本期彩页上刊发了一组近年引进的高品质一品红,这些新品种的突出特点是株矮形美,“花”大色靓。目前,在园林应用上它已基本取代了原来需要折弯的高杆品种,花卉爱好者栽培的也越来越多。
This issue of color pages published a group of high-quality poinsettia introduced in recent years, the prominent feature of these new varieties is the dwarf beauty of the United States, “flower” big color pretty. At present, it has basically replaced the original need to bend the high bar varieties in the garden applications, flower lovers cultivation is also more and more.
