摘　　要：为研究花期喷水与微喷灌技术结合对红枣坐果率、产量、品质的影响,将微喷灌条件下不同喷头架设高度（冠层下、中、上部）、不同喷水时长（20,40,60 min）进行组合试验,得到以下结论：冠层中部喷水60 min的相对湿度比对照显著提高,坐果率比冠层上部喷水、对照显著提高,产量比对照增加80%,各种组合品质没有差异。干旱区对夜开型红枣,在微喷灌的基础上花期每天傍晚树冠中部喷水40~60 min可以显著提高坐果率、增加产量。In order to research the impact of the combination of spraying water at flowering stage and water-saving irrigation technique on fruit-setting and quality of Chinese jujube,the experiment with different height of water jet,including at the low,center,high parts of trees,and different spraying time,including 20 min,40 min,60 min,is carried out.The results show that the relative humidity and fruit-setting ratio of the treatment with spraying in the center part of trees and 60min is remarkably superior than the comparative treatment,its yield is higher than that of comparative treatment by 80%.The differences of jujube quality among different treatments are not notable.It can be concluded that for the nyctanthous jujube,the treatment with spraying 40~60 min in the center part of trees at dusk of flowering stage can increase the fruit-setting and the yield of Chinese jujube.
