摘　　要：施肥是促进林木生长,提高其产量和质量的重要技术措施。为了了解肥料对日本斤柿幼树营养生长的影响规律,采用3因素3水平的正交设计及10种处理,进行了配方施肥试验。结果表明:施肥对日本斤柿幼树的营养生长具有显著的促进作用,与对照树(未施肥)相比,施肥后试验树的树高、地径增长量、冠幅、发枝数、叶面积分别提高了27.6%、17.1%、54.0%、60.0%2、3.3%;不同施肥处理对日本斤柿幼树营养生长的影响也不同,其中以施用N3P3K1组合配方肥料的效果为最佳。Fertilization is an important technical measure for promoting growth and improving yield and quality of forest trees.In order to probe into the influencing law of fertilization on young Japan Jin Persimmon,formula fertilization test was carried out by orthogonal design.The results indicated that fertilization could remarkably promote vegetative growth of young Japan Jin Persimmon.Compared with the unfertilized trees,height,ground diameter,crown width,shoot number and leaf area of the fertilized trees were improved 27.6%,17.1%,54.0%,60.0% and 23.3%,respectively.Effects of different fertilization treatments on vegetative growth of young Japan Jin Persimmon were different,and the treatment with N3P3K1 combination had the best effect.
