The invention discloses a multifunctional stereoscopic desert sand pressing grass growing machine, and belongs to the field of desert grass growing machines. The multifunctional stereoscopic desert sand pressing grass growing machine comprises a rack, a ground wheel train, a straw laying device, a ditching device, a straw pressing and earthing device and a sowing device; a toothed gear rotating shaft is installed on the upper surface of the rack and can rotate in the axis direction of the rack, four or more rows of straw laying rakes are uniformly distributed on the toothed gear rotating shaftin the circumferential direction, and a first transmission wheel is fixedly installed at one end of the toothed gear rotating shaft; the ground wheel train at least comprises two pairs of ground wheels, a second transmission wheel is fixedly installed at one end of one pair of the ground wheels, and the first transmission wheel and the second transmission wheel are in transmission connection through a belt. The multifunctional stereoscopic desert sand pressing grass growing machine has the advantages that the rack is provided with assemblies which have the dual functions of straw laying and grass growing, firstly, through ditching, straw laying and earthing, straw is buried in sand, then sowing is conducted nearby the embedded straw, thus the functions of automatic straw laying, straw burying and sowing are achieved, and then the purposes of laying of a straw checkerboard barrier and sowing are achieved.
