The invention discloses a water and
fertilizer integrated precision management and
control system and a control method. The water and
fertilizer integrated precision management and
control system comprises a head device and a field
tail device, wherein the head device comprises an
irrigation system, a fertilization
system and a head
control system, and the
irrigation system comprises an irrigationpump, an
irrigation pipeline, a
pressure sensor, an irrigation flow meter, a
filtration system and an irrigation valve; the fertilization system comprises a fertilization pump, a fertilization pipeline, a fertilization flow meter and a fertilization valve, and the field
tail device comprises a
tail irrigation system and a field control system; the tail irrigation system comprises a field pipeline, a
solenoid valve and a
drip irrigation pipe, and the field control system comprises a field control box, a field
power module, an EC sensor and a
moisture sensor. According to the water and
fertilizer integrated precision management and control system disclosed by the invention, the
moisture sensor and the EC sensor are arranged according to the optimal water and fertilizer absorption position at the root of the
crop, and the applying amount and reaching position of water and fertilizer in the actual irrigation and fertilization are detected, so that the water and fertilizer waste are effectively avoided, and thus the water and fertilizer content in the root of the
crop is not too high or too low, which promotes
crop growth.
