不同整地方式对绿化树种球花石楠生长量的影响

Effects of Different Site Preparation Methods on the Growth of Photinia glomerata

开展3种不同整地方式对球花石楠幼树成活率、保存率、树高和地径生长量的影响研究,结果表明:成活率是处理A>B>C,保存率是B>A>C,树高和地径的生长量均是A>B>C。从方差分析和多重比较分析看,树高生长处理A和处理B、C间存在极显著差异,处理B与处理C间差异不显著。地径生长,3个处理间均存在极显著差异。从整地方式、造林成本对幼树的成活率、保存率、树高、地径的生长来看,较适合球花石楠的成活率、保存率、树高和地径生长的处理是处理B,即人工打塘处理。

In this paper,3 different site preparation ways were used to study their effect on the sapling survival rate, the conservation rate, the tree height and the ground diameter increment of Photinia glomerata. The results indicated that the survival rate was treatment A 〉 B 〉 C, the conservation rate was trentment B 〉 A 〉 C, the tree eight and the ground diameter growth increment were treatment A 〉 B 〉 C.
