the processor is used for transmitting the supplementary water quantity to the irrigation decision unit for water supplement analysis to obtain the irrigation water quantity; the irrigation decision unit is used for transmitting irrigation water quantity to the throttling unit, and the throttling unit is used for driving the irrigation module to perform irrigation treatment on the rice field.

The invention utilizes the water-saving analysis subsystem to carry out actual measurement simulation on the rice field, and divides a plurality of longitudinal and transverse staggered irrigation ditches so as to ensure that water flowing out from a corresponding specified position can meet the coverage requirement in the shortest time within the time preset by symbol managers; then, first water quantity information and second water quantity information are obtained through a first testing element and a second testing unit which are arranged;

then measuring to obtain the determined leaf temperature, and determining the supplementary water amount according to the determined leaf temperature, the first water amount information, the second water amount information and the water amount range corresponding to the rice growth period; reversely analyzing the supplementary water amount according to the recent weather, and analyzing by using an irrigation subsystem to obtain the irrigation water amount after updating the supplementary water amount; irrigating the rice with corresponding irrigation water quantity by using an irrigation subsystem; the method not only can consider the substantial growth period of the rice, but also can consider the influence of weather on the rice, thereby avoiding the influence on the rice caused by excessive watering; the invention is simple, effective and easy to use.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
