Abstract: To study the effect of sediment reclamation of Yellow River on soil salt content and the growth of winter wheat, we carried out a sand-addition experiment [0 kg/m2(CK), 10 kg/m2(NS1) and 20 kg/m2(NS2)] in the coastal saline soil area, and analyzed the changes of soil salt content, soil water and salt dynamics, the growth and yield of winter wheat and other indicators. The results showed that: the particle composition of the Yellow River sediment and the clay saline soil were obviously different, and the fine sand particles in the Yellow River sediment could regulate the particle composition of the clay saline soil; furthermore, the soil salt content decreased with the increasing amount of sediment: compared with CK, the salt content of 0-20 cm layer under NS1 and NS2 was reduced by 45.88% and 60.43% in spring and decreased by 9.32% and 44.46% in autumn; compared with CK, the winter wheat tiller, plant height, shoot biomass and winter wheat yield under NS1 and NS2 were significantly increased (P<0.01), the winter wheat yield of NS1 and NS2 increased by 32.98% and 62.63% , respectively. Therefore, Yellow River sediment can effectively regulate the particle composition of clay saline soil, reduce soil salt content, and promote growth as well as crop yield of winter wheat.
