大棚油桃果实采收后需要恢复树势,并要考虑下年的花芽质量和树体结构,因此,这一阶段的土肥水管理、病虫害防治、整形修剪显得至关重要。一、采后修剪。结果期在单位面积内树体已形成,空间基本占满,但撤棚后与露地有同样的生长时间,如果不认真修剪,势必造成严重郁闭。而此时外界温度偏低,大棚桃有个缓长期,正是进行适度重剪的好时期。1、常规修剪法。①疏除细弱枝、病虫枝、枯死枝、下垂枝、过密枝和外围过旺枝,打开光路,有利于花芽分化。②回缩枝组,即把原来由4～6个以上结果枝组成的枝组回缩成2～4个枝,并对组内旺枝留2～4芽短截,促发新枝,培养成新的枝组。③树冠下部大型枝组结果后可能下垂,要撑、顶使其恢复长势。④密植往
Therefore, it is very important to manage soil and fertilizer, pest and disease control and plastic pruning in this stage. First, post-harvest pruning. The results of the tree in the unit area has been formed, the basic space occupied, but after shed shed and open the same growth time, if not carefully pruned, is bound to cause serious canopy closure. But at this time the outside temperature is low, peach peach has a long period, it is a good time to moderately cut. 1, conventional pruning method. ① sparse fine branches, pest branches, dead branches, drooping branches, dense branches and the surrounding excess branches, open the light path is conducive to flower bud differentiation. ② retraction Zhizu, that is, the original group consisting of more than 4 to 6 branch branches retracted into 2 to 4 branches, and the group branches left 2 to 4 buds short stub, trigger new branches, cultured into New branch group. ③ large branches under the crown after the results may hang down, to support, top to make it recover. ④ dense planting
