      In this paper we mainly study the negative $\mathbb{Z}$-homogeneous derivations from the even part of the finite-dimensional odd Hamiltonian superalgebra $HO$ into the odd part of generalized Witt superalgebra $W$ over a field of prime characteristic $p>3.$ Using the generating set of $\mathcal{HO},$ by means of calculating actions of derivations on the generating set, we first compute the derivations of $\mathbb{Z}$-degree ${-1},$ then determine the derivations of $\mathbb{Z}$-degree less than ${-1}.$
