摘　　要：以5 a生尾巨桉DH32-28萌芽林为研究对象,设置施肥与不施肥处理,进行比较分析,研究了施肥对尾巨桉无性系近熟林生长的影响。结果表明:进行施肥处理林分的胸径、树高、单株材积和蓄积量生长都达到显著水平,施肥处理林分桉树中径材比例为39.2%,比CK高14.1%。研究还表明,施肥有利于尾巨桉无性系近熟林的生长,增产效应明显。此研究结果对尾巨桉无性系近熟林高质高效培育有重要示范意义,有利于提高桉树经营者的经济效益,助力乡村振兴和经济发展。Taking the 5-year-old germination forest of Eucalyptus grandis DH32-28 as the research object,the effects of fertilization and no fertilization on the growth of Eucalyptus urophylla clones near mature forest were compared and analyzed.The results showed that the DBH,tree height,single plant volume and volume growth of Eucalyptus urophylla clones under fertilization treatment reached a significant level.The proportion of medium diameter wood of Eucalyptus in fertilization treatment stand was 39.2%,which was 14.1%higher than CK.This test shows that fertilization was conducive to the growth of Eucalyptus urophylla clones near mature forest.The effect of increasing production is obvious.The results of this study have important demonstration significance for the high-quality and efficient cultivation of near mature Eucalyptus urophylla clones,which is conducive to improving the economic benefits of Eucalyptus operators and help rural revitalization and economic development.
