The invention discloses a production method of distiller's grain fermentation liquid fertilizer specially applied to roxburgh rose. The distiller's grain fermentation liquid fertilizer is prepared bythe step of evenly mixing 50 to 80 parts of distiller's grain fermentation extracting solution, 0.5 to 1 part of microelement, 5 to 10 parts of seaweed meal, 5 to 10 parts of natural active organism,2 to 5 parts of potassium bicarbonate, 2 to 5 parts of natural active organism and 2 to 5 parts of natural surface active agent. A preparation method of the distiller's grain fermentation extracting solution comprises the steps: evenly stirring 50 to 80 parts of distiller's grain, 50 to 150 parts of rice washing water, 1 to 2 parts of EM microflora fermentation liquid and 0.5 to 1 part of sugar, performing composting fermentation at the room temperature to obtain a distiller's grain fermentation material, stirring and extracting through a sodium carbonate water solution, filtering and performing evaporation and condensation on obtained filtrate until the density is 1.1 to 1.2 to obtain distiller's grain fermentation extracting solution. The distiller's grain fermentation liquid fertilizerdisclosed by the invention has a good use effect, meanwhile can effectively prevent pest and disease damage to the roxburgh rose and is high-efficiency environment-friendly liquid fertilizer.

The utility model discloses a full-sealed oil-immersed high-capacity power transformer, which relates to the technical field of transformers and comprises an oil tank, a tank cover is mounted on the top surface of the oil tank, cooling components are assembled on two sides of the top surface of the tank cover, and an oil pump is mounted above the tank cover. The louver adopts a gap type structure and a stepped inclined shape, heat in the radiating fins can be smoothly radiated outwards through gaps among the gap type structures by the aid of the gap type structure, and the stepped inclined shape guides an air flowing path, so that the heat in the radiating fins can be radiated outwards by the aid of the gap type structure regardless of blowing of external natural wind. The air can smoothly penetrate through the protective cover along the inclination angle of the shutter and fully flow through the heat dissipation fins when the transformer is in a power-off state or is in air convection caused by heat dissipation of the transformer, and meanwhile, most dust is effectively blocked through the shutter, so that air circulation can be guaranteed, and most dust can be blocked.
