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％。
2010～2012年，對楚雄市鹿城鎮大東村委會小壩遲的6.67 hm2油茶低產林採用清除雜木、墾複土壤、林地套種與間作、閤理施肥、旱季灌水、整枝脩剪、伐密補稀及高枝換接這8項技術措施進行改造試驗。結果錶明，參試油茶的樹高、地徑、冠幅均逐年增加，單位麵積產油量增幅達215％，單位麵積的平均冠幅產果量增幅達151％，平均單果重、平均單果籽重及籽粒數分彆比實施前提高34.26％、34.94％、42.11％。
2010～2012년，대초웅시록성진대동촌위회소패충적6.67 hm2유다저산림채용청제잡목、은복토양、임지투충여간작、합리시비、한계관수、정지수전、벌밀보희급고지환접저8항기술조시진행개조시험。결과표명，삼시유다적수고、지경、관폭균축년증가，단위면적산유량증폭체215％，단위면적적평균관폭산과량증폭체151％，평균단과중、평균단과자중급자립수분별비실시전제고34.26％、34.94％、42.11％。
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 .
