contents We present a study of the single- and multi-strange particle productions in $p$Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV using the PACIAE 4.0 model. The effects of the color reconnection (CR), rope hadronization (RH) as well as the partonic and hadronic rescatterings (PRS and HRS) on their productions are investigated, respectively. There are two kinds of CR considered: the multiparton interactions-based CR (MPI-CR) and the quantum chromodynamics-based CR (QCD-CR). The four mechanisms studied have little effect on kaon production. However, the QCD-CR scheme incorporating the junction topology gives an enhanced baryon production, but it is still not enough to describe the integrated yields of strange baryons. The combination of QCD-CR and RH scheme together with the flavor ropes (FR) and the string shoving (SS), i.e., QCD-CR+FR+SS, provides a good description of the production of strange baryons. PRS has a weak effect but HRS exerts a promoting effect on the production of multi-strange baryons ($Ξ$ and $Ω$).
