The invention belongs to the technical field of plant protection nozzles and discloses an impinging stream theory based plant protection sector atomizing method and a sector atomizing device. The plant protection sector atomizing method and the sector atomizing device are characterized in that two sector jet flows are realized in a nozzle or atomizing device and flow, nearby a terminal liquid outlet of the nozzle, towards each other at a high speed by a certain included angle to realize collision, and the two sector jet flows are broken in collision on a collision face into dispersed blocks indifferent shapes to further form sector mist uniform in droplet size. The sector atomizing has advantages of narrow droplet spectrum and high particle size uniformity, droplets in the middle of the an atomizing sector plane are large and uniform in particle size while droplets on two sides of the atomizing sector plane are small in size, and accordingly the small droplets in an overlapped area ofedges of two adjacent ato
