常绿地被植物“芝樱”的引种栽培及繁育

Ntroduction, Cultivation and Breeding of New Evergreen Ground Cover Plant——Shibazakura

通过对4个“芝樱”品种的引种栽培,观察其生长习性及适应性,研究其繁育方法。结果表明:4个芝樱品种均可以在陕西关中地区适应,白色、紫色品种表现最佳。群体花期2月底-4月下旬,白色、紫色品种可以实现1年2季花,花期最长可达95 d。最佳繁育方法为扦插育苗,最佳扦插繁殖时间5-9月,成活率最高可达99%,生根时间为7~10 d,最佳扦插基质为泥炭土+珍珠岩(1∶1)。

Four varieties of Shibazakura were introduced and cultivated.Their growth habits and adaptability were observed.The results showed that all the four varieties can be adapted to the Guanzhong area of Shaanxi,and the white and purple varieties performed best,with flowering period lasting for two seasons and longest up to 95 d.The best breeding method is cutting.The best time for cutting propagation time is from May to September and the survival rate can reach over 99%,the rooting time 7-10 d,and the best cutting substrate is peat soil+perlite(1∶1).
