Provided are a steel material and a method for producing the same. The steel material exhibits excellent hydrogen embrittlement resistance in a high-pressure hydrogen gas environment and is, therefore, suitable for use in hydrogen storage tanks, hydrogen line pipes, and the like. A steel material for a high-pressure hydrogen gas environment has a predetermined chemical composition. The steel material has a tensile strength of 560 MPa or higher, and a fracture toughness value KIH exhibited by the steel material in a high-pressure hydrogen gas atmosphere is 40 MPa ·m1 / 2 or higher.

This invention discloses a closed-loop soil improvement method for vineyards using organic fertilizer synergy, comprising the following steps: seasonal directional grass cultivation, preparation of Bacillus subtilis agent, preparation and application of self-made organic fertilizer in the early stage of vineyard establishment, and closed-loop synergistic improvement method; the closed-loop synergistic improvement method is divided into early stage improvement and late stage improvement, relying on grass return to the field and Bacillus subtilis to maintain soil fertility and nutrient cycle.
