【摘要】 四季杜鹃的全光喷雾扦插结果表明:3种生根促进剂NAA、IBA、ABT-2号生根粉对插条具有良好的促根作用,其中以ABT-2号生根粉0.6 mg/L浸泡插条基部2 h效果最佳,生根率达84 %。当年生壮实半木质化新枝是四季杜鹃理想的扦插材料。插条生根后追肥有利于获得壮苗。更多还原

【Abstract】 The present experiment indicated that three kinds of rootgenesis regulators(NAA、IBA、ABT-2) had good effects on the full-sunlight spraying cutting of Rododendron hybrid.
