摘要
本文研究了3种修枝强度对湿地松幼林生长的影响。结果表明:修枝强度为1/3树高,即保留树高2/3的枝桠时,湿地松幼林生长量最大。生产实践表明,对于湿地松丰产林而言,除了适度修枝之外,还要加强抚育管理与病虫害防治,适量施肥,以促进林木健康生长。
This paper studied 3 kinds of pruning intensity affected the growth of young forest of Pinus elliottii.The results showed that when pruning intensity was one third of the tree height （branch height was at two third of the tree height）, the amount of growth of young forest was the largest. Production practice showed that in order to achieve high yield,Pinus eUiottii not only needed proper pruning, but also needed strengthen management, insect disease prevention and proper fertilization.Therefore, the trees achieved the healthy growth.
