摘　　要：旨在探讨不同造林抚育方式对油茶幼林生长的影响,以期为优化油茶幼林管理提供参考。试验设置脱袋与未脱袋处理及人工除草与喷施除草剂4个处理组。结果显示:脱袋处理对油茶幼林的株高和冠幅生长均有显著促进作用。脱袋处理组的株高较未脱袋处理组分别提高了21.97%(人工除草)和27.44%(喷施除草剂);冠幅方面,脱袋处理组A和处理组B的冠幅显著高于未脱袋处理组C和处理组D,分别提高了5.26 cm和4.04 cm。此外,除草方式对油茶幼林的株高和冠幅生长也有显著影响。人工除草的处理组A和处理组C的株高普遍高于喷施除草剂的处理组B和处理组D,株高分别提高了7.71%(脱袋)和12.55%(未脱袋);冠幅方面,人工除草处理组A和处理组C较喷施除草剂处理组B和处理组D分别提高了12.47%(脱袋)和9.08%(未脱袋)。指出了脱袋处理和人工除草对油茶幼林的株高和冠幅生长均有显著的促进作用。建议在油茶幼林的管理中,优先考虑脱袋处理和人工除草方式,以优化油茶幼林的生长表现,提高生产效益。The purpose of this study was to investigate the effects of different planting and tending methods on the growth of Camellia oleifera Abel young forest,in order to provide scientific basis for optimizing the management of Camellia oleifera Abel young forest.Four treatment groups were set up in the experiment:bag removal and non-bag removal treatment,manual weeding and herbicide spraying.The results showed that debagging had a significant effect on the growth of plant height and crown width of young forest.The plant height of the unbagged group was increased by 21.97%(manual weeding)and 27.44%(spraying herbicide),respectively.In terms of crown width,the crown width of group A and B was significantly higher than that of group C and D without bag removal,which increased by 5.26 cm and 4.04 cm,respectively.In addition,the way of weeding also had a significant effect on the growth of tree height and crown width of the young forest.The plant height of artificially weeded treatment group A and C was generally higher than that of sprayed herbicide treatment group B and D,and the plant height increased by 7.71%(bagged)and 12.55%(unbagged),respectively.In terms of crown width,the increase of 12.47%(unbagged)and 9.08%(unbagged)in manual weeding treatment group A and C was higher than that in spraying herbicide treatment group B and D,respectively.The results showed that debagging treatment and artificial weeding had a significant effect on the growth of plant height and crown width of the young forest.Therefore,it is suggested that in the management of young Camellia Oleifera.Abel forest,priority should be given to debagging treatment and artificial weeding in order to optimize the growth performance of young Camellia Oleifera.Abel forest and improve the production efficiency.
