中文摘要：

以贺兰山东麓酿酒葡萄主栽品种＂赤霞珠＂为试材,研究了滴灌条件下灌水周期对酿酒葡萄生长发育、产量及品质的影响,以及不同灌水周期下土壤水分动态变化。结果表明：灌水周期为8d处理显著提高新梢长和SPAD值,而灌水周期为6d处理促进养分积累,产量相比灌水周期为4d处理增产29.65%,同时该处理降低总酸、单宁含量,总酚较高;不同灌水周期下土壤水分运移规律明显,侧渗区域主要集中在20~50cm根区活动范围。

英文摘要：

Main cultivar of wine grape‘Cabernet Sauvignon＇were taken as experimental materials at the eastern foot of Helan Mountain,the effect of irrigation cycle on the growth,development,yield and quality of wine grape under drip irrigation were studied,as well as the dynamic changes of soil moisture under different irrigation cycle.The results showed that,irrigation cycle with 8days increased shoot length and SPAD value significantly,irrigation cycle with 6daysincreased nutrient accumulation and yield increased by 29.65%compared with the irrigation cycle of 4days,at the same time,the contents of total acid and tannin decreased,and the content of total phenols was higher.The law of soil water movement was obvious under different irrigation cycle,the lateral infiltration area was mainly concentrated in the 20-50 cm of activity range by root zone.
