摘　　要：灌溉水是设施葡萄栽培生产过程中唯一的水分来源。随着设施栽培面积的不断增加,设施栽培对水分的需求越来越大,但不合理的灌水不仅会影响葡萄果实品质和产量,还会造成水资源浪费。为了明确设施葡萄水分需求特点,该数据整理了2019年设施葡萄‘87-1’全生育期内茎流速率日变化量,以及不同生育期(萌芽至花期、幼果发育期、果实转色期、果实成熟期)茎流速率日变化量。数据表明全生育期内茎流速率日变化最大值出现在10:30,而最低值则出现在23:30;幼果发育期茎流速率峰值明显高于其他生育阶段茎流速率峰值。用户可以参照年份对这一数据进行检索。辽宁省设施葡萄全生育期内水分需求特征检测数据集的建立与共享,能够为设施葡萄科学、合理、精准灌溉提供数据基础,同时为节水农业的发展提供了理论依据。Irrigation water is the only water source in the process of grape cultivation and production in greenhouse.With increasing area of protected cultivation,the demand for water in protected cultivation is increasing.However,improper irrigation will not only affect the quality and yield of grapefruit,but also cause a waste of water resources.In order to clarify the characteristics of water demand of protected grapes,the daily variation of stem flow rate during the whole growth stages of grapes,and the daily variation of stem flow rate during different growth stages(budding to flowering stage,fruit developmental stage,fruit coloration stage,mature stage)of grapes were collected in 2019.The data showed that daily variation of stem flow rate in the whole growth period was the highest at 10:30,and stem flow rate was the lowest at 23:30.The peak stem flow rate of fruit developmental stage was significantly higher than that of other growth stages.Researchers can retrieve data on the characteristics of it by survey year.The establishment and sharing of water demand characteristics detection dataset in the whole growth stages of grapes in Liaoning Province can provide a data basis for scientific,reasonable,and accurate irrigation of grapes in greenhouse,and provide a theoretical basis for the development of water-saving agriculture.
