第八講.壓條法及嫁接法

壓條法可分為軟枝壓條法及高空壓條法(圈枝法).軟枝壓條法是將植物的枝條彎曲至地上,用土埋好,待長出根部便從母株上切下來,單獨栽培成為一新的植株.高空壓條法是先選兩年以上的枝條,在其下部靠近節的部位環狀剝皮(破壞該部位的韌皮部,促使該處的上方的形成層發根),然後把濕潤的茸草放進透明膠袋內把整個傷口包好,上下兩端扎起來.當生根後,便在壓條部位以下剪斷,盆栽成為新株.通常選在植物的旺盛生長期(在春末夏初),容易生根.

嫁接繁殖可以將優良品種的枝或芽(枝接及芽接)作為接穗嫁接在生長強健,抗性強的砧木上,成為新的獨立植株.

嫁接的好處是較早開花,結果,縮短育種年期;可以通過選擇砧木調節株形,增強對環境的適應力.不過,嫁接也有不足地方,嫁接技術複雜,嫁接苗比以播種方法的壽命短,在接口處明顯肥大,影響觀感.(可參考洋紫荊的例子) 

高空壓條法(或叫圈枝法)

環狀剝皮後再包上茸草

見到根生出來便可以移植
