Based on the special need to the cotton transplanting, the planting apparatus of the type of disjoined-soil-boots was design, the earthen bowl seedling damage during transplanting process was reduced, rate of standing seedlings was guaranteed. By way of putting up three dimensional modeling of the planting apparatus of disjoined-soil-boots, virtual prototype has been established. The elasticity coefficient of spring piece, the action point of spring piece and optimum value of the approaching speed of unit have been determined during the experiments of the virtual prototype of planting apparatus, the confirmation through physical prototype was obtained. Thus the design cycle has been reduced, the rated capacity was enhanced.
