In this article, we study the two-body strong decays of the bottom mesons with the heavy meson effective theory in the leading-order approximation and obtain all the analytical expressions of the decay widths of the light pseudoscalar meson transitions among the S-wave, P-wave and D-wave bottom mesons. As an application, we tentatively assign the bottom meson B(5970) as the 2S1(-), 1D1(-) and 1D3(-) states, respectively, and calculate the decay widths of the B-1(5721), B-2(5747), B-s1(5830), B-s2(5840) and B(5970), which may be confronted with the experimental data in the future.
