The study of influence on water-salt transportation under saline drip irrigation

Through 3salinity gradients (13.2g / L, 23.2g / L, 27.2g / L) saline drip irrigation, The results showed: in the surface and deep, the peak amount of salt accumulated is about 50cm away from the emitter, and the middle layer varied from 25cm ~ 50cm; in the soil below 20cm, a positive correlation between the salinity distribution and water distribution in 13.2g / L and 23.2g / L treatments, and negative correlation in 27.2g / L treatment; the salinity under drip irrigation conditions are very good on the surface of salt leaching effects, sand for the development of vegetation water to provide support. The result will provide theoretical support for the development of drip irrigating sand vegetation with salty water.
