来宾地区引种小果油茶成效分析

Effect Analysis of Introducing Camellia meiocarpa in Laibin

为了促进来宾地区油茶产业的健康发展,对来宾地区引种11年的小果油茶(Camellia meiocarpa)种植成效进行分析。结果表明,林分平均株高、地径和冠幅分别为2.35 m、9.56 cm和8.88 m^(2),植株生长健壮,单位面积平均鲜果产量为0.53 kg/m^(2),林地茶油产量为327.91 kg/hm^(2),在全国的小果油茶种植中属中上水平;平均单果重和果径为4.00 g和17.68 mm,低于全国平均水平,但与引种地广西三江差异不大。从植株生长、果实产量和果实经济性状上看,在此区域种植小果油茶可行性大。

To promote healthy development of oil-tea industry in Laibin,planting effects of 11-year-old Camel⁃lia meiocarpa introduced in Laibin were analyzed.Results showed that average plant height,ground diameter and crown width were 2.35 m,9.56 cm and 8.88 m^(2).Plants were healthy and strong.Average yield of fresh fruits per unit area was 0.53 kg/m^(2).Oil yield of forest was 327.91 kg/hm^(2).Planting level of C.meiocarpa in Laibin was above the average in China.Average single fruit weight and fruit diameter were 4.00 g and 17.68 mm,which were lower than national average,however,there were no significant differences compared with introduction site(Sanjiang,Guangxi).It was great feasibility to plant C.meiocarpa in Laibin in terms of plant growth,fruit yield and fruit economic characters.
