Results showed that diameter at breast height (DBH) of DH32-29 had no significant differences between high and low levels of applied fertilizer. In contrast, DBH of GL9 and also tree height and single tree volume of DH32-29 differed significantly among treatments, with the fertilizers that provided higher levels of available nutrients giving greater growth. Tree height and single tree volume of GL9 showed a trend of faster growth in earlier stage but slower growth potential in later stages. The growth of DH32-29 was greater than that of GL9.%本文以桉树无性系DH32-29和GL9为试验对象，通过设置不同肥种及用量施肥处理研究其对这2种无性系生长的影响。结果表明：在本文设置的肥料有效养分梯度下，DH32-29胸径生长对肥料有效养分含量高低无显著差异，而GL9胸径生长、DH32-29树高生长和单株材积生长表现出明显的高有效养分促进作用；GL9树高和单株材积前期生长较快，后期生长潜力不足；DH32-29生长量较GL9大。 【总页数】5页(P38-42) 【作 者】蒋雪刚;林武;邓玉华;韦建秋;李林艳;雷定战;翟章贵;任世奇 【作者单位】广西国有黄冕林场，广西 柳州 545619;广西国有黄冕林场，广西 柳州 545619;广西国有黄冕林场，广西 柳州 545619;广西国有黄冕林场，广西 柳州 545619;广西国有黄冕林场，广西 柳州 545619;广西国有派阳山林场，广西 宁明 532500;广西国有派阳山林场，广西 宁明 532500;广西林业科学研究院，广西 南宁 530002 【正文语种】中 文 【中图分类】S725.5 【相关文献】 1.桉树人工林对生态环境的影响及桉树生长的影响因素 [J], 陈建贵 2.桉树与几种滨海植物水浸提液对纤细角毛藻生长的影响 [J], 高霆炜;吴斌 3.不同施肥处理对桉树生长的影响 [J], 文亮;阮荣富 4.桉树枝瘿姬小蜂对几种桉树萌芽影响的观察 [J], 王缉健;蒋金培;罗基同;陈基荣;陈江;蓝利萍 5.几种施肥处理对桉树生长的影响 [J], 罗佐成 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.wddqw.com/doc/ba9cf25101020740be1e650e52ea551811a6c95e.html
