摘要
采用2个处理4次重复的随机区组设计进行不同光照条件对楠木人工林生长的影响研究,结果表明:光照条件对楠木人工林生长有较大影响 全光照条件下造林的楠木人工林生长良好,而在阔叶树林冠下造林楠木的生长很差,全光照条件下楠木平均胸径达7 81cm,平均树高达7 36m,平均单株材积达0 0195m3,平均冠幅达2 28m,分别是林冠下楠木的2 5、2 1、9 3和1 8倍 楠木幼树能耐一定的阴蔽,能在林冠下生长,但随着年龄的增长,需光量逐渐增强,成林需全光照,研究结果纠正了人们长期对楠木认识上的偏差。
The effects of light on growth of XPhoebe bourneit plantation were studied by the randomized complete block design of two treatments and four replications. The results showed that:there was significant influence on growth of different treatments of Phoebe bournei plantation. The average DBH,height and volume of Phoebe bournei in the whole light treatment were 7.81 cm,(7.36 m) and( 0.019 5 m^3) respectively,which were 2.5, 2.1,9.3 and 1.8 times as large as those under crown treatment. As stand age increase,Phoebe bournei plantation needs more light for their growth. This research was very useful for the silviculture of Phoebe bournei.
