花木嫁接有什么好处

Miss Chen

将一种植物的枝条或芽(通称接穗)等营养器官,通过手术接到另一株(通称砧木)植物上,这种操作方法就叫做植物嫁接。很多种花果木如蜡梅、四季橘、碧桃、梅花、桂花、苹果、梨等大多是用嫁接方法培育的,嫁接繁殖有什么好处呢?

一、能保存住花卉或果树优良品种的经济性状。
二、砧木生长适应性强,接后能使优良花木提前开花结果,并增强抗涝、抗寒等能力。



三、选择矮化砧木,可使盆栽苹果、梨、樱桃等果树矮化,结果早、果实大,品质好。

四、用嫁接法可以植皮修补病虫害或机械损伤的珍贵苗木。

花卉嫁接的方法:一种是用枝条作接穗的称为枝接,另一种用单芽作接穗的叫做芽接。在枝接方法中常用的有切接、靠接、劈接。芽接(俗称热粘皮)常用芽片接、套皮接等方法。另外还有根接、二重砧木接等方法。
