                              四月花卉之紫荆的养殖技巧
                              2018-04-02

                              一、紫荆的形态特征

                              落叶丛生灌木,或小乔木。叶大,心脏形。花密4-10朵,簇生老枝上,紫红色。先花后叶。荚果紫红色,10月成熟。变种有白花紫荆等。

                              紫荆

                              二、紫荆的生长习性

                              紫荆是亚热带树种,我国大部分地区均有栽植。性喜光,喜肥沃、湿润土壤,但怕涝,较耐寒。花期:4月份。

                              三、紫荆的栽培管理

                              以播?#22336;?#27542;为主,3-4月进行,?#37096;煞种?#32321;殖。萌发能力强,耐修剪。定植后的幼苗,为了促使其多生分枝,发展根系,应进行轻度短截。翌年早春,重短截,使其萌发出3-5个强健的一年生枝。在生长期,应适当摘心、剪梢。冬季适度疏剪树丛内过密的?#23548;?#26525;、无用枝、枯萎枝等。避免夏季修剪,否则会减少花芽的产生。

                              四、紫荆的应用

                              早春开花,一片紫红,配植在庭园中的墙隅、篱外、草坪边缘、建筑物周围;与常绿乔木配植,对比鲜明,花色更加美丽。?#37096;?#25104;丛布置于庭园、花园一隅。植株对金黄葡?#20122;?#33740;、绿脓肝菌等细菌具有很强的杀菌作用,还有很强的滞尘能力。
