摘　　要：基于国内油橄榄重要产区广元油橄榄种植较普遍存在的施肥粗放、产量较低的问题,结合叶片营养元素分析技术,设计6种施肥配方(N、P、K、Ca、Mg、B),探究其对油橄榄生长发育及产量的影响。结果表明:D组施肥配方(N∶P∶K=6∶2∶3)显著促进新梢生长(长度增加23.5%,较对照,下同)、提高光合效率(叶绿素总量提升16.4%)、提升果实品质(含油率提高1.8%),研究为以广元为代表的四川东北部油橄榄产区提供了低成本、高效益的精准施肥方案,具有重要应用价值。This study addressed the prevalent issues of extensive fertilization practices and low yield in olive cultivation in Guangyuan City,a key olive-producing region in China.By integrating leaf element analysis technology,six fertilization formulas(N,P,K,Ca,Mg,B)were designed to investigate their effects on the growth,development,and yield of olive trees.The results demonstrated that the Group D fertilization formula(N:P:K=6:2:3)significantly enhanced new shoot growth(23.5%increase in length compared to the control),improved the photosynthetic efficiency(16.4%increase in total chlorophyll content),and elevated the fruit quality(1.8%increase in oil content).This research provided a low-cost,high-efficiency and accurate fertilization scheme for olive-producing areas in northeastern Sichuan Province,represented by Guangyuan City,and offered significant practical values for sustainable olive cultivation.
