摘要
摘要：气象数据的统计结果显示：天津地区的汉沽、北辰、宝坻、蓟县4个葡萄产区的4—10月活动积温为3580～3700℃，能够满足不同成熟期酿酒葡萄品种对热量的需求；4个产区4—10月份活动积温差距小，无法进行葡萄品种气候区域划分；7—9月份的水热系数值K=I．4～1．8，8～9月份K=1．2～1．6，说明天津地区是酿酒葡萄种植的优良产区。但是7、8月份尤其是7月下旬至8月上旬，全年温度最高，降雨量最大，日照时数最低；高温高湿低光照限制了葡萄品质形成，为病害的发生与流行提供了有利条件，这是品种引进筛选中首先和必须考虑的。
The data analysis result show that four grape areas in Tianjin, including Hangu, Beichen, Baodi, Jixian, where active accumulated temperature from 3 580 to 3 700℃, are the ideal areas for grape planting. The active accumulated temperature can meet the needs of different mature period of wine grape varieties. The difference of active accumulated temperature （April-October） among four grape areas is not significant, so it can＇t be used for climatic regionalization of wine grape varieties in Tianjin. Hydrothermal co-efficient（K） is 1.4 to 1.8 from July to September, 1.2 to 1.6 from August to September in Tianjin region,so Tianjin is a suitable cultivation area of wine grape. But the days in July and August, especially in late July to early August is the highest annual temperature, is the maximum rainfall and the minimum sunshine hours period. The climatic conditions, including high temperature, high humidity and low sunshine limit the formation of grape quality and provide favorable conditions for disease epidemic. Climatic conditions are essential in the selection of wine grape varieties.
