The phoxinus lagowskii parent fish batch anesthesia device comprises an operation table, a barrel frame is fixedly connected between the two ends of the top of the operation table, an anesthesia barrel is movably connected between the upper end of the barrel frame and the middle end of the top of the operation table, and a net cage is movably connected to the upper end of an inner cavity of the anesthesia barrel. Holding rods are fixedly connected to the upper ends of the two sides of the outer surface of the net cage. Through the arrangement of the operation table and the barrel frame, the anesthesia barrel can be effectively limited and supported, the anesthesia barrel is prevented from sliding off from the top of the operation table in the use process, through the arrangement of the holding rod, the net cage and the anesthesia barrel can be effectively supported and limited, and through the arrangement of the anesthesia barrel, the net cage and the anesthesia barrel can be conveniently fixed. According to the phoxinus lagowskii parent fish anesthesia device, anesthetic liquid medicine needed by batch anesthesia of phoxinus lagowskii parent fish can be contained, air can be conveyed into the anesthetic liquid medicine in the anesthesia barrel through the arrangement of the electromagnetic air compressor, the air guide pipe and the inflation disc, and therefore the content of oxygen in the anesthetic liquid medicine is effectively increased.

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.
