Development of an Intelligent Robot for an Agricultural Production Ecosystem (II) : Modeling of the Competition between Rice Plants and Weeds

摘要

Models of competition based on the Lotka-Volterra equation are introduced in this researching in order to develop an intelligent robot for a rice production ecosystem. These prediction equations are useful to estimate the competition between populations or biomasses of rice plants and weeds in different phases of the rice crop season and using this information about the superior plants, the robot will make decision about the appropriate timing for removing the snails in excess in paddy field; therefore snails remaining in the field can eat weed and rice plants will grow up with less competition.
