为分析浙江省丽水市油茶低产林形成的原因并提出相应的改造措施,对丽水市3个油茶低产林基地的林分结构、产量和果实性状进行了调查和研究。结果表明：目前的油茶低产林疏密不均,林地利用不合理;鲜茶果产量为40.57～75.80 kg/667m2之间,茶油产量为2.54～4.74 kg/667m2,产量较低;果壳厚0.20～0.33 cm,鲜出籽率37.2%～47.4%,品种较差。

In order to analyze the reasons for the formation of low-yield plantations of Camellia oleifera in Lishui City of Zhejiang Province,and some reform measures were proposed.The stand structure,yield and fruit characters of three low-yield plantations bases of C.oleifera were surveyed and researched.The results showed that：low-yield plantations bases of C.oleifera have uneven density,and also have irrational use of forest land;yield of fresh C.oleifera fruit was between 40.57～75.80 kg/667m2,lower yield of C.oleifera oil was 2.54～4.74 kg/667m2;husk thickness was 0.20～0.33 cm,fresh seed rate was 37.2% to 47.4% and with poor varieties.
