The following might be what you are looking for (though I am not sure to 
have understood what you try to achieve),

     Needs["VectorFieldPlots`"]
     vfPlot = VectorFieldPlot[{1, 1}, {x, 0, 1}, {z, 0, 1},
       AspectRatio -> 1, Axes -> True, Ticks -> {None, Automatic}]
     FullForm[vfPlot]
     g = First@vfPlot;
     bunch = Graphics@g
