中文摘要: 分析了河西走廊酿酒葡萄果径生长和含糖量累积规律。结果发现:果粒生长动态呈抛物线型，有两个明显的生长高峰期。生长关键期出现在7月上旬～8月上旬，生长率占总生长率的64%～78% ；含糖量累积遵循“S”型生长函数。糖份积累关键期出现在8月中旬中期至下旬，这一时期含糖量累积最快，日累积糖量在0.48%～0.84% ，净累积量占累积总量的73%～77% ；影响糖份累积的关键气象因子主要是光温积和气温日较差。日照时间长，气温高，温差大，糖份积累快，含糖量高。建立了葡萄糖份累积气候模型，以此为依据，计算了河西不同气候区含糖量地理分布，为葡萄基地建设和选择不同葡萄品种提供了依据。

Abstract:By analyzing laws of brewing grape fruit growing and contained sugar accumulation,it shows that fruit growing trends parabola has two obvious growing peak value. The growing key time occurs from the first ten days of July to the first ten days of August,whose growing rate is 64—78 percent of total rate; contained sugar accumulation follows “S” function model. The key time of sugar accumulation occurs from the middle ten days to last ten days of August,whose sugar accumulation is fastest,daily accumulation sugar content is 0.48%—0.84%,pure accumulation sugar content is 73%—77% of total accumulation sugar content. The key factors of sugar accumulation are of main light temperature accumulation and daily range of temperature. The longer the sunlight time,the higher temperature,the faster sugar accumulated,the higher the grape contains sugar content. The grape climate model of sugar accumulation is developed and it can estimate sugar content geographical distribution in various climate areas of Hexi corridor,and therefore it can provide scientific basis for grape breeds selection.
