红锥与桉树混交造林试验

Mixed Afforestation Experiments of Castanopsis hystrix with Eucalyptus robusta

对红锥与桉树采用8锥2桉、7锥3桉、6锥4桉3种混交比例进行造林试验,结果表明:采用8锥2桉比例混交,林分中红锥树高、地径、冠幅等指标与红锥纯林的指标相比无显著性差异,说明8锥2桉混交造林,红锥不会被桉树抑制生长,可在生产实践中应用。

Three kinds of mixed proportions （8 Castanopsis h ystrim ＋ 2 Eucalyptus robusta , 7 Castanopsis h ystrim ＋ 3 Eucalyptus robusta, 6 Castanopsis hystrix 4 Eucalyptus robusta） were used to conduct afforestation experiments for Cas tanopsis hystriz ＆ Eucalyptus. Result shows that. the indices of the tree height, ground diameter and crown of Castanopsis hystriz in the stand shows no significance with the pure forest. The proportion （8 Castanopsis hystriz ＋ 2 Eucalyptus ro busta ） were adopted to plant, which shows that adopting 8 Castanopsis hystrix＋ 2 Eucalyptus robusta to plant Castanopsis hystriz can not inhibit the growth of Eucalyptus robusta, it can be used in the practice of production.
