The invention provides a method for planting multiple varieties of forage grass under a walnut forest, and belongs to the technical field of agricultural planting. The method comprises the following steps: (1) soaking forage grass seeds in warm water and a selenium solution in sequence, and drying to obtain pretreated forage grass seeds; (2) mixing the pretreated pasture seeds obtained in the step (1) with a coating agent to obtain coated pasture seeds; and (3) mixing the pasture seeds subjected to coating treatment obtained in the step (2) with crushed walnut leaves, and then sowing the mixture under a walnut forest. According to the method, the grass seeds are pretreated and coated in the warm water and the selenium solution, so that the germination performance and the growth performance of the grass seeds can be remarkably improved. In addition, before the grass seeds are sown, the grass seeds are mixed with the crushed walnut leaves, the crushed walnut leaves can provide appropriate environmental conditions and nutrient substances for germination of the grass seeds, and the yield of the grass can be further increased.
