新梢摘心是葡萄夏季修剪不可缺少的工作,在一定肥水条件下,对新梢摘心,并对副梢进行及时处理,有利于葡萄质量和产量的提高,同时亦可达到葡萄“省工”栽培的目的。在以往的研究中,着重于鲜食品种,尤以巨峰为多,对酿酒葡萄研究较少,本研究是“酿酒葡萄省工栽培”的一个内容,以期探讨除,果穗以上副梢采取单叶摘心,破除腋芽,顶端留2副梢的基础上,在花前不同时期进行结果枝摘心,和不同摘心强度的试验,以确定不同酿酒葡萄品种摘心时期、摘心强度对座果率的影响。1 材料方法1.1 材料:3年生霞多丽（民族化工基地）;3
Shoot topping is an indispensable work in the pruning of summer grapes. Under certain fertilizer and water conditions, the topping is performed on the shoots and the secondary shoots are timely processed, which is beneficial to the improvement of the quality and yield of the grapes, the goal of. In previous studies, the emphasis was placed on the varieties of fresh food, especially Jufeng, and less research on wine grapes. This study is a part of the project of “saving and cultivating wine and grape” Topping, removing the axillary buds, the top left two pairs of shoots on the basis of the results in different periods before anthesis prick, and different inoculation strength of the experiment to determine the different wine grape during the period of, the pinching strength of the rate of fruit set. 1 Materials Method 1.1 Materials: 3 years Chardonnay (National Chemical Base); 3
