我省苹果树因整形修剪不当,主从不明、结构失调、枝多头乱、冠内郁闭,造成幼树适龄不结果,盛果期产量低而不稳。针对这些问题,提出以下改进意见,供果农参考。 一、定干高度。目前有些果园片面理解低干矮冠的提法,在50—70厘米处定干,使下部主枝过低,造成果实垂地,降低品质,同时管理也不方便。根据我国具体情况,定干高度应以1米左右为宜。 二、干高及整形带下新梢处理。干高(地面距第一主枝)以50厘米左右为宜。过低影响冠下通风
Apple trees in our province due to improper pruning plastic, the main unknown, structural disorders, branches and more turmoil, crowned canopy crown, resulting in young age does not fruition, fruit yield low and unstable. In response to these problems, put forward the following improvements for reference for farmers. First, set dry height. At present, some orchards unilaterally understand the formulation of low dry dwarf crown, dry at 50-70 centimeters, so that the lower part of the main branch is too low, causing the fruit hanging down, reducing quality, while managing is not convenient. According to the specific situation in our country, a fixed height of 1m should be appropriate. Second, dry high and plastic band under the shoot processing. Dry high (the ground from the first main branch) to about 50 cm is appropriate. Too low impact under the crown of ventilation
