The invention provides a microorganism for improving grassland and application of the microorganism for improving the grassland, the microorganism for improving the grassland comprises Bradyrhizobium japonicum TG101, and further comprises one or more of Brevibacterium tumefaciens TG15, Phyllobacterium tumefaciens TG47 and Enterobacter ludwigii DP20, and the microorganism for improving the grassland further comprises one or more of Bradyrhizobium japonicum TG101, the Brevibacterium tumefaciens TG15, the Phyllobacterium tumefaciens TG47 and the Enterobacter ludwigii DP20. According to the application, novel application of the brevibacterium friariorum TG15, the leaf bacillus dulcis TG47 and the enterobacter ludwigii DP20 is innovatively found, that is, the three bacteria and the combination thereof can promote nodulation of the bradyrhizobium elwardii TG101; the compound microbial fertilizer disclosed by the invention has the functions of greatly improving the nodulation quantity, root nodule diameter and nitrogen fixation capability of lespedeza daurica in the field, and greatly improving the yield, quality and medicinal components of lespedeza daurica.

The invention discloses a method for reducing the infection risk of leeches in golden trevally culture, and belongs to the technical field of aquaculture. The method comprises the following steps: culturing golden trevally in a culture barrel, a cement pool or a net cage, and controlling the daily water exchange capacity to be more than 100%, the pH value of a water body to be 7.8-8.6, the dissolved oxygen to be more than 5.0 mg.L <-1 > and the ammonia nitrogen to be less than 0.2 mg.L <-1 >; the breeding density is reasonably controlled; carrying out polyculture on scatophagus argus in a certain proportion; reasonable bait casting; daily pool inspection and inspection; when the leech infection risk exists, the seawater salinity is adjusted regularly. According to the method, by comprehensively regulating and controlling the breeding environment and taking targeted measures, the infection risk of the golden trevally leeches can be remarkably reduced, leech parasitism is reduced, the breeding efficiency is improved, and the method has good application prospects.
