摘要:
2009年采用正交区组设计不同密度、不同修枝强度和不同修枝时间3个试验因素对贵州省修文县2年生猴樟(Cinnamomum bodinieri)人工林冠层特性的影响,2011年调查结果表明:猴樟人工林密度为2 505株/hm2时,各处理叶面积指数较高,为0.64 ~ 1.28,叶平均倾角为13.87 ~ 14.51°,透光率较大为0.21 ~ 0.49;密度为3 330株/hm2时,叶面积指数为0.76 ~ 1.52为最高;密度为1 665株/hm2时,叶面积指数为0.54 ~ 0.94,叶平均倾角为10.19 ~ 10.84°,透光率最大为0.21 ~ 0.58。修枝处理的猴樟林分冠层结构优于不修枝的林分。修枝季节对于猴樟林分冠层的影响不大。猴樟人工林在密度为2 505株/ hm2、修枝强度为1/3、修枝季节为春季的组合为猴樟人工林冠层结构的最佳组合。
Abstract:
Experiments were carried out in 2009 on effect of different density, pruning intensity and pruning time on canopy characteristics of Cinnamomum bodinieri plantation in Xiuwen, Guizhou province, with orthogonal design. Investigations in 2011 demonstrated that leaf area index ranged from 0.64 to 1.28, mean leaf angle was 13.87°-14.51°, light transmittance was 0.21-0.49 at stands with density of 2505 trees/ha with different pruning intensity and time. Stand with density of 3330 tree/ha had the highest leaf area index of 0.76-1.52, and that with density of 1665 tree/ha had the largest light transmittance, up to 0.58. Stand with pruning treatments had better canopy structure than that without pruning. Pruning time had no great effect on stand canopy. The experiment resulted that the plantation with density of 2505 tree/ha, pruning of 1/3 branch in spring had the best canopy structure.
