PURPOSE:To finely adjust the rate of spraying of particulate matter from apertures so that said matter is economically and efficiently sprayed with a sprayer for the particulate matter of a fertilizer, agricultural chemicals, etc., by forming the titled nozzle in such a manner that the size of the apertures provided on the side wall of the nozzle can be adequately adjusted. CONSTITUTION:The root end part of a pipe 7 is connected via or without via a flexible hole 6 to a container 5 for the particulate matter and the nozzle 10 for discharging the particulate matter is provided on the front end part of said pipe 7. A 1st member 11 which communicates integrally with the pipe 7 and has the side wall 15 to a plate body 12 and the 2nd member 18 which has the side wall 20 on a plate body 19 and of which the side wall 20 is slidably fitted in the longitudinal direction of both said side walls are provided on the nozzle 10. The apertures 16, 22 and non-apertures 15a, 20a which open and close said apertures of the members facing each other are alternately provided in plural pieces at prescribed spaced intervals in the longitudinal direction on the two side walls 15, 20. As a result, the spraying rate of the particulate matter from the apertures is finely adjusted and the particulate mater is economically and efficiently discharged and sprayed.
