摘 要:为指导镇安县油茶生产提质增效、健康发展,在分析现有天然古油茶林(树)、20世纪70年代栽植的油茶林生长与经济产量基础上,分析提出了代产低效林改造及丰产林营建关键技术。丰产林应选择县域东南部、海拔500~1000 m、土层超过1 m,缓坡地中下部阳坡、半阳坡;栽植良种镇油1号和镇油33号优良品种优质苗木,注意整形修剪和间作低矮农作物、扩盘施肥。地产低效林应砍灌清坡,疏密补稀,控制密度在750~830株·hm^(-2),整形修剪,截干复壮。To guide the development of Camellia oleifera Abel industry based on quality and in efficiency,naturally grown old trees of Camellia oleifera Abel,cultivation experience in 70's of last century regarding tree growing and yield,key technologies of high-yield cultivation and low-efficiency improvement were developed.Plantation for high-yield production are proposed to be located in the southeast part of the county,with elevation ranging from 500m to 1000 m,soil layer over 1m,middle to low part of slow sunny slope,or semi-sunny slope.Fine varieties like Zhenyou No.1 and Zhenyou No.33 are applied for seedling production.Attentions should be paid to pruning and training,intercropping with low-height crops.Density controlled at 750-830plants/hm^(2),shrub-cutting to make room for Camellia oleifera Abel,stumping for rejuvenation as well as pruning and training are recommended for low-efficiency plantation improvement.
