In order to study the effects of different irrigation quotas on the growth of red jujube and the dynamic changes of soil moisture under drip irrigation in the Hetian area of southern Xinjiang, four moisture gradients were designed to study the changes of new shoots, photosynthesis and yield under different water gradients, and the soil water content in the whole growth period of jujube was measured by drying method. Jujube trees grew faster at the budding leaf development stage and the flowering and fruit-setting stage. The length and diameter of the jujube new shoots followed the order of W33/667 m²) treatment was more suitable for drip irrigation red jujub growth, with the highest yield (540.56 kg/667 m²) and the highest irrigation water use efficiency (1.29 kg/m³).
