盆栽花卉何时修剪好?
花卉种类繁多,不同类型的花木,修剪的时间不同。修剪观花类的花木时,首先要掌握不同花木的开花习性。凡春季开花的,如梅、碧桃、迎春等,其花芽是在头一年枝条上形成的,因此冬季不应修剪,早春发芽时也不宜修剪,否则会剪掉花枝。而应在开花后1~2周内修剪,促使萌发新梢,又可形成来年的花枝。
如果等到秋、冬修剪,夏季已形成有花芽的枝条就会受到损伤,影响第二年开花。凡在当年生枝条上开花的花木,如月季、扶桑、一品红、木芙蓉、金橘、佛手等,应在冬季休眠期进行修剪。促其多发新梢、多开花、多结果。
少数灌木,如紫荆等,花芽着生在多年枝条上,进入开花龄植株修剪量较小,可在早春将枝条先端枯干部分剪除。
总之,花木的修剪,根据需要四季可以进行。但主要集中在冬、夏两季,冬季修剪较重,在秋季落叶后至早春萌芽前进行。具体时间应根据树种和地区来定,夏季树液流动旺盛,宜少修剪,可通过摘心、抹芽、疏果等手段来调节。
