2009年引进长林系列8个优良油茶品种，栽植后连续2 a对其在不同立地条件下的生长量进行对比试验。结果表明：不同海拔高度，油茶当年生长无明显差异，第二年苗木生长的地径、树高与海拔高度的关系均达到差异极显著水平，中、低海拔生长的油茶在树高、地径生长量之间无明显差异，而中、低海拔与高海拔生长的油茶在树高、地径生长量之间有明显差异；不同坡向对油茶高生长有显著影响，南坡的生长最好，东坡生长次之，北坡生长最差；不同坡位对油茶高生长有显著影响，对地径生长则无明显差异，中、下坡的生长较好，上坡的生长较差。油茶造林应选择海拔在600 m以下，坡向为东、南坡，坡位为中、下坡的地段造林为好。%Introduction of 8 improved cultivars of 2-year Camellia oleifera seedling in 2009 in Jingning, Zhejiang province. Comparisons were conducted on increment of seedlings during 2 years under different site conditions. The result demonstrated that growth of the current year of seedling at different altitude had no evident difference, but that of the second year had significant difference of ground diameter and height. There were no evident differences of height and ground diameter growth of seedling between at medium and low altitude, but evident with that at high altitude. Aspect had great effect on growth of seedlings. The growth of seedlings on south slope was better than that on east and north one. Slope site had evident effect on seedling height growth. The experiment resulted that plantation of C. oleifera was recommended on east or south medium or low slope below altitude of 600m.
