| Nowadays,water shortage has become a worldwide problem,freshwater resources shortage seriously influences the development of agriculture in our country ,it is of great importance to exploit and develop the brackish water to irrigate.China has abundant salt water resources, however, the traditional method of improving salt-alkali field need flushing pressure salt with many freshwater,meanwhile, the flushing can cause the rising of the underground water level, and it can cause new soil deposited salt problem,so this method undoubtedly exists application crisis, And under these conditions,what measures should take to develop and utilize the saline-alkali become a new research project.Although many scholars had already done a lot of successful effectively research on the usage of brackish water ,but many problems need to be further studied.Brackish water drip irrigation can ease the tendency of water shortage,meanwhile, choosing the salt-tolerant crops not only can save water, but also can increase output.this paper regards this as a starting point, using the underground brackish water to make irrigation tests under different salinity conditions and confirming the movement of water and salt under different salinities brackish water drip conditions. This paper on the basis of domestic and international brackish water ground irrigation research achievement, adopting the method of the combination of laboratory analysis and indoor and outdoor experiment to explore the impact of brackish water drip irrigation for the state of Water and salt migration of Jujube soil root zone, considering the actual condition that the local climate drought and water shortage to the growth status and jujube fruit production under the effects of water stress and salt stress, obtainthe effect of water saving and production increasing at the same time won't produce salinization harm and eventually select the best test plan.
