桃树苗夏季修剪知识大汇总 Summer pruning knowledge collection of peach seedling 对桃树来说：冬剪好比播种定苗，夏剪好比除草灭荒。夏剪做得好，小树利用夏剪(多次摘心)可以尽早形成树冠，提前结果，成年树通过夏剪可以促进花芽分化，节省大量营养。 The peach: winter pruning is like sowing seeding, summer pruning is weeding out shortage. Summer pruning is done well, the trees by summer pruning ( repeatedly pinching ) as soon as possible the formation of crown, early results, adult tree by summer pruning can promote the differentiation of flower buds, save a lot of nutrition. 一、夏剪时期：第一次从6月上中旬开始，主要是控制、利用徒长枝、疏密枝，尤其要疏内膛直立密枝，疏除枯枝。徒长枝根据需要给以剪梢、扭梢等处理抑制旺长，使其转化为结果枝。其他枝条凡长30—40cm的都要摘心，使养分集中到果实的生长发育上去，防止落果。第二次在8月上中旬进行，主要是缓和树势，培养结果枝组，疏剪上部强枝，增加树冠中、下部的光照，促使花芽分化。凡是带有副梢的枝条，留下部1—2个副梢缩剪，同时在留下的副梢长约20cm以上处扪心或扭梢，斜生枝、平生枝还应摘心，继续疏除过密枝条。这次夏剪修剪量不宜过重，以免伤口流胶。 A, summer pruning period: first start from mid June, is mainly controlled by the density, leggy branches, branches, especially to open bore vertical dense branches, thinning branches. Tu Changzhi according to the need to pruning, twisted shoots inhibition of flourishing, make it into a branch of the result. All other branches of 30 - 40cm are pinching, make the nutrients on growth and development of fruit, prevent fruit drop. Second times in the first half of August, mainly is to ease the tree vigor, training branch, trim upper strong branches, increase, lower canopy light, promote flower bud differentiation. All with side shoot branches, leaves 1 - 2 side shoot shear reduction, while in the left side shoot length of about 20cm above in torsion or shoot, Shaki Mie, Hiraki Mie also should continue pinching, thinning dense branches. The summer pruning shear volume shoulds not be too heavy, so as not to wound gumming. 二、夏剪方法 Two, summer pruning method 1、抹芽、除萌。通过抹芽、除萌，可以减少无用的新梢，改善光照条件，节省养料，促使留下的新梢健壮生长，并可减少冬剪因疏枝而造成的伤口。抹芽包括树冠内膛的徒长芽、剪口下的竞争芽，留副梢芽等。除萌是掰掉5cm左右的嫩梢。一般双枝“去一留一”，即在一个芽位上如发生两个嫩梢，留位置、角度合适的嫩梢，掰掉位置、角度不合适的嫩梢。 1, wipe bud, except the adorable. Through sprouting, except the adorable, can reduce shoot useless, improve light conditions, save food,
