PROBLEM TO BE SOLVED: To provide a gas and liquid injector which simultaneously injects air, a chemical solution, etc. into soil, improves fertilizing, controlling and disinfecting effects, etc. by its synergistic effects, can ejects air, the chemical solution, etc., individually, is compact and readily handleable. SOLUTION: An air route 2 and a solution route 3 are made to communicate with the top of an injecting pipe 1 having an injecting hole 4 equipped with an air jetting hole 4a and a jetting hole 4b for a chemical solution, etc. at the bottom and provided with the air route 2 and the solution route 3 in the inside. An air route 2a and a solution route 3a having on-off valves 6 and 7 in the inside, respectively are installed at a fixed interval. The air route 2a and the solution route 3a are individually extended to the interiors of operation handles 8 and 9 arranged at both sides of the routes. One operation handle 8 is used as a connection part 8a for an air charging apparatus and the other handle 9 is used as a connecting part 9a for a solution charging apparatus. Opening and closing levers 24 of the on-off valves 6 and 7 are graspably placed at the lower part of the operation handles 8 and 9.
