Abstract Ningxiaisone of the provinces with the fastest developmentof direct seeding rice，and the current direct plantingarea has reached more than 98%of theplantingarea of rice.Irrigation afterdrydirectseeding is the main planting method of direct seeding rice in Ningxia，accounting for more than 70% of the area of direct seeding rice.Dry direct seeding with shallow soil cover is a kindof water supply after drydirectseeding，which has theadvantages of watersaving，seedsaving，highyield，stableyieldandqualityimprovement.Inorder toprovidetechnologicalsupport fordirectriceplanting inNingxia，thekeytechnological points fordrydirect plantingofriceundershallow soil cover are introduced，such as land preparation，fertilizeroperation，seed preparation，sowing，water layer management， weeding， pest control and harvest.
