摘要
随机选择同龄乐昌含笑幼树样木,用3种不同修枝强度,进行了2次修枝。并对126株样木数据进行方差分析,结果表明:修枝强度对树高生长影响不显著,对树干直径生长影响差异极显著。
A random sampling was made in young Michelia chapaensis trees with the same age. The sample trees were pruned twice with three different strength. And these 126 trees＇ data were analyzed. The results showed that the strength had no significant difference on the growth of height, but on the growth of diameter the influence was very significant.
