摘要: 水分条件是影响我国酿酒葡萄品质和经济效益的重要因素。在考虑了我国气候特点和酿酒葡萄生长需要的前提下,通过对几种水分指标的比较和分析,认为将酿酒葡萄生长季(4月1日~9月30日)的干燥度(DI=ETC/P)作为我国酿酒葡萄栽培区划的水分指标(区划南界)是适宜的,较其它水分指标确定的区划更符合实际情况。其中DI<1.0为不适宜种植区;1.0≤DI≤1.6为一般种植区;1.6DI时在有灌溉条件下,可以获得较好的葡萄品质。

Abstract: Atmospheric moisture content is an important index affecting the quality and economic efficiency of grapevine in China. With the consideration of our climate characteristics and grapevine growth needs, and based on the comparison and analysis of several atmospheric moisture content indexes, the authors considered that the dryness index (DI=ETC/P) in grapevine growth season (April 1-September 30) could be a proper atmospheric moisture content index for the climatic zoning of grapevine cultivation in China. It was suggested that the areas with DI<1.0, 1.0≤DI≤1.6, 1.6 as unsuitable economical cultivation, general cultivation, best cultivation, and better cultivation with irrigation, respectively.
