The invention discloses a method for utilizing a sand culture mode to plant forage grass to consume biogas slurry of a pig farm. The method includes that high-efficiency sewage consumption and fresh grass supply of the forage grass is realized by constructing a waterproof and rainproof sand culture container, laying and pouring sand girt, controlling concentration of the biogas slurry, irrigating the biogas slurry, planting the forage grass and harvesting the forage grass. According to the method, biogas slurry consumption quantity of the forage grass per unit area can be remarkably increased. The forage grass produced by the method has the advantages of high yield, good quality and the like. Land for forage grass production can be greatly reduced by fully utilizing space advantage; by further transforming equipment, controllable and intensive production of high-quality forage grass can be realized, and large-scale production of plant-eating animals is benefitted.
