楚雄州油茶低产林改造技术试验效果初报

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%。

Preliminary Result of Low-yield Camellia Oleifera Forest Improvement Technology Test in Chuxiong

From 2010 to 2012,improvement technology test was taken on 6. 67 hm2low-yield Camellia oleifera forest at the Dadong administrative village of Lucheng Town in Chuxiong City,by using 8 technical measures such as clearing weed trees,reclaiming soil,forest land interplanting and intercropping,rational 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.
