辽宁省苹果矮化栽培始于1965年,目前已发展到50余万株。这些矮化苹果树,过去大多数都沿用乔化基部三主枝邻近半圆形及其修剪方法,因而骨架大、长枝多、生长旺、结果晚,在密植条件下,很快就全园郁闭而不能充分发挥矮化苹果树早结果、早丰产的增产潜力。为了适应矮化苹果栽培发展的需要,就必须对现行树形和修剪技术加以改革,根据矮化树的特点,采用新的矮化树形及其相应的修剪技术。
Liaoning Province, dwarf apple cultivation began in 1965, has now developed to more than 500,000 strains. These dwarf apple trees, most of the past are used Qiaohua base near the three main branches of the semicircle and pruning method, which skeleton, long branches and more growth, the result is late, in close planting conditions, and soon the whole park Candelabrum can not give full play to the early results of dwarfing apple trees, yield early yield potential. In order to meet the needs of dwarf apple cultivation and development, we must reform the current tree and pruning techniques, according to the characteristics of dwarfing trees, the use of new dwarf tree and its corresponding pruning technology.
