This invention discloses a method for rapidly improving the productivity of degraded grassland, relating to the field of grassland ecological restoration technology, and is mainly applicable to degraded Leymus chinensis meadow steppes in temperate continental semi-arid climates. The method involves a combined root-cutting and fertilization operation on the target degraded grassland, followed by enclosure and management to complete the restoration. During the regreening period of the degraded grassland, 1-2 rows and oblique root cuts are performed at 6-10 day intervals. Fertilization involves applying 45-60 kg / mu of granular or mixed organic fertilizer. Granular or mixed organic fertilizer is applied 3-5 days after root cutting, and enclosure and management are implemented for 2-2.5 years with a complete ban on grazing. This invention is simple to operate, effectively promotes the natural recovery of Leymus chinensis communities, rapidly improves the productivity of degraded grasslands, meets the restoration needs of degraded Leymus chinensis meadow steppes in temperate continental semi-arid climates, and is easily scalable and applicable.
