摘要
通过兴国县现有油茶林分进行群体结构调查分析,结果表明在兴国县现有油茶林分品种(类型)混杂,以黄球球类型最多,依次为青球,红球、黄桃、青桃,这5种品种(类型)分布约占全县94.8%。林分生长发育存在差异,综合表现以黄桃最好。全县平均单位面积株数78株/667m2,林分密度基本合理,但同一地段不同林分、不同地段林分间密度存在显著差异。林相不齐,疏密不均,植株大小不一,表现在全县平均整齐度仅为2.44,为现有油茶林栽培管理和低产林改造提供科学依据。
The group structure of Camellia oleifera stand in Xingguo County was investigated analyzed,the results showed that the existing types of C.oleifera were mixed up with majority yellow ball,following with green ball,red ball,yellow peach,green peach.All of the five types were accounting for 94.8% in Xingguo County.There were differences of the stand either growth or development and the best was yellow peach.The average number of trees per unit area was 1 170/hm2,forestry density was reasonable,but the difference between the different area and same area with different density was serious.No neat stand,different age,different size was reflecting the average canopy uniformity was only 2.44.It may provide a scientific basis for C.oleifera cultivation and management and the transformation of low-yield forests.
