我县生产的杜康名洒畅销国内外,年产量2500多吨。1990年将扩大到5000吨以上,已成为我县一大经济支柱。杜康酒厂现在每年需要高粱750多万公斤,而本县种植的高粱远不能满足需要,有90%需从东北调进,年调运费4万多元。为了降低酿酒成本,增加农民收入,减轻铁路运输压力,我们从1985年开始筛选适宜酿洒的高粱品种,以促进高粱和酿酒生产的发展。一、品种比较试验和示范1、品种比较试验:1985年从东北、山西等地收集了十个高粱杂交组合:原杂十号、晋杂一号、五号、沈杂三号、四号、622A Dukang produced by my county sprinkled the best-selling home and abroad, with an annual output of more than 2,500 tons. 1990 will be expanded to more than 5,000 tons, has become a major economic pillar of our county. Dukang wineries now require more than 7.5 million kilograms of sorghum each year, while the sorghum grown in the county is far from meeting the needs. 90% of the sorghum needs to be transferred from the northeast and annual transportation costs more than 40,000 yuan. In order to reduce the cost of making wine, increase farmers’ income and reduce the pressure on railway transportation, we started to select suitable varieties of sorghum from 1985 to promote the development of sorghum and wine production. First, the varieties of comparative experiments and demonstrations 1, varieties of comparative test: In 1985 from the northeast, Shanxi and other places collected ten sorghum hybrid combinations: the original hybrid ten, Jin mixed one, five, Shen miscellaneous third, fourth, 622A
