Abstract The experiment on afforestation with drip irrigation for five years showed that compared with flooding irrigation the water-saving technology of drip irrigation can save water more than 70%; the survival rate of nursery stock can be 93.4% and the survival rate of young trees can be 96.2%; also the annual growth of the nursery stock can be more than 40 cm. Five years later, the amount of accumulating sand can be 0.58 m3 per tree. It was proved that the drip irrigation technology has feasibility and importance for afforestation in Gobi and sand dune areas, and the popularizing of the technology by adjusting measures to local conditions is a new approach for controlling sand and improving eco-environment in the arid desert area of western China.
