Taked spring corn as the research object, through magnetized water irrigation experiments, the effects of different irrigation amounts (4 200, 4 800, 5 400 m³/hm²) on the distribution characteristics of soil water and salt, dry matter accumulation, yield and growth of maize under the conditions of magnetized water irrigation were studied. The impact of characteristics, to explore the appropriate irrigation volume under the conditions of 3 500 Gs magnetized water, to provide relevant data support for promoting the efficient use of agricultural resources in the Tarim Basin. The results show that magnetized water irrigation could increase soil water content under different irrigation amounts. The soil salt leached effect of 40-60 cm soil layer was better than that of 0-20 cm soil layer. Magnetized water irrigation could promoted corn plant growth and increased yield. Each treatment of magnetized water Irrigated corn yield increased by 2.11%~19.31% compared with non-magnetized treatment; magnetized water 3 500Gs magnetization intensity irrigation 4 800 m³/hm² treatment yields the best, water use efficiency and irrigation water use efficiency reached the maximum, respectively 2.64 and 2.86 kg/m³.Therefore, compared with non-magnetized irrigation, the appropriate amount of magnetized water irrigation could improved the dry matter accumulation of corn ears,which was beneficial to increased the yield and water used efficiency of corn.
