Abstract
A method for micro-ridge mixed-sowing cultivation of rice includes: S1: draining away water at the maturity stage of the preceding crop until reaching a state allowing a harvester to operate; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble to form a rhizosphere layer for rice growth; S3: trenching the field to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and fall the seed-fertilizer-soil compounds on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, and the seed-fertilizer-soil compounds are obtained by thoroughly mixing rice seeds, chemical fertilizers and soil at a mass ratio of 6 to 14:50 to 70:6,000 to 10,000.
