Abstract: Aiming at the problem that it is difficult to indrought in Xinjiang due to dry climate and water shortage, a wind and solar hybrid air catching system was designed to collecte the wet air formed by transpiration of plants and evaporation of irrigation in the field. The collection unit by aerodynamic was designed,the system feasibility was demonstrate by compared different condensation methods, the installation position of the condensing unit was determined to be 80 cm underground.The modes of the system was established by 3DMAX and the physical object was made according to it.The water collecting irrigation program was compiled on the single chip microcomputer by using C language,and the air water collection under the ideal state was calculated by assuming the ideal data. Finally, the experimental data were measured, and the reasons for the gap between the actual water collection and the theoretical water collection were analyzed. The results indicate that the actual water collection of the system is 57% of the theoretical water collection，it has good development prospect in the field of agricultural irrigation and air water collection in no man's land.
