三角梅为常绿攀援状灌木,喜温暖湿润气候,不耐寒,喜充足光照,常用于绿篱、庭园花木等。那么三角梅是如何养殖的呢?养殖中又有什么好的方法呢?三角梅的养殖方法和注意事项是什么呢?请您带着疑问和我一起往下阅读吧!

三角梅的养殖方法(基本知识):

最佳繁殖时间:一般扦插季节宜为3~6月份进行,杭州在5月下旬~6月上旬,入梅前扦插最好。

最佳生长土壤:三角梅对土壤要求不严,耐瘠薄干旱,忌积水。以富含腐殖质、疏松、肥沃、通透性强的沙质土壤为好,忌用黏土。

生长湿度要求:养殖三角梅时需要保持盆土呈湿润状态。

最佳生长温度:三角梅生长适温为15~30℃,在夏季应适当遮荫或采取喷水、通风等措施,冬季应维持不低于5℃的环境温度。

最佳生长光照:一年四季除新上盆的小苗应先放于半阴处。冬季应摆放于南向窗前,且光照时间不能少于8个小时。

养殖三角梅的注意事项:

施撒肥料:三角梅需要一定的养分,在生长期内要进行适当的施肥,才能满足其生长的需要。肥料应腐熟,施肥应少量多次,浓度要淡,否则,易伤害根系,影响生长。

定植上盆:三角梅扦插枝成活后的分植上盆,扦插40天成活的小苗在强阳光下炼苗一周,浇薄肥。50~60天分植上盆,扦插苗连盆放水盆中,将基质与根漂离,或直接倒出根分离后带部分基质种入培养土中。

浇水要点:浇水在三角梅的养殖方法和注意事项中也是非常重要的一点,三角梅在开花前要控水,叶子花的平时浇水掌握“不干不浇,浇则要透”的原则。但要使叶子花开花整齐、多花,开花前必须进行控水。

从9月份开始对叶子花的浇水进行控制,每次浇水要等到盆土干燥、枝叶软垂后方可进行,如此反复连续半个月时间,半个月后恢复平时正常浇水。控水期间切忌施肥,以免肥料烧伤根系。这样约一个月时间,叶子花即可显蕾开花,而且花开放整齐、繁盛。

繁殖要点:

(1)扦插繁殖:叶子花繁殖以扦插为主,夏季扦插成活率高,插穗宜选择一年生半木质化枝条,剪成10~15cm的段,插于沙床中,在20~25℃的温度下,20~25天可生根,40天后上盆,第二年入冬即可开花。如扦插前用激素处理,可促进生根,提高成活率。

(2)高压繁殖:压条可用普通压条法,多在春秋进行,可先将压条部位刻伤,然后压埋于土中,保持20℃以上温度,20天左右可发根。

修剪要领:三角梅在修剪时应掌握“短、重、疏”的原则,即短截水平枝,重剪新生枝。疏去密枝、弱枝。红花三角梅长势较弱,每年约在3~4月修剪1次;紫花三角梅每年需全面修剪2次,第一次在3~4月发芽前,第二次在11~12月花谢后新枝生长前,以保证年年开花旺盛。

盆土更换:三角梅生长速度较快,根系发达,须根甚多,每年需换盆一次。三角梅由于长期浇水、施肥和雨水冲刷,盆土容易板结,因此,必须定期松土,同时清除盆土杂草,以利于三角梅生长。否则盆土板结、积水,容易造成三角梅根系腐烂或生长不良。

浇水要求:春秋两季应每天浇水一次,夏季可每天早晚各浇一次水,冬季应控制浇水花蕾出现后每天早晚各浇水一次,同时向叶面喷水1~2次。梅雨季节要防积水以免植株烂根死亡。

病虫防治:三角梅常见的害虫主要有叶甲和蚜虫,常见病害主要有枯梢病。平时要加强松土除草,及时清除枯枝、病叶,注意通气,以减少病源的传播。加强病情检查,发现病情及时处理,可用乐果、托布津等溶液防治。

养殖三角梅的心得:

1、冬季不低于5℃的温度三角梅可以安全越冬,否则就要防冻保暖或移入室内养护。

2、三角梅在强光、高温下,制水长花。三角梅特喜强光和高温,不怕曝晒,却对水分要求不多,盆土只要保持湿润即可。特别是秋初要制水一个月,保持半干半湿。致使绿叶掉落也没关系,反而有利长花。

结语:通过上文的介绍,相信大家都了解了三角梅的养殖方法和注意事项,希望大家都可以培育出美丽的三角梅!
