A Breakthrough Thought for Water Saving and Salinity Control in Arid and Semi-arid Area— Under-film trickle irrigation

Focusing on Xinjiang, a arid and semi arid area, disadvantages and shortcomings of traditional saline soil development and reclamation were analyzed. A breakthrough thought for water saving and salinity control in arid and semi arid area, i.e. under film trickle irrigation, was presented. The advantages in both plastics film mulch and trickle irrigation was integrated in under film trickle irrigation system. The wide application of this irrigation system in northwestern areas has shown that under film trickle irrigation is helpful to improve water use efficiency, to control salinity and to raise yield.
