摘  要:
从植物生长物质种类及浓度、扦插时期、母株年龄和穗条粗度对鸡血藤硬枝扦插繁殖技术进行了研究。结果表明,用100 mg/L的IBA和200 mg/L的ABT2混和溶液浸泡2 h的枝条生根率最高,为84.7%;最适宜的扦插时期是12月下旬至次年1月中旬,成活率可达82.7%,但生根和新芽萌发时间均要40 d左右;鸡血藤硬枝扦插有显著的年龄效应,超过8年生的母株枝条不宜扦插;用径粗0.7~1.0 cm穗条扦插时,生根率最高,在81.3%~85.0%。

摘  要:
Comparative experiments of seedling cultivation by soft cottage of Spatholobus suberectus were conducted on different concentration of different hormones,different operation time,different aged mother plant,different scion size.The results showed that it had the best effect of rooting rate(84.7%) when cuttings were soaked 2 hours in mixed solution of 100 mg/L of IBA and 200mg/L of ABT2.The suitable cutting time was from late December to mid-January,with the survival rate to 82.7%.Cuttings needed about 40 days for rooting and new shoot sprouting.It had significant effect of age for hard cuttings Mother branch with more than 8 years should not be cutting.Rooting rate of cuttings could reach 81.3%-85.0% with scions diameter of 0.7-1.0 cm.
