XIE Li-xin1,ZHAO Xin1,LI Ping-li1,WU Xi-dong3,XIAO Jian-guo2(1.School of Chemical Engineering and Technology,Tianjin University,Tianjin 300072,China;2.Tianjin Crops Research Institute,Tianjin 300112,China;3.Tianjin Agricultural University,Tianjin 300384,China)  
In this work sea ice melt-water of 0.3%、0.5%、0.7% salinity were used to irrigate corn.The results show that irrigated with the 0.3% water at the rate of 450 m3 per hectare,the crop drought can be reduced,and the corn yield increased significantly,while the rate added to 900 m3 per hectare and 1350 m3 per hectare the output descended.Compared with 0.3% at the rate of 450 m3 per hectare,the corn yield irrigated with 0.5% salinity sea ice melt-water at the rate of 450 m3 per hectare,900 m3 per hectare and 1350 m3 per hectare were reduced at the range of 9.5%~18.4%.When the salinity of sea ice melt-water was 0.7% and the irrigating rate was 1350 m3 per hectare,the corn yield was close to the level of full drought district.Irrigated with different salinity sea ice melt-water,the difference of the corn yield was remarkable.
