玫瑰怎么修剪整形
玫瑰怎么修剪整形,玫瑰是在当年生枝条上开花的。因此,合理修剪可使植株生长旺盛,花繁色丽,树形端正,并可延长开花的年限。玫瑰修剪分为花期修剪和休眠期修剪。
(1)花期修剪。第一批花开放后,在花枝基部以上15~20厘米处短截,促发新枝。
(2)休眠期修剪。早春发芽前每株留4~5条枝条,距地面40~50厘米处短截,每枝留1~2个侧枝,每侧枝上留两个芽短截。一株玫瑰寿命可长达20余年,3年生的植株开花最盛,4~5年后开始衰退,花的产量和质量下降,因此,需要进行更新复壮。
方法是:对定植4~5年的玫瑰,在冬季将老根翻出,剔除病虫枝、衰老枝后进行重栽,并对过密过旺的株丛进行分株,或在秋、冬季节将衰老的玫瑰植株齐地面剪除,然后翻耕玫瑰行间土壤,施入饼肥,浇足水。这样,次年虽产花不多,但以后2~3年产花量会有很大的提高,以上就是关于玫瑰怎么修剪整形的介绍。
