The utility model relates to a soil sampling and moisture measurement device for drip-irrigation trials, which comprises a positioning device, a sampling scale, a pushing device and a sampling drill pipe, wherein the pushing device consists of a threaded fulcrum bar, wherein the bottom end of the threaded fulcrum bar and a connecting bar are arranged together through pushing device fixed holes, a rocking handle is arranged at the top of the threaded fulcrum bar, and a spring is arranged on the threaded fulcrum bar and positioned below a moving scale; the sampling drill pipe is a hollow circular pipe with an edge seam, a hollow circular pipe threaded opening is formed in the top of the hollow circular pipe, and a wedge-shaped head is arranged on the tail end of the hollow circular pipe; and a circle center of an outer ring, a circle center of an inner ring, the center of the pushing device fixed hole and the center of a pushing device installing hole are in the same line. The device overcomes the defects that the existing single soil auger is time-wasting and labor-wasting to sample, has an impact on the trail results and the like, the trial cost can be lowered, the trial precision and the working efficiency can be improved to a greater extent.
