We realize an experimental facility for cooling and trapping strontium (Sr) atoms and measure the Lande g factor of $^{3}$D$_{1}$ of $^{88}$Sr. Thanks to a novel repumping scheme with the $^{3}$P$_{2}$$rightarrow$$^{3}$S$_{1}$ and $^{3}$P$_{0}$$rightarrow$$^{3}$D$_{1}$ combination and the permanent magnets based self-assembled Zeeman slower, the peak atom number in the continuously repumped blue MOT is enhanced by a factor of 15 with respect to the non-repumping case, and reaches $sim$1 billion. Furthermore, using the resolved-sideband Zeeman spectroscopy, the Lande g factor of $^{3}$D$_{1}$ is measured to be 0.4995(88) showing a good agreement with the theoretical value of 0.4988. The results will have an impact on various applications including atom laser, dipolar interactions, quantum information and precision measurements.
