梨树整形一般采取疏散分层形,这种树形比较符合梨树本身的生长特性,干性明显,层次清楚,主从分明,便于培养大冠高产树形。但这种树形容易造成上强下弱,内空外紧,树冠郁闭,结果部位外移,盛果期果重减少,品质下降等弊端,不适于“矮、密、早、丰”栽培,且成形年限较长,整形技术不易掌握。 笔者经过多年实践探索,设计出一种“多主枝低级次螺旋分层形”树形。在湖北随州、
Pear plastic generally take evacuation stratified shape, this tree shape more in line with the growth characteristics of pear itself, dry obvious, clear level, the main from the clear, easy to cultivate large crown tree. However, this tree shape can easily lead to the disadvantages of “weak, dense, early and abundant” cultivation due to the weakness of the upper and lower limbs, the tightness of the outer skin, the closed crown of the crown, the relocation of the result parts, the reduction of fruit weight during the fruit-bearing period, , And forming a longer period of plastic surgery technology is not easy to grasp. After years of practice, the author has designed a “multi-branch low-level spiral sub-layered” tree. Suizhou in Hubei Province,
