为了研究不同滴灌灌水量对哈密成龄大枣生长的影响，在灌水次数相同的情况下，设置了5个灌水处理，观测了全生育期内大枣的生长指标（新稍长度、新稍茎粗等）。结果表明，在一定的范围内，各个生长指标都随着灌水的增加而增加。综合考虑在本试验条件下，滴灌哈密大枣的灌溉定额为720~780 mm较为适宜。

To study the influence of different amount of drip irrigation on the growth of Hami mature jujube, 5 irrigation treatments were set in the same irrigation times, the new little length and the new little stem diameter of jujube were observed in its growth period. The results showed that: within a certain range, the growth indexes were increased with increasing irrigation. Considering 720-780 mm was more appropriate under the test conditions, drip irrigation the Hami grape irrigation quota.
