Water and fertilizer integrated precision management and control system and control method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of micro-water irrigation, in particular to a water and fertilizer integrated precision control system and control method. Background technique [0002] In recent years, because micro-irrigation has many advantages such as water saving, high irrigation uniformity, labor saving, fertilizer saving, and production increase, it has developed rapidly and has been widely used. It has become an important technical means in agricultural production. At present, the national micro-irrigation application area It has reached more than 50 million mu. Micro-irrigation is to transport water and nutrients to the roots of crops with a small flow rate through the pipeline system and special sprinklers (drip heads, micro-sprinklers, seepage irrigation pipes and micro-pipes, etc.) installed at the tail (on the final pipeline), Irrigation method to keep the soil in the best state of water, fertilizer and air. Because micro-irr...
