摘　　要：对油茶栽植技术和管理措施与成活率的关系进行了试验研究,并结合安徽主要油茶产区栽植成活率与相关因子关系的调查数据,结果表明:(1)油茶裸根苗经过一段时间的运输到达目的地后,高质量的假植不仅能存放较长的时间,而且可以提高栽植成活率,在本试验的20天内,假植时间与栽植成活率呈正相关;(2)摘叶程度为90%、60%、30%、0%时,其栽植成活率分别为87.33%、73.33%、66.67%、63.67%;(3)适当深栽有助于提高苗木的成活率,采用浅栽高培土的方法可避免弱小苗木深栽被土掩埋,同时也能保证根系有一定的土层覆盖;(4)覆草可显著降低土壤体积质量、提高土壤水分,被覆草的容器苗和裸根苗成活率分别增长了9.00%和19.27%。In this paper the relationship between planting techniques and management measures of Camellia oleifera grafted plants and their survival rate were studied and the factors affecting the survival rate of oil-tea were investigated in the main planting areas in Anhui province.The results showed that after a long time transportation,the high quality heeling of oil-tea grafted plants could not only deposit longer time,but also enhance the survival rate within 20 days in this experiment.The survival rate was 87.33%,73.33%,66.67% and 63.67% when picking leaf level was 90%,60%,30% and 0% respectively.The grafted plants planted relatively deep could enhance their survival rate,and the small and weak grafted plants planted with hilling could be avoided to be buried by the soil,and also ensured the root system in the deeper soil.With the treatment of mulching grass,the survival rate of the container grafted plants and the bare-root grafted plants increased 9.00% and 19.27% respectively.
