  The neutrino masses and mixings are studied in the model which is the
supersymmetric extension of the standard model with local gauged baryon and
lepton numbers(BLMSSM). At tree level the neutrinos can obtain tiny masses
through the See-Saw mechanism in the BLMSSM. The one-loop corrections to the
neutrino masses and mixings are important, and they are studied in this work
with the mass insertion approximation. We study the numerical results and
discuss the allowed parameter space of BLMSSM. It can contribute to study the
neutrino masses and to explore the new physics beyond the standard model(SM).
