Abstract
The invention discloses a rhizosphere sampler for sampling rhizosphere soil and a sampling method of the rhizosphere sampler. The rhizosphere sampler comprises a gas absorbing device and a bracket, wherein the gas absorbing device is arranged at the bottom of the bracket, movable rods and movable bands are arranged on the bracket, and hooks are arranged on the movable rods. The bracket is a telescopic mechanism, and comprises a plurality of telescopic pipes which are mutually sleeved together. The gas absorbing device absorbs the bottom of a planting disk, and is capable of fixing the bracket; and a plant is tied by regulating the positions of the bands on the bracket, so as to be fixed; and then the hooks can be enabled to bear a round pipe in a proper position through regulating the two movable rods on the bracket and round rods thereon. In addition, the telescopic pies used by the rhizosphere sampler can be opened or closed; and the plant root can be firstly placed in soil through the telescopic pipes, and then the telescopic pipes are closed. Therefore, the rhizosphere sampler is convenient to operate, and is capable of quantitatively and accurately obtaining rhizosphere soil. In addition, because a certain amount of micropores are formed in the walls of the telescopic pipes, the situation that normal growth of the plant root in the telescopic pipes is influenced due to oxygen deficiency can be avoided.
