The utility model discloses an apparatus for testing wind-drift sand through a drawer-type unit cylinder and influence on a plant caused by wind-drift sand. The apparatus is characterized in that a diameter-changing cylinder and a rectangular cylinder are integrated in a second unit cylinder, one end of the diameter-changing cylinder is connected with a first unit cylinder, and one end of the rectangular cylinder is connected with a third unit cylinder; the bottom of the rectangular cylinder is provided with a drawer type sand providing device, the drawer type sand providing device comprises a first drawer and a second drawer, the widths of the first drawer and the second drawer are the same as the width of the rectangular cylinder of the second unit cylinder, small eaves are disposed at two sides of the first drawer and the second drawer, and between the first drawer and the second drawer, and two sides of the first drawer and the second drawer are provided with handles. The rear side of a third unit cylinder is provided with an opening facing to a sand collector, the side of the third unit cylinder is provided with a glass sliding door, and a round groove in the bottom is provided with a flowerpot. When sand in the drawer type sand providing device is blew, a condition of wind-drift sand in natural conditions can be simulated in the unit cylinders, changes of plant physiology and plant ecology can be tested, experiment data about influence on land plants on the soil surface caused by wind-drift sand in artificial natural wind and sand environments can be provided.
