摘要
根据前人研究成果和葡萄生长发育特点,选用初霜日、生长季活动积温、采前两月水热系数和成熟月直观降水量4个气候指标,分析浙江生产优质葡萄二次果的气候适宜度。结果显示,浙江大部分地区都具有生产优质葡萄二次果的气候条件,但葡萄二次果应在8月10日之前萌芽,11月20日之前采收。在8月20日-9月20日、9月20日-10月20日和10月20日-11月20日的3个时段中,不同地区适宜生产优质葡萄二次果成熟的具体时段不同。根据时段的多少可将浙江省二次果生产区域依次分为：Ⅰ级区,杭州、金华、衢州,有3个时段的水热环境相同,都适宜生产优质葡萄二次果;Ⅱ级区,丽水、湖州、嘉兴、宁波,有两个时段的气候条件适宜生产优质葡萄二次果;Ⅲ级区,绍兴、舟山,有一个时段的气候条件适宜生产优质葡萄二次果;Ⅳ级区-不适区：宁波、台州、温州3地气候条件不适宜生产优质葡萄二次果。
Based on previous studies and characteristics of grape growth and development, the four climatic regionalization indexes: first frost date, active accumulated temperature in the growth period, hydrothermal coefficient of two months preharvest and precipitation in mature month, were calculated to analyze the agroclimate suitability for producing high quality second berry of grape in Zhejiang. The results showed the second berry should be sprout before August 10 th, and mature before November 20 th. The three suitable periods: Aug. 20 th to Spt. 20 th, Spt. 20 th to Oct. 20 th and Oct. 20 th to Nov. 20 th, which for second berry mature were different in different regions. According to the number of suitable periods, Zhejiang region would be divided to four zonings, which have different climate suitability for producing high quality second berry. The first zoning, which includes Hangzhou, Jinhua, and Quzhou, has three suitable periods for producing high quality second berry. The second zoning, which includes Lishui, Huzhou, and Jiaxing, has two suitable periods. The third zoning, which includes Shaoxing and Zhoushan, has one suitable periods. The fourth zoning, which include Ningbo, Taizhou and Wenzhou, unsuitable for producing high quality second berry of grape.
