The optimal result of all factors was educed through the design of three-factor quadric orthogonal and universal rotation regression experiment and optimum design, and some reference and gist were provided for designing maize husker system.

Aim at the questions of maize husker of corn combine harvester and based on the indoor experimentation,conducted through the single factor experiment of the space between the press-pusher\'s axles,the influence orderliness was obtained with the hulling rate,seeds falling rate,the kernel breakage-rate.
