  The maximal graded subalgebras for four families of Lie superalgebras of
Cartan type over a field of prime characteristic are studied. All maximal
reducible graded subalgebras are described completely and their isomorphism
classes, dimension formulas are found. The classification of maximal
irreducible graded subalgebras is reduced to the classification of the maximal
irreducible subalgebras for the classical Lie superalgebras $\frak{gl}(m,n)$,
$\frak{sl}(m,n)$ and $\frak{osp}(m,n)$.
