杜鹃株形的培养,是通过对枝条的修剪与整理来完成的。大致需要掌握这样几个环节: 了解杜鹃的生长能力和萌发规律杜鹃是生长和萌发能力都很强的花卉,又具有叶芽丰富、芽眼分布广泛、发芽繁多的特点。它的芽眼分布于全身,就是说它全身都有萌发新芽的能力。按芽眼分布的位置,可分为顶芽(位于所有枝头的顶尖)、腋芽(位于叶柄基部内侧与茎的交汇处)、不定芽(干、茎、枝所有部位都有芽眼存在,因它的不定性,称为不定芽,又因其具有潜伏性,也叫潜伏芽)和脚芽(位于与土面接触的根部)(见图)。正常情况下,只有顶芽和腋芽在春季处于萌生状态。而不定芽和脚芽萌发是很不规律的,条件适宜时,一年四季都有可能萌发,且萌发快,长势旺,只是数量少,不定时。杜鹃的萌发规律是这样的。花期结束的春季是萌发新芽的高峰,全年的骨干枝都是在这时形成的。夏秋两季,一些迟发的春芽和不定芽也会相继抽发,虽不像春芽那样多,但说不定恰是整形所需要的理想枝条,可充分利用,余者去除。冬季也会抽发新芽,但数量少,质量差,必须及时去掉。抓住修剪的时机根据植株生长的态
Rhododendron strain-shaped culture, is through the branches trimmed and finishing to complete. Generally need to grasp such a few links: Understanding of rhododendron growth and germination rules Rhododendron is a strong growth and germination ability of flowers, but also has a rich leaf buds, widely distributed buds, sprouting and many features. Its bud is distributed throughout the body, meaning that it has the ability to germinate all over the body. According to the distribution of the bud eye can be divided into the top bud (located in the top of all branches), axillary buds (located in the medial base of the petiole and the stem of the junction), adventitious buds (stems, stems, branches all bud eye exists because it Of uncertainty, called adventitious buds, but also because of its latent, also called latent buds) and foot buds (located in contact with the soil surface) (see figure). Under normal circumstances, only the top buds and axillary buds are sprouting in spring. And adventitious buds and buds are very irregular germination, when conditions are right, germination may occur all year round, and the germination of fast, prosperous, but the number of small, irregular. Rhododendron germination rules are like this. Spring is the end of the flowering sprout germination peak, the backbone of the branch are all formed at this time. Summer and autumn, some delayed spring buds and adventitious buds will also be pumping one after another, though not as many as spring buds, but maybe the ideal branch needed for plastic surgery can take full advantage of the remaining removal. Winter will also sprout, but the number of small, poor quality, must be promptly removed. Grasp the timing of pruning according to the state of plant growth
