为使幼龄果树提早结果、早期丰产,许多地方的果农采用了拉枝开角措施。但是,苹果、桃、杏等果树拉枝开角后,枝条背上往往会冒出大量的直立旺梢,再一次造成树形紊乱,若任其生长,就会使延长头趋于衰弱,内膛光照恶化,侧生部分难以培养,加重冬剪难度;如果疏去,在剪口处隐芽又萌发,有机营养消耗很大。因此,拉枝开角后,若能够及时转化,才有利于边整形边结果。 In order to make young fruit trees early results, early high yield, fruit growers in many parts of the adoption of open-angle opening measures. However, apple, peach, apricot and other fruit trees pull branches open angle, branches often emerge a large number of upright shoots, once again caused the tree disorder, if allowed to grow, it will make the extension of the head tends to weaken, within Bore light deterioration, lateral growth is difficult to cultivate, increasing the difficulty of winter cut; if the sparse to go, at the nick hidden bud germination, organic nutrition consumption. Therefore, pull the branches open angle, if they can be converted in time, it will help edge the edge of the results.
