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.
