Design and Test of Variable-rate Fertilization Control Device of Precision Planter for Soybean
Utilizing the favorable condition of Heilongjiang reclamation area carrying out the precision agriculture sample, we have developed an automatic control device with the variable rate fertilization. This device adopts industrial control computer is upper machine and variable rate fertilization controller for single chip computer as the core is lower machine, it is to be used to the accompaniment of 6-line soybean precision planter, and it uses an electric control CVT(Continuously Variable Transmission) which controls the transmission ratio of discharging fertilizer system of the planter to change the volume of applying fertilizer. We carried out planting tests of the variable-rate fertilization with this control device on the 852 farm in Heilongjiang province in 2005 and achieved good results.
