提供参考依据。结果表明:40 g·m^(-2)的复合肥,75%的遮阳网,4.5 kg·m^(-2)的有机肥,株距为20 cm为最佳组合,其成活率为63.23%,产量为32.5 g·m^(-2),总黄酮、淫羊藿苷、朝藿定A、B、C含量分别为9.35%、3.01%、0.20%、0.20%、9.09%。说明箭叶淫羊藿种苗移栽时应选择遮阴度高、株距较小、有机肥料较多量施加的栽培条件,该移栽条件下箭叶淫羊藿成活率较高,产量较高,质量较优异。Taking the transplanted seedlings of Epimedium sagittatum as test materials,orthogonal cultivation conditions with different amounts of organic base fertilizer,different plant spacing,different densities of shading nets and different application amounts of compound fertilizer(N∶P∶K=12∶20∶13)were used to make statistics on the survival rate and yield of each plot,and to determine the dry weight,extract,total ash,total flavonoids,epimedin A,epimedin B,epimedin C and icariin contents of each plot.And the principal component analysis method was used for comprehensive evaluation.The changes of survival rate,yield and quality of transplanted seedlings of Epimedium sagittatum under different cultivation conditions were studied,in order to provide reference for the standarch of cultivation techniques.The results showed that 40 g·m^(-2)compound fertilizer,75%shading net,4.5 kg·m^(-2)organic fertilizer and 20 cm plant spacing were the best combination,and the survival rate was 63.23%,the yield was 32.5 g·m^(-2),and the contents of total flavonoids,icariin,epimedin A,B and C were 9.35%,3.01%and 0.20%,0.20%,9.09%,respectively.It showed that the cultivation conditions of high shade,small plant spacing and large amount of organic fertilizer should be selected when transplanting Epimedium sagittatum seedlings.Under this transplanting condition,Epimedium sagittatum had high survival rate,high yield and excellent quality.
