母树选择年龄较小的鸭梨树,进行高接换头,为了达到迅速恢复生产、提高效益的目的,对高接树除了进行肥水管理和病虫害防治以外,重点采取以下技术措施: 一、除萌。对丛生萌蘖只保留一根壮条并在生长到30厘米左右时掐尖以外,其余全部去除。二、新梢保护。新梢长出以后要特别防止被风吹断,因此当接芽长到20厘米以上时要及时绑扎支棍用以固定新梢。三、促发分枝。促发分枝的目的是迅速扩冠。当新梢长到30厘米以上时,及时掐尖促发分枝,其下部可发出7~10根副梢,最多可发出13根。一个月后二次枝可达20厘米以上。此阶段更要及时绑缚巩固,防止被风吹断,前功尽弃。
In order to achieve the goal of rapid recovery of production and improvement of benefits, the selection of the female tree is carried out with high replacement. In addition to fertilizer and water management and pest and disease control, the following measures are taken: 1. . Sprouting on the clusters only retain a strong spur and grow to about 30 cm pinch point, the rest of all removed. Second, shoot protection. After the new shoots to be especially to prevent the wind from blowing off, so when the bud to grow more than 20 cm in time to tie the stick to fix the shoots. Third, triggering branches. Promote the purpose of the branch is to quickly crown. When the new shoots grow to more than 30 cm, timely pinch pointed trigger branches, the lower part can issue 7 to 10 Vice shoots, up to issue 13 root. A second branch up to 20 cm after a month. This stage must be more timely bondage consolidation, to prevent being blown off, come to naught.
