The invention provides an intelligent
sowing and fertilization
control system for rice and a control method of the intelligent
sowing and fertilization
control system in the technical field of agricultural control. The
control system comprises a central
processing module, a rotary
tillage control module, a
sowing control module, a fertilization control module, a suppression control module and a
pesticide spray control module, wherein speed sensors are mounted on hubs of wheels of a
tractor; the sowing control module comprises multiple single seed box control units in one-to-one correspondenceto seed metering devices, the single seed box control units send detected seed box
mass to the central
processing module, and the central
processing module calculates the seed metering quantity and controls the rotating speed of a seed metering motor according to the calculated seed meeting quantity; and the fertilization control module comprises multiple single
fertilizer discharge control unitsin one-to-one correspondence to
fertilizer dischargers, the single
fertilizer discharge control units sends the detected fertilizer box
mass and the rotating speed of a fertilizer
discharge shaft to the central processing module, and the central processing module calculates the fertilizer discharge quantity and controls the rotating speed of a fertilizer discharge motor according to the calculatedfertilizer discharge quantity. The control
system guarantees the uniformity of rotary
tillage, sowing, fertilization and
pesticide spraying.
