纺锤形,特点明,一根粗干长正中。单轴主枝十二三,螺旋排列插空生。上小下大宝塔形,树形很象一雪松。苹果纺锤树形已基本为广大果树管理者所了解应用;因密植园激增而此种树形广为应用,由于受传统整形套路的影响和实际操作中的失误,许多园片的树形依旧相当混乱,归纳总结,有五个误区,现逐一说明并提出对策。 1.中干细斜不壮。中干是纺锤形树体唯一永久性骨干组分,它必须维持较直立,粗壮。但是生产中往往因下层留枝太多,或人为弯曲拉倒中干,使中干不直不壮,无法建造规范的纺锤
Spindle-shaped, characterized by a rough middle length. Twelve one-axis main branch, inserted spiral arrangement of empty students. On the next big pagoda-shaped tree like a cedar. Apple spindle tree has been basically for the majority of fruit tree managers to understand the application; due to the proliferation of dense plantations and such tree-wide application, due to the impact of the traditional shaping routines and the actual operation of the mistakes, many of the tree is still the same segment tree Confusion, summed up, there are five errors, one by one to illustrate and propose countermeasures. 1. The dry stem is not strong. Stem is the only permanent backbone of the spindle-shaped tree, which must remain relatively upright and stout. However, the production is often too much because of the lower branch, or artificial bending down in the dry, so dry is not strong, can not build a standard spindle
