The invention disclosed a compound fertilizer which comprises basic nutrition fertilizer including nitrogen, phosphorus and potassium, and also comprises gamma-polyglutamic acid and seaweed extract, wherein the gamma-polyglutamic acid accounts for 0.1-2% of the basic nutrition fertilizer, and the seaweed extract accounts for 0.5-2% of the basic nutrition fertilizer. The compound fertilizer containing the gamma-polyglutamic acid and the seaweed extract has high activity biological function, and is capable of improving the yield and the resistance capability such as disease resistance, drought resistance, cold resistance, lodging resistance and the like of crops. Therefore, the compound fertilizer can be widely applied to grain crops such as wheat, rice, corn and the like, and cash crops such as tomatoes, melons, grapes and the like. One-off fertilization can be realized without topdressing, and the yield of the crops can be increased by 10-30%.

The invention relates to a polyurethane foam combined explosion-proof device and a polyurethane foam material, belonging to the technical field of explosion-proof structures. The device includes a cylinder and a cover, the cylinder is made of polyurethane foam, the cover includes a polyurethane foam cover and a liquid cover, the polyurethane foam cover is located at the upper end of the cylinder and embedded in the cylinder, and the polyurethane foam cover is embedded The depth inside the barrel is adjustable, the liquid cover is located above the barrel and covers the polyurethane foam cover, and an air gap is left between the liquid cover and the polyurethane foam cover.
