摘要
在辽宁省辽阳市喀左县山杏林分布区10a、20a、30a生3个林龄的山杏林内按不同密度设置标准地,在标准地内选择标准株进行调查,并对调查数据运用多重比较法,研究不同林龄不同密度条件下山杏生长和林下土壤性质差异,得出不同林龄下最佳的山杏栽植密度。
The standard plots were set up in different;density in 10a, 20a and 30a of three forest ages of Arrneniaca sibirica respectively in Kezuo county of Liaoning Province. And standard plants were selected from standard plots to investigate and to study the differences in the growth of Armeniaca sibirica and soil quality under different densities with the method of multi-comparison. As a result, it achieved the optimum density of planting Armeniaca sibirica under different forest ages.
