宣化牛奶葡萄的穗形美观、果粒硕大、皮薄肉厚,汁多味甜,为河北省的著名特产,在国内外享有盛誉。但是,宣化葡萄产量极不稳定,存在严重大小年现象。平均每架葡萄产量,有的高达600斤以上(1952年),有的低为50余斤(1978年)。虽然肥水条件较好,但单位面积产量低。1948—1982的35年中,平均亩产仅1,000斤左右。1983年,宣化葡萄总产和单产仍停留在1948年的水平。葡萄生产上存在这些问题的原因,主要是古老的漏斗架有许多缺点,整形、修剪及植株夏季管理等栽培技术比较落后等(详见罗国光、刘丽曦“宣化葡萄栽培现状和发展途径探讨”,葡萄栽培与酿酒,1984,NO 3)。
Xuanhua milk grapes spike beautiful, huge fruit, thin Rouhou, sweet and juicy, Hebei Province, the famous specialty, renowned at home and abroad. However, Xuanhua grapes yield is extremely unstable, there is a serious size year phenomenon. The average yield of each grape, some as high as 600 pounds (1952), and some low for more than 50 kg (1978). Although fertilizer and water conditions are good, but the yield per unit area is low. In the 35 years from 1948-1982, the average yield per mu was only about 1,000 kilos. In 1983, Xuanhua grapes output and yield still remain at the level of 1948. The main reason for these problems in the production of grapes is that the old funnel has many shortcomings. The cultivation techniques such as plastic surgery, pruning and summer management of plants are relatively backward.
