摘要
为了提高油茶造林成活率,减少造林损失,节约管理成本,采用集中管理的4年生芽苗砧嫁接良种油茶苗进行了大苗移栽造林试验,并以1年生、2年生小苗造林试验作对照。结果表明:大苗移栽的造林成活率可达97%以上,比用1年生、2年生小苗造林的成活率几乎提高了1倍。造林试验结果说明,大苗移栽技术是提高油茶造林成活率的关键技术。
In order to improve survival rate of Camellia oleifera forestation,reduce loss of forestation and save cost of management,centralizedly managed four-year grafted improved varieties in C.oleifera seedling were used for forestation experiment,taking one-year and two-year seedlings as CK.The results show that the survival rate of big seedling reaches above 97%,which is double higher than the survival rate of one-year and two-year seedlings.The techniques of big seedling transplantation are key to improving survival rate of C.oleifera forestation.
