From 2010 to 2012, improvement technology test was taken on 6.67 hm2 low-yield Camellia oleifera forest at the Dadong administrative village of Lucheng Town in Chuxiong City , by using 8 techni-cal measures such as clearing weed trees , reclaiming soil , forest land interplanting and intercropping , ra-tional fertilization , dry season irrigation , pruning , cutting dense to fill sparse and high branch grafting . Results showed that the tree height , diameter, crown were increasing year by year , fruit production and oil production increased by 215%, the average crown fruit production per unit area increased by 151%, average fruit weight , average fruit seed weight , and seeds number increased respectively by 34.26%, 34.94%, 42.11%than control .%2010～2012年，对楚雄市鹿城镇大东村委会小坝冲的6.67 hm2油茶低产林采用清除杂木、垦复土壤、林地套种与间作、合理施肥、旱季灌水、整枝修剪、伐密补稀及高枝换接这8项技术措施进行改造试验。结果表明，参试油茶的树高、地径、冠幅均逐年增加，单位面积产油量增幅达215％，单位面积的平均冠幅产果量增幅达151％，平均单果重、平均单果籽重及籽粒数分别比实施前提高34.26％、34.94％、42.11％。
