摘　　要：[目的]探讨林下套种和不同施肥处理对油茶幼林生长的影响。[方法]以3年生"长林4号"油茶幼林作为试验林,对比6个施肥处理和生姜、花生、红薯及大豆等4种套种模式对油茶幼林生长的影响。[结果]套种大豆能明显促进油茶幼林株高和地径增长,套种花生有利于新梢生长,套种大豆的单株产果量最大(3.46 kg); T1处理(N1P1K1)的油茶幼林株高、地径和新梢长度最大,T3处理(N1P1K2)则是单株产果量最大,适当增施钾肥有利于提高油茶结果量。[结论]该研究可为油茶幼林生产提供借鉴。[Objective]To explore the effects of interplanting and different fertilization treatments on the growth of Camellia oleifera young forest.[Method]A 3-year-old“Changlin 4”C.oleifera young forest was used as an experimental forest,the effects of six fertilization treatments and four interplanting patterns of ginger,peanut,sweet potato and soybean on the growth of young C.oleifera forest were compared.[Result]Interplanting soybean could obviously promote the growth of plant height and ground diameter of young C.oleifera forest,and interplanting peanut was beneficial to the growth of new shoots.The yield per plant of interplanting soybean was the highest(3.46 kg);the height,ground diameter and shoot length of young C.oleifera forest were the highest under T 1 fertilization,while the yield per plant was the highest under T 3 fertilization,and the appropriate potassium fertilization was beneficial to increase the fruit of C.oleifera.[Conclusion]This study can provide a reference for the production of C.oleifera young forest.
