摘要
气象条件是影响葡萄糖分积累的主要环境因素之一。利用酿酒葡萄(赤霞珠)糖分观测数据和相应气象数据研究气象因子对酿酒葡萄糖分积累的影响发现,在酿酒葡萄着色至成熟期,对酿酒葡萄糖分积累影响较大的气象因子是日平均气温、最高气温、日照时数和温湿比。最适于糖分积累的平均气温、最高气温、日照时数和温湿比分别是24.0℃、29.3℃、6.4 h和0.35左右,在小于上述极值点的范围内,糖分日积累量随各因子(值)的增加而增加;在大于上述极值点的范围内,糖分日积累量随各因子(值)的增加而减少。
Weather condition is one of environmental factors influencing the sugar accumulation of wine grapes. Research shows that average air temperature, maximal air temperature, sunlight duration and temperature-humidity ratio are four main weather factors affecting daily sugar accumulation from coloring stage to maturity stage. The daily sugar accumulation of grapes is optimal when average air temperature, maximal temperature, sunlight duration and temperature-humidity ratio are 24.0 ℃, 29.3 ℃, 6.4 h and 0.35, respectively. At the range of less than these values, the daily sugar accumulation increases with these factors, and at the range of greater than theses values, the daily sugar accumulation decreases with these factors.
