Experiment on application of micro-saline water alternative irrigation in north-west China

Due to shortage of fresh water in north-west China,exploitations of saline water become very important for mitigating water shortage of farmland irrigation.In order to research the effect of water and salt transport rule and crop yield under saline water irrigation,the plot experiments under different saline water alternative irrigation in north-west China was conducted,and the saline water irrigation happened in the middle growth stage of corn.The results showed that the soil moisture can meet the demand of corn growth in accordance with farmers' irrigation experiments.Under the effect of leaching and evaporation,the soil salt content was lower than pre-sowing.The decrement of yield was less than 10% under the irrigation with 3 g/L and 5 g/L of saline water.
