汉桂两种繁殖方法园艺学差异性调查

Horticultural Differences between Two Propagation Methods for Osmanthus fragrans Lour

汉桂主要有嫁接和扦插两种繁育方法。扦插繁育的汉桂总根数量、平均根粗、立根总量、立根粗度均远大于嫁接繁殖的汉桂。扦插繁育的汉桂根总体上是向下部生长,而嫁接繁育的桂花根多是水平生长。扦插汉桂抗风能力远高于嫁接汉桂,病害发生较轻,生长速度较快,投入产出高,市场优势显著。

Grafting and cuttage are two main breeding methods for Osmanthus fragrans Lour.The total root number,average root diameter,and overall development of cutted Osmanthus fragrans Lour propagated by cuttage were superiorto those of grafted ones.The roots of cuttage-propagated Osmanthus fragrans Lour had a downward growth pattern,while the grafed ones showed horizontal root growth.The cuttings of smanthus fragrans Lour demonstrated higher wind-resistance capabilities compared to grafted ones,particularly in Guangxi Zhuang Autonomous Region.
