  The rules for superfield Lagrangian quantization method for general gauge
theories on a basis of their generalization to special superfield models within
a so-called $\theta$-superfield theory of fields ($\theta$-STF) are formulated.
The $\theta$-superfield generating functionals of Green's functions together
with effective action are constructed. Their properties including new
interpretation and superfield realization of BRST transformations, Ward
identities are studied.
