上海是个酿酒葡萄发展的新区,从1972年开始引种,1976年建立原料基地,栽培面积逐年上升,至1984年曾发展至近800亩,主栽品种为北醇、北红和少量白羽。近几年原料基地的种植面积逐年下降,至今已不足100亩。下降的主要原因是北醇酿制的葡萄酒质不佳,白羽产量低,栽培性差,种植单位管理成本历年加大,但经济效益不高,管理粗放,品质下降,恶性循环,必自然淘汰。而酒厂也就避近求远,从山东
Shanghai is a new area for the development of wine grapes. It was introduced from 1972 and the base of raw materials was established in 1976. The area of cultivation rose year by year and reached nearly 800 mu in 1984. The cultivars are Beiol, Beihong and a few white feathers. In recent years, the planting area of raw material base has been declining year by year, so far it has less than 100 mu. The main reason for the decline is that the quality of wine produced by Bei alcohol is poor, the yield of white feather is low, the cultivation is poor, and the management cost of plantation has been increasing over the years. However, the economic benefits are not high, the management is extensive, the quality is deteriorated and the vicious circle is eliminated. The winery also seek a closer look, from Shandong
