According to the technical scheme, the problems that the wheat-wheatgrass distant filial generation powdery mildew resistance screening period is long, the workload is large, accurate screening cannot be conducted in early generations, and the breeding difficulty is large in the prior art are solved.

The invention discloses a composite ecological seed bag for restoration of a degenerated natural warm grassland and a reseeding method thereof, and belongs to the technical field of ecological restoration, the composite ecological seed bag for restoration of the degenerated natural warm grassland is composed of leguminous grass seeds and gramineous grass seeds, the leguminous grass seeds are medicago falcata, and the gramineous grass seeds are grassy grass seeds. The gramineous grass seeds are selected from at least two of wheatgrass, elymus dahuricus, awnless brome and new wheat straw; wherein the total mass ratio of the medicago falcata to the gramineous grass seeds is 3: 7 or 5: 5. According to the method, Yili local grouped seeds and dominant grass seeds are all selected for the compound ecological seed bags, the biological invasion risk is avoided from the source, the proportion of the local grouped grass seeds is 100%, and the local grouped grass seeds are highly matched with the local loamy chestnut soil, the altitude of 1200-1700 m and the habitat height of 300 mm or above. Wherein the medicago falcata is high in nitrogen fixation capacity and capable of improving soil fertility, and gramineous grass seeds such as wheatgrass and elymus dahuricus are high in stress resistance, good in compatibility with an original community structure and capable of being rapidly fused into a local ecological system after reseeding.
