The strong decays of experimentally observed excited nonstrange charmed mesons are analyzed in the framework of heavy quark effective theory (HQET). The ratio of the strong decay rates identified the doublets as , as and as . The is interpreted as the mixing of states. The resonances and are identified with and quantum states, respectively. Such states allows to construct the Regge trajectories in and planes. We fix the slope and the intercept of each Regge line and estimate the masses of higher excited nonstrange charmed mesons which are lying on the Regge lines. Also, the ratios of the strong decay rates of this higher excited nonstrange charmed mesons are calculated. It can provide valuable information to future experimental search.
