                棗樹嫁接砧木的處理方法有哪些?

                  1、削取帶木質棗樹芽片

                  用修枝剪在棗樹側芽上方1-2毫米處剪去原來保留的二次枝殘樁,同時除去針刺。削芽時,一手在所取主芽的上方握住枝條,一手持刀,在二次枝與一次枝的交叉處,從上向下平推第一刀,長約3.5-4厘米,這為長削面;在第一刀的終端上方0.5厘米處,橫向向下斜切第二刀,切至第一刀ζ交界處,夾角為30度,此為短削面。

                  如棗樹接穗ζ 過粗時,有時長削面會出現縱向條紋狀突起,可翻轉過來,小心削去突起部分,使長削面達到平滑。

                  2、棗樹嫁接砧木的處理方法

                  春夏接時,在棗樹距地面20厘米處剪砧,除去上面的二次枝及針刺。秋∞接當年不用剪砧,把棗樹苗木下部20-50厘米以下的二次枝及針◆刺除去。在棗樹距地面10厘米處選一個平直光滑面,一手扶住砧木一手向下斜方推第一刀,長度比接芽長削面略長一些,寬度與接芽同,再在刀口終端點上方0.5厘米處橫向斜切第二刀,同接穗的短削面。去掉砧片。

                  3、嫁接操作

                  把取下的棗樹芽片迅速鑲嵌於砧木切口上,使下斜口和左右兩邊【的形成層對齊。用彈性好、拉力大、柔軟度好的塑膜帶從下往上纏嚴綁緊,露出芽體部分即可。
