【摘 要】Growth of two Eucalyptus clones, DH32-29 and GL9, were studied after application of different types and rates of fertilizer. 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)
