| 为了探究控水滴灌下水分亏缺对酿酒葡萄水分利用效率、产量及品质的影响，分析品质与产量构成因素间的典型相关性，进行了不同生育期水分调控滴灌试验。结果表明：浆果膨大期轻度水分亏缺减产幅度达60%左右，WUE降幅达38%，果实可溶性固形物的含量降低7.0%，且不利于葡萄后期的自然降酸，对酿酒葡萄负面影响最大；着色成熟期轻度水分亏缺可使总糖含量提高22.4%，酸含量降低9.3%，并能提高单宁含量。通过典型相关分析得出：单穗粒数与可溶性固形物、花色苷含量呈正相关，单株穗数与单宁含量呈负相关。 |

| In order to explore the influence of water dificit to water use efficiency (WUE), yield and quality of wine grape under the trickle irrigation, typical correlation between quality and yield components, carried out the experiment of water control trickle irrigation in different growth stage. The results showed that: The yield would be decreased about 60% by mild water deficit in berry expansion stage, WUE would be reduced 38%, the fruit soluble solids content would be reduced 7.0%, and was no useful to the natural decrease of the acid content of grape in late stage, and the negative effect was maximum to wine grape. The mild water deficit in the coloring and mature stage, the total sugar content would be increased 22.4% and the acid content would be decreased 9.3%. Through the canonical correlation analysis obtained that: It has showed a positive correlation between the grape numbers of single cluster with the soluble solids content and anthocyanin content, while has showed a negative correlation between the grape numbers of single cluster with the tannin content. |
