The present invention discloses a portable soil greenhouse gas sampler. Comprising a gas cylinder, A piston is connected in the gas cylinder in a sliding way, The piston is fixedly connected with the pull rod, the pull rod is connected with the air collecting cylinder in a sliding mode, the air collecting cylinder is fixedly connected with the air suction pipe, the three-way valve is arranged on the air suction pipe, the connecting pipe is arranged on the three-way valve, the mounting pipe is sleeved on the outer side of the connecting pipe in a sliding mode, the air collecting bag is arranged on the mounting pipe, and the dismounting mechanism is arranged on the mounting pipe and the connecting pipe together. Through the arrangement of the structures of the pull rod, the piston, etc., the utility model has the advantages of simple structure and convenient operation. Operators can conveniently carry out manual repeated drawing operation. The gas in the static box can be fully mixed, and the slender pull rod design can easily push the gas sample into the sample bottle with a pressure of 2-3 atmospheres in a labor-saving manner, and under the action of the three-way valve, piston, connecting pipe and other structures, The gas mixed inside the collection tube of the static box can be collected into the gas collection bag, which is convenient for the operator to collect and use.
