苹果苗基地批发==出售苹果苗=山西苹果苗价格,山西绛县稚茹苗木经销部面向全国批发苹果苗,大苹果苗,嫁接苹果苗,实生苹果苗,矮化苹果苗等。苹果(Maluspumila Mill.):是落叶乔木,通常树木可高至15米,但栽培树木一般只高3-5米左右。树干呈灰褐色,树皮有一定程度的脱落。苹果树开花期是基于各地气候而定,但一般集中在4-5月份。苹果是异花授粉植物,大部分品种自花不能结成果实。
苹果树是乔木,高可达15米,多具有圆形树冠和短主干;小枝短而粗,圆柱形,幼嫩时密被绒毛,老枝紫褐色,无毛;冬芽卵形,先端钝,密被短柔毛。
叶片椭圆形、卵形至宽椭圆形,长4.5-10厘米,宽3-5.5厘米,先端急尖,基部宽楔形或圆形,边缘具有圆钝锯齿,幼嫩时两面具短柔毛,长成后上面无毛;叶柄粗壮,长约1.5-3厘米,被短柔毛;托叶草质,披针形,先端渐尖,全缘,密被短柔毛,早落。
伞房花序,具花3-7朵,集生于小枝顶端,花梗长1-2.5厘米,密被绒毛;苞片膜质,线状披针形,先端渐尖,全缘,被绒毛;花直径3-4厘米;萼筒外面密被绒毛;萼片三角披针形或三角卵形,长6-8毫米,先端渐尖,全缘,内外两面均密被绒毛,萼片比萼筒长;花瓣倒卵形,长15-18毫米,基部具短爪,白色,含苞未放时带粉红色;雄蕊20,花丝长短不齐,约等于花瓣之半;花柱5,下半部密被灰白色绒毛,较雄蕊稍长。
果实扁球形,直径在2厘米以上,先端常有隆起,萼洼下陷,萼片永存,果梗短粗。花期5月,果期7-10月。
苹果树修剪:
剪除根蘖
Use secateurs to cut back the 'suckers', which are the unwanted shoots that grow near thebase of the trunk. Remove all of these shoots up to the base of the main canopy of the treeto encourage a good shape.
使用剪枝夹剪除“根蘖”,也就是树干根部附近生长的多余的枝条。将果树根部一直到树冠底部的所有枝条都剪掉,使果树保持良好的形状。
Step 3: Remove dead wood
3.剪掉枯木
Remove any dead, diseased or damaged wood which is flaking or discoloured. Remove thewhole branch if it doesn't have any buds. If it does have buds towards the base of thebranch, make a cut just above an outward facing bud. Angle each cut so rain can drain off thestem rather than sitting on top and rotting the plant.
剪掉任何正在脱落或变色的枯死的,患病的或损坏的枝条。如果没有花蕾的话,将整个枝条都剪掉。如果枝条底部有花蕾,只剪掉向外生长的花蕾上方的枝条。修剪的时候剪刀要保持一定的角度,这样的话雨水会沿着茎部流走,而不会停留在顶部腐蚀植株。
Step 4: Remove crossing branches
4.剪掉交叉分支
To encourage your tree to grow in a vase shape, remove any branches that cross over. Vaseshaped trees not only look more attractive, they help wind pass through the plant whichprevents it catching airborne diseases. Branches that cross may also rub and become infected. Remove these branches at the base, and any other stems that grow inwards rather thanoutwards.
为了让果树长成花瓶的形状,剪掉任何交叉的枝条。花瓶形状的果树不仅外形更漂亮,还可以使通风效果良好,防止感染空气传播的疾病。交叉的枝条还可能互相摩擦,互相感染。从底部剪掉这些枝条以及所有向内生长而不是向外生长的枝条。
