1. A method for a micro-ridge mixed-sowing cultivation of dryland crops, comprising the following steps:

S1: cleaning ditches at a maturity stage of a preceding crop and draining away water in a dryland;

S2: harvesting the preceding crop, leaving standing stubble, smashing stalks of the preceding crop to obtain smashed stalks, and then spreading the smashed stalks on the standing stubble;

S3: trenching the dryland to form a plurality of ecological trenches, composed of a trench body, side cracks, and bottom mud; and

S4: flattening the standing stubble and the smashed stalks on a seedbed surface to form an underlying surface; molding seed-fertilizer-soil compounds into a ridge shape and falling the seed-fertilizer-soil compounds on the underlying surface to form a plurality of ecological ridges, wherein ecological ridges of the plurality of ecological ridges are formed between adjacent ecological trenches of the plurality of ecological trenches, an ecological depression, composed of a sponge layer, topsoil layer, and ecological cracks, is formed between adjacent ecological ridges of the plurality of ecological ridges, sowing, and after sowing, an irrigation is carried out once in a manner, wherein the manner comprises: draining irrigation water shortly after the irrigation, without leaving a water layer in a field; wherein the seed-fertilizer-soil compounds are obtained by thoroughly mixing soil with seeds of the dryland crops and chemical fertilizers.
