The invention discloses a multi-row electrostatic spinning spray head, which belongs to the field of electrostatic spinning. The spray head comprises a connecting piece, a flow guide core and an independent temperature control device, wherein the connecting piece is connected with the flow guide core in a matching way and provided with a trapezoidal open flow channel and a bump for guiding a material; the bump is provided with a spinning tip for jet flow molding; the flow guide core is provided with a balancing groove for balancing the material in each open flow channel, a flow guide bump anda spinning tip for forming spinning; and when the spinning tip is provided with solution or melt and an electrostatic field is formed, a plurality of rows of jet flow is formed at the spinning tip. The conventional electrostatic spinning changes from a single yarn discharging way to a multi-yarn and multi-row parallel strip form and a spliced open flow channel is adopted, so that the flow guide core can be extracted directly when an experiment ends, the open flow channel is opened truly and the problems of easy blocking and difficult cleaning of a capillary tube are solved.
