PROBLEM TO BE SOLVED: To make a spraying pipe for spraying light without increasing the cost and enlarging the size, improve weathering resistance and corrosion resistance and handling property for disassembly and assembly, heighten the strength to make the pipe hardly bent and broken owing to contact with soil and products, and increase the workability. SOLUTION: This granular matter spraying apparatus is provided with a base spraying pipe 50 made possible to swing up and down and be fixed in the fallen state and in the stood up state and a prescribed number of spraying pipes 60 for spraying for extension by being successively joined to the base spraying pipe 50. The spraying pipes 60 for spraying are tapered pipes made of a reinforced plastic and tapered gradually narrowed to the tip sides and the outer circumferential sides of the tip end parts 60a of the spraying pipes 60 for spraying in the base spraying pipe 50 side are made to be joined by taper-fitting to the rear end parts 60b of the next adjacent spraying pipes 60 for spraying.
