  We show that the experimental data of mid-rapidity $p_{T}$ spectra for
proton, $\Lambda$, $\Xi$ , $\Omega^{-}$, $\text{K(892)}^{*0}$ and
$\Xi(1530)^{*0}$ in minimum-bias $pp$ collisions at $\sqrt{s}=7$ TeV can be
systemically explained by the quark combination mechanism of hadronization. The
averaged transverse momentum $\langle p_{T}\rangle$ and spectra ratios such as
$\Xi/\Lambda$ and $\Omega/\phi$ calculated from quark combination reproduce the
data much better than those from traditional string and/or cluster
fragmentation. The available data of hadronic $p_{T}$ spectra released by ALICE
collaboration in the first three high-multiplicity classes of $pp$ collisions
at $\sqrt{s}=7$ TeV are also well explained. We make predictions for other
hadrons, and propose two scaling behaviors among decuplet baryons and vector
mesons as the effective probe of hadron production mechanism at such high
collision energy.
