A straw interlayer added to soil can effectively reduce salinity effects on plant growth, however, the of moisture, salt and microbial community composition growth under a are unclear. rhizobox study was conducted investigate role thickness migration, composition, as well root in sunflower. The included four treatments: Control (no interlayer); S3 (straw 3.0 cm); S5 5.0 S7 7.0 cm). Straw treatments increased moisture by 8.2%-11.0% after irrigation decreased content bud stage 0-40 cm soil. Total length, total surface area, average diameter, volume number tips sunflower plants were higher than control, highest treatment. This stimulated ascribed abundance Chloroflexi Verrucomicrobia bacteria with interlayer, which 55.7 54.7%, respectively, Addition 5 is practical environmentally feasible approach for improving saline-alkali
