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 relates to a filter press, which belongs to the technical field of filter presses and comprises a machine frame, a mounting seat is arranged on one side of the machine frame, a feeding pipe is fixedly connected inside the machine frame, a fixing groove is arranged at the top end of the mounting seat, and a screw rod is rotatably connected inside the fixing groove. The device has the beneficial effects that the supporting seat is driven to slide in the fixing groove through the rotation of the screw rod, so that the conveying pipeline can be driven to be separated from the feeding pipe, a worker can conveniently overhaul and maintain the conveying pipeline, and in the separation process of the conveying pipeline and the feeding pipe, the working efficiency is improved. Concrete and liquid of the concrete at the joint of the conveying pipeline and the feeding pipe can fall into the mounting box, the purpose of conveying the concrete is achieved by means of rotation of the filter screen, concrete grout can penetrate through the filter screen and fall into the dust collecting box, and through the structure, the problem that the falling concrete and liquid of the concrete are difficult to clean is solved. Therefore, a relatively clean production environment can be ensured.

The invention belongs to the technical field of metal organic chemical vapor deposition (MOCVD) equipment, and particularly relates to a low-stress MOCVD graphite base and deposition equipment. The graphite base comprises a base body, and at least one stress releasing groove is formed in the outer circle area of the base body. The stress release grooves can be formed in the working face and / or the side face of the outer circle of the base body, additional deformation space is provided for materials, and the stress distribution path is changed, so that stress concentration of the base body in the high-temperature service process is effectively reduced, especially the tensile stress at the outer circle is effectively reduced, and the service life of the base body is prolonged. Therefore, the surface silicon carbide coating is prevented from generating microcracks due to overlarge stress, the corrosion resistance of the graphite base is remarkably improved, and the service life of the graphite base is remarkably prolonged. The stress can be reduced by 35% at most, and the service life of the base is prolonged by 22%. Meanwhile, the invention further relates to metal organic chemical vapor deposition equipment comprising the graphite base.
