梨树定植时选壮苗,施足底肥。定植当年一次性定干,生长季供足肥水,促其营养生长,当年秋季每株树均可抽出2~3个50~100cm长的强枝。 当年冬季不修剪,次年春季萌芽前20天修剪,树形采用纺锤形,不轻易除掉任何一个发育枝,尤其重点利用竞争枝。对选留做中心干延长枝以外的超过50cm的强枝,拉角使其开张75度左右,较长的枝角度要大些。并同时对该枝的侧芽和背后芽目伤,近树干10cm以内不目伤,近枝梢10cm以上的芽不目伤,枝的顶端缓放;不足50cm长但生长较充实健壮的枝不拉角,只目伤,顶端缓放;细弱枝缓放,不拉角,
Pear tree planting strong election seedlings, Shi enough base fertilizer. Colonization that year disposable set, the growing season for adequate fertilizer, promote their vegetative growth, each tree that year can be drawn out 2 to 3 50 ~ 100cm long strong branches. When the winter is not trimmed, the next spring 20 days before the bud pruning, tree-shaped spindle, do not easily get rid of any one of the development of branches, with particular emphasis on the use of competition branches. On the election to do the center of the dry extension of the branches in excess of 50cm strong branches, pull the corner to open about 75 degrees, longer branch angle to be larger. And at the same time on the branches of buds and buds back injury, near the trunk less than 10cm without injury, shoots near the branches more than 10cm not injury, the top of the branches to ease; less than 50cm long growth but robust growth of the branches do not pull Angle, only the head injury, the top slow release; weak branches slow release, no corner,
