摘要
针对广东省龙川县油茶(Camellia oleiferaAbel.)低产低效问题,实行了整形修剪、垦复抚育以及合理施肥的措施。标准地调查结果表明:油茶低产林改造的增产作用显著,每亩增产鲜果50kg,且树体明显增大;施肥后土壤营养情况有明显变化,氮、磷和钾含量增多。这说明油茶低产林的改造提高了其经济效益。
To address low production and effectiveness of tea-oil tree （Camellia oleifera Abel.） forest in Longchuan of Guangdong Province, we took the measures of reshapfng ＆ pruning, reclamation pending, and rational fertilization. Sample plot survey showed that： （1） tea-oil tree yield increased significantly by 50 kg per mu （1/15 ha） and the tree size also increased remarkably after improving low-production teaoil tree forest; and （2） soil nutrition changed dramatically with N, P and K content increasing. These indicated that the improvement of Iow--yfeld teaoil tree forest enhanced its economic benefit.
