秦皇岛市是我国酿酒葡萄重点栽培地区之一。1999年以来,全市重点推广了提高酿酒葡萄品质的综合技术,并辐射推广到临近省市,取得显著的经济效益。一、改“U”字形叶幕结构为“V”字形叶幕结构长期以来,我国酿酒葡萄产区栽培方式普遍采用双篱壁架式,即“U”字形叶幕结构(四根横梁间距都是50cm,长度相等)。这种架式虽产量高,但由于叶幕开张角度偏小,光能利用率低,致使果穗着色不良,含糖量偏低,不利于酿造高档葡萄酒。“U”字形叶幕结构的改造,即将原来长度都是50cm的四根横梁,改为横梁长度自下而上分别为20cm、55-60cm、90- Qinhuangdao City is one of the key cultivation areas of China’s wine grape. Since 1999, the city has focused on promoting the integrated technology of improving the quality of wine grape and has promoted the radiation to neighboring provinces and cities and achieved remarkable economic benefits. First, to change “U ” glyph leaf curtain structure “V ” glyph leaf curtain structure For a long time, the cultivation of wine grape growing areas commonly used double-headed ledger type, that is, “U ” shaped leaf curtain structure (Four beams are 50cm spacing, length equal). Although this type of rack production is high, but due to the opening angle of leaves is too small, low utilization of light energy, resulting in poor coloring ear, sugar content is low, is not conducive to brewing high-end wines. “U ” glyph leaf curtain structure of the transformation, the original length of the original are 50cm four beams, beam length from bottom to top were 20cm, 55-60cm, 90-
