The invention relates to a martensite broad hot strip with tensile strength of 1500MPa level and a production method of the martensite broad hot strip. The martensite broad hot strip comprises C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulphur), Nb (niobium), Ti (titanium) , B (boron), AlS (acetolactate synthase) and N (nitrogen), with the balance being Fe and inevitable impurity elements. Weight percentages of the C, the Si, the Mn, the Nb, the Ti, the B and the AlS are 0.13-0.17%, 0.40-0.60%, 1.30-1.60%, 0.020-0.050%, 0.02-0.05%, 0.0010-0.0030% and 0.010-0.060% respectively. Weight percentages of the P, the S and the N are smaller than or equal to 0.025%, 0.020% and 0.005% respectively. The production method includes smelting molten steel according to the set components, and subjecting the molten steel to continuous casting to obtain a plate blank; heating the plate blank to 1240-1300 DEG C, and performing high-pressure water descaling, controlled rolling, control-rolled cooling and reeling to obtain the broad hot strip. The produced broad hot strip has the advantages that yield strength is larger than 1000MPa, tensile strength is larger than 1500MPa, and ductility is larger than 10%; the broad hot strip is applied to hot-rolled plates of shear blades of excavators, a quenching process is omitted, and production cost is saved.
