对普通油茶低产林在不同经营管理下的改造成效进行分析.结果表明:不同经营管理下油茶低产林改造效果差异明显,精细管理能显著提高油茶低产林产量,尤其在结实小年增产效果更明显;仅通过密度调整和土壤垦复等粗放管理无法达到增产效果.从投入产出比看,2018-2022 年精细管理的油茶低产林投入产出比为 50.9%,高于粗放管理(40.57%)和未抚育管理的对照(23.80%),改造效果明显.
Analysis on the effect of low yield forest transformation of Camellia oleifera
Analyze the transformation effects of low yield Camellia oleifera forests under different management practices.,the results showed that there were significant differences in the transformation effects of low yield C.oleifera forests under different management strategies.Fine management significantly increased the fruit yield,and the yield increase was more pronounced in years with low fruiting.The yield increase could not be achieved solely through extensive management practices such as density adjustment and soil reclamation.From the perspective of input-output ratio,the input-output ratio of low-yielding C.oleifera forests under fine management from 2018 to 2022 was 50.9%,which was higher than the 40.57%under extensive management and the 23.80%of the control forests with untreated management,and the transformation effect was significant.
