The invention discloses a large-thickness steel plate for a low-temperature pressure container and simultaneously relates to a production method of the steel plate. The large-thickness steel plate for the low-temperature pressure container, disclosed by the invention, comprises the following chemical components in percentage by weight: 0.07-0.12% of C, 0.20-0.40% of Si, 1.40-1.60% of Mn, 0.60-0.80% of Ni, not more than 0.010% of P, not more than 0.003% of S, 0.020-0.045% of Al, 0.02-0.05% of Nb and the balance of Fe and inevitable impurities. The production method of the large-thickness steel plate comprises the following steps: smelting, casting, heating, rolling, performing heat treatment and getting a finished product. The large-thickness steel plate produced by the method disclosed by the invention has the characteristics of high purity, higher ballistic work at the temperature of minus 70 DEG C and Z-direction section shrinkage rate and good welding performance, and can be widely applied to petrochemical, coal chemical and other engineering products, and the application prospects are broad.
