The invention discloses a rice micro-
ridge mixed 
sowing cultivation method. The method comprises the following steps: S1, draining water in the mature period of preceding crops until a harvester can work; S2, harvesting the preceding crops, reserving stubbles, smashing 
straw of the preceding crops and then scattering smashed 
straw on the reserved stubbles so as to form 
rhizosphere layers for ricegrowth; S3, performing ditching in the field to form ecological ditches; and S4, flattening the vertical stubbles and the crushed straws on the compartment surface to form a lower 
cushion surface, forming a seed, 
fertilizer and mud compound into a 
ridge shape, enabling the compound to fall on the lower 
cushion surface to form ecological ridges, and forming a plurality of ecological ridges betweenadjacent ecological ditches, wherein the seed, 
fertilizer and mud compound is obtained by uniformly stirring and mixing rice seeds, a chemical 
fertilizer and mud in a 
mass ratio of (6-14):(50-70):(6000-10000). Firstly, the ecological ridges are used as a medium to wrap organisms and vegetative bodies and is heat-insulating, 
moisture-preserving, water-permeable and air-permeable; and secondly, theecological ridges are used as a donor to provide water 
nutrition for 
organism vegetative 
mass. The seeds which are subjected to accelerating 
germination and 
budding in the ridges grow faster than weedseeds in the ridges and outside the ridges, and roots and leaves grow smoothly.
