夹竹桃,常见栽培的有红花和白花两个品种。笔者近年进行了“一株两色花”的高枝嫁接试验,早春嫁接,当年八、九月在同一植株上即开出了红、白相映的两色花朵,显得俏丽多彩,别具情趣。现将方法介绍如下: 一、砧木培养选一株独干的红花夹竹桃,将主干保留1米左右,剪去顶端,加强肥水管理,促生“三权九顶”树冠。根据色彩搭配的需要,在不同部位的分枝上选部分半木质或已木质化的健壮枝条,离分权 Oleander, common cultivated safflower and white flowers two varieties. In recent years, the author carried out the experiment of “a two-color flower” of high branch grafting, which was grafted in early spring. In August and September of the same year, flowers of two colors, red and white, appeared on the same plant and appeared pretty and colorful with special taste. Now the method is introduced as follows: First, the rootstock culture choose a single dry safflower oleander, the trunk to retain about 1 meter, cut to the top, to strengthen fertilizer and water management, to promote the “three power nine” crown. According to the needs of color matching, the selection of parts in different parts of the semi-woody or lignified robust branches, decentralization
