1 Overview Nursery nursery shed in greenhouse, some countries use the rolling structure, Beijing Longshan nursery imported from the United States a rolling nursery shelves, Lanzhou sand research imitation American nursery stand, although its rolling orbit has been improved, but the basic structure Is still the American-type nursery shelves, shed seedling tray transport is still a problem. YMJ-1 type mobile nursery stand has been researched domestically.

However, when it is handled by hand, it is labor-intensive, time-consuming and labor- . In order to solve the transport of seedlings in the shed issue, we are in the "forest container seedling factory production technology and mechanical design
