从2000年开始,我们在春暖式大棚杏树栽培中,运用合理的整形修剪与控冠综合技术,成功地把树高控制在1.5～1.8m,达到了树形紧凑、结构合理、树势健壮的效果,使其完全适应于大棚生长环境,解决了棚栽杏树通常存在的枝条徒长、树冠郁闭、结果外移、不能持续稳产等突出问题。下面简要叙述整形修剪与控冠的几项关键技术。1 先促后控,当年成形在整形和肥水条件满足的基础上,选用一级苗春季定植,定植后用地膜覆盖树盘。定干高度5Ocm,萌芽后选2～3个新梢培养第1层主枝,当主枝新梢长至40cm时,及时摘心,促发二次枝,二次枝延长头长到30cm时再次摘心,促发分枝。
Since 2000, we have successfully controlled the height of the tree at 1.5 ~ 1.8m in the apricot cultivation of spring warmth greenhouse using the reasonable technology of plastic pruning and crown control to achieve a compact tree structure, reasonable structure and robust tree structure Effect, so that it fully adapted to the growing environment of greenhouses to solve the shed planted apricot usually exist branches long, canopy canopy, the results of relocation, can not be sustained and stable and other outstanding problems. The following briefly describes the plastic trim and crown control of several key technologies. 1 first to promote control, then forming in the shaping and fertilizer and water conditions to meet the basis of the selection of a spring seedling planting, planting with plastic film tree cover. Set the dry height of 5Ocm, after the bud selection of 2 to 3 shoots to cultivate the first layer of the main branch, when the main branch of the new shoots grow to 40cm, in time topping, to promote the secondary branch, the secondary branch extension head length to 30cm , Triggering branches.
