换床移栽对油茶芽苗砧嫁接苗生长发育和造林成活率的影响

Effect of Transplantation on Growth of Embryonal Axis Grafted Camellia oleifera Seedlings and Survival Rate of Afforestation

研究了油茶(Camellia oleifera)芽苗砧嫁接育苗过程中换床移栽对油茶芽苗砧嫁接苗木地径、苗高、侧根数、根系总长度和苗木山上造林成活率的影响。结果表明:换床移栽处理对油茶苗木的生长产生了显著的影响,2年生苗地径、侧根数、根系总长度分别比对照提高15.3%、47%、63%;苗高比对照下降12.8%;苗木造林成活率比对照提高11%。

Experiments were conducted on transplantation of embryonal axis grafted seedlings of Camellia oleifera in 2011in Qingtian, Zhejiangprovince. The result demonstrated that ground diameter, number of lateral roots, total root length of 2-year treated seedlings increased by 15.3%, 47%and 63% compared to that of the control（non transplantation）, height was decreased by 12.8 %. Survival rate of afforestation increased by 11%compared to that of the control.
