The shortage of water resources, the serious harm soil salinization and large loss nitrogen caused by excessive application fertilizer are main factors restricting sustainable development agriculture in irrigation areas. Based on this factor, saline area needs to find a improvement method that can keep restrain salt, increase production under condition reducing amount application, which is great practical significance for promoting technology high stable grain yield. In paper, physical chemical properties, temporal spatial dynamic distribution water, salt content, sunflower yield use efficiency Hetao were studied means field experiment numerical analysis, mechanism regulation effects different amendments revealed. results showed biochar treatment group significantly reduced pH conductivity, effectively inhibited accumulation soil, increased organic matter content nutrient such as total nitrogen, available phosphorus potassium. porous structure enhances soil’s retention capacity reduces evaporation. combination carbon not only but also prevented from moving surface, further optimizing environment. terms crop growth yield, treated with combined best performance sunflowers, rapid plant height growth, lush leaves, highest leaf index. overall momentum was stronger than other groups.
