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.

The invention belongs to the technical field of soil improvement, and particularly relates to a microbial soil conditioner as well as a preparation method and application thereof. The microbial soil conditioner comprises a compound microbial agent, an organic carrier and an auxiliary additive, the compound microbial agent is prepared from bacillus subtilis, bacillus amyloliquefaciens, paenibacillus mucilaginosus and bacillus licheniformis. By screening microbial strains with a synergistic effect and combining with an optimized organic carrier, the soil conditioner not only can effectively improve the physicochemical properties of soil, break soil hardening and regulate the pH value of the soil, but also can improve the fertility of the soil, promote the growth of crop roots and inhibit the reproduction of harmful pathogenic bacteria in the soil; the use amount of chemical fertilizers and pesticides is reduced. Meanwhile, the preparation method disclosed by the invention is simple in process, relatively low in cost and suitable for large-scale industrial production, and has a wide market application prospect.
