摘　　要：为研究氮、磷、钾配方施肥对接骨木果实产量的影响,采用“3414”完全施肥方案开展田间小区试验,测定不同配比施肥处理下接骨木的果实产量。结果表明,氮磷钾的合理配施能不同程度提高接骨木果实产量,其中N_(2)P_(2)K_(2)施肥处理下的产量最高,单株产量达2.63 kg。氮、磷、钾3种元素对接骨木产量存在明显的互作效应,表现为氮钾>磷钾>氮磷。全肥区的施肥依存度为44.9%,缺钾区施肥依存度为33.78%,说明钾肥对接骨木果实产量有着重要影响。本研究结果为指导和规范接骨木的施肥技术提供了理论依据。To study the effect of nitrogen,phosphorus,and potassium fertilization on the fruit yield of Sambucus williamsi Hance,a field trial was conducted using the"3414"complete fertilization scheme to determine the fruit yield of Sambucus williamsi Hance under different fertilization ratios.The results showed that a reasonable combination of nitrogen,phosphorus,and potassium could improve the fruit yield of Sambucus williamsi Hance to varying degrees,with the highest yield under N_(2)P_(2)K_(2) fertilization treatment,reaching 2.63 kg per plant.There is a significant interaction effect of nitrogen,phosphorus,and potassium on the yield of Sambucus williamsi Hance,manifested as nitrogen and potassium>phosphorus and potassium>nitrogen and phosphorus.The fertilization dependency in the fully fertilized area is 44.9%,and the fertilization dependency in the potassium deficient area is 33.78%,indicating that potassium fertilizer has an important impact on the yield of Sambucus williamsi Hance fruit.The results of this study provide a theoretical basis for guiding and standardizing the fertilization.
