我县小观大队栽培梨树有近百年的历史。过去,该队的梨树是圆头形,鞭杆枝过多,内膛小枝枯死,果子结在外围,单株产量低。以后改为盘状形,没有中央领导干,三大主枝平面分布,修剪量大,冒条多,结果枝少。年年推平头重剪,秋后一树条子,产量低而不稳。经反复实践,他们把老梨树改造成盘状挺身形(题图),此为比较理想的树形。这种树形是在骨干枝背上的适当位置选3—4个徒长枝培养成假中干。然后将假中干上的徒长枝缓放培养为侧枝、结果枝或枝
Small County Brigade cultivation pear has nearly a hundred years of history. In the past, the team pear is round-shaped, whip sticks too much, the inner branchlets withered, fruit knot in the periphery, low yield per plant. After the change to a disk-shaped, there is no central leadership, the three main branches of the plane distribution, pruning a large amount, taking more than a few branches. Push the head every year, heavy shear, autumn a tree sliver, low yield and instability. After repeated practice, they transformed the old pear into a plateau shape (Figure), this is the ideal tree. This tree is in the backbone of the back of the branches in the appropriate location to pick 3-4 apples grow fake dry. And then leave the dry branch of the growth of slow cultivation for the collateral, the results of branches or branches
