A new type of 2B-JP-FL01 seed-metering device was studied through technology of cyber-vision, in order to optimize its configuration. The basic structural parameters were used as primary testing factors, multi-parameter and multi-level experimentation were the experimental method. Professional software was used to gain recursive model among testing factors and capability, such as eligible exponential, omitting seeding exponential and variance coefficient of plant spacing, at the same time, the influencing theory was synthetically analyzed. All of these provide the theoretical references for selecting seed-metering device with fitting dimension for a series of seeding-machine.
