对岑溪软枝油茶采穗圃进行控花控果对比试验，结果表明：摘除花果能促进采穗圃春梢早发芽，春梢的梢枝数、小枝长和小枝基径分别比对照增加7.03%～31.30%、32.63%～64.20%和31.12%～36.47%；摘除花果对不同品系油茶春梢的影响也不同，摘除花果对无性系3有较好的促进作用，而对无性系1和无性系2的效果不如无性系3；对油茶进行控花控果在阴坡的效果好于阳坡。

Abstract: |
|
The efficiency of removal of flowers and fruits (hereafter referred as removal treatment) for promoting branch growth of Camellia oleifera in spring were tested in Meizhou, Guangdong. The results are as follows: the removal treatment make earlier shoots in spring than the control (keep flowers and fruits). Compared with the control, the removal treatment make the numbers of shoot (7.03%～31.30%), the length (32.63%～64.20%) and basal diameter (31.12%～36.47%) of new branches higher. The removal has different impacts on the three clones. The clone 3 grow better than clone 1 and 2 after the removal. C. oleifera on the shade hillside grow better than those on the sunny hillside after removal.
