【摘要】 以20世纪60年代残存的油茶低产林为研究对象,进行了不同截干高度对低产油茶树的生长和产量的影响情况的截干更新试验,以期为油茶低产林截干更新复壮提供技术参考和理论依据。结果表明:不同截干高度对油茶树体冠层高、冠幅、春梢生长等特征存在显著的影响。截干复壮技术对春梢生长质量有明显改善的作用,并能够明显提高单株挂果量和产量,其中80 cm可能是油茶低产林截干效果最优的处理。更多还原

【Abstract】 In this study, the remaining low-yield Camellia oleifera forest in the 1960 s was taken as the research object, and the effect of different stem cutting height on the regeneration of low-yield C. oleifera forest was studied by cutting and regeneration techniques experiment. The results showed that different cutting height had significant effects on the crown height, crown diameter and sprout growth of C. oleifera. The technology of stem cutting and rejuvenation can significantly improve the growth quality of sprout, and can significantly increase fruit quantity and yield, perhaps among which the effect of low yield C. oleifera forest with80 cm cutting height is the best.更多还原
