杉木林分密度对套种闽楠树型、光合能力及生物量分配的影响
Effects of stand density of Chinese fir plantation on canopy architecture,photosynthetic capacity,and biomass allocation of Phoebe bournei
[目的]通过探讨不同杉木林分密度林下套种闽楠树型结构、叶片光合及生物量分配格局的适应性变化规律,为杉木近成熟林林分质量精准改造与提升提供科学依据。[方法]选择 21a生杉木人工林为研究对象,通过设置375株/hm2、570株/hm2、630株/hm2和 810株/hm2等4个间伐保留密度处理,分别进行林下套种 900株/hm2闽楠形成杉阔复层林,测定分析林下套种 5a后闽楠冠型、侧枝长度、分枝角、叶片表型、叶绿素荧光参数、SPAD值,以及根、茎、…查看全部>>
[Objective]To investigate the change law of the tree type structure,leaf photosynthesis,and biomass allocation patterns of Phoebe bournei planted under different densities of Chinese fir plantations,and to provide scientific basis for precision transformation and improvement of the quality of nearly mature Chinese fir.[Methods]A 21-year-old Chinese fir plantation was selected as the study subject.Four thinning treatments with residual densities of 375 trees/…查看全部>>
