Based on the movement procedure of the Dibble-type Transplanter, the equation of planting movement for the planting apparatus was established. According to the classic theory characteristic parameter λ>1 planting is necessary for the normal working conditions, computer simulation depending on the equation of planting movement was proceeded. The purpose of the computing simulation is to emulate the movement of the Dibble-type Transplanter. Several kind of values for λ is considered, such as the condition λ<1, λ=1 and λ>1. Through the analysis of the computer results, the classical theory λ>1 is necessary for the normal working conditions is confirmed.
