垂花悬铃花扦插生根的影响因素

【目的】建立垂花悬铃花无性繁殖体系,为垂花悬铃花种苗扩繁提供技术支持。【方法】通过双因素交叉分组试验比较7种生根剂及浓度溶液、3种插穗直径对垂花悬铃花硬枝扦插插穗的生根率、生根量、最长根长的影响,采用单因素试验比较7种生根剂及浓度溶液对嫩枝扦插插穗生根效果的影响、5种插穗长度对嫩枝扦插插穗生根效果的影响,同时比较5种基质、施肥与否对扦插苗生长的影响。【结果】硬枝扦插,以直径为1.0~1.5 cm的插穗最好,1000 mg/L IBA溶液生根效果最好,扦插生根率达100.00%,平均生根量57.75条,最长根长9.25 cm。嫩枝扦插,以长度为6.0~7.0 cm的插穗生根效果最好,生根率100...

Summary:【目的】建立垂花悬铃花无性繁殖体系,为垂花悬铃花种苗扩繁提供技术支持。【方法】通过双因素交叉分组试验比较7种生根剂及浓度溶液、3种插穗直径对垂花悬铃花硬枝扦插插穗的生根率、生根量、最长根长的影响,采用单因素试验比较7种生根剂及浓度溶液对嫩枝扦插插穗生根效果的影响、5种插穗长度对嫩枝扦插插穗生根效果的影响,同时比较5种基质、施肥与否对扦插苗生长的影响。【结果】硬枝扦插,以直径为1.0~1.5 cm的插穗最好,1000 mg/L IBA溶液生根效果最好,扦插生根率达100.00%,平均生根量57.75条,最长根长9.25 cm。嫩枝扦插,以长度为6.0~7.0 cm的插穗生根效果最好,生根率100.00%,平均生根数8.83条,最长根长4.43 cm;1000 mg/L GGR-6生根效果最好,生根率为99.26%,平均生根量3.63条,最长根长2.69 cm。移栽基质以泥炭土最佳,移栽7 d后开始施肥,每10 d施一次复合肥（N∶P∶K=15∶15∶15）1600倍液能有效促进扦插苗生长。【结论】垂花悬铃花能通过硬枝扦插和嫩枝扦插快速繁育种苗。

[ Objective ]In the present study, vegetative propagation system of Malvaviscus arboreus was established,in order to provide technical support for M. arboreus seedling propagation. [ Method ]The effects of seven treatments （different kinds of rooting agents and different concentrations） and three kinds of cutting diameters on rooting rate, root number and maximum root length of hardwood-cuttings were investigated by two factors cross grouping tests. The effects of seven treat- ments（different kinds of rooting agents and different concentrations） of rooting agents and five kinds of cuttings length on softwood cuttings were investigated by single factor test. The effects of five kinds of transplanting media and fertilization on growth of cutting seedlin
