Abstract
A method for micro-ridge mixed-sowing cultivation of dryland crops includes the following steps: S1: cleaning ditches and draining away water in dryland; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble; S3: trenching the dryland 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 allowing the seed-fertilizer-soil compounds to fall on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, an ecological depression is formed between adjacent ecological ridges, and after sowing, an irrigation is carried out, including: draining water shortly after the irrigation, without leaving a water layer in the field.
