The present disclosure relates to the field of intelligent warehousing technologies, and provides a shelf and a warehousing system, to resolve a technical problem that it is difficult to control a spacing between adjacent goods on a shelf. The shelf includes a support frame and a first conveyor and a second conveyor arranged on the support frame. The first conveyor and the second conveyor form a goods conveying layer for conveying goods. The first conveyor is hinged with the support frame. The first conveyor is rotatably switched to a first limit position or a second limit position. When the first conveyor is at the first limit position, a second end of the first conveyor protrudes from an upper surface of the second conveyor, so that an end surface of the second end of the first conveyor is configured to block goods on the second conveyor. The warehousing system includes the above shelf. The present disclosure is intended to precisely control the spacing between adjacent goods on a shelf.
