Claim 5:
6. The decision-making method according to claim 5, wherein
in step S53, a method for constructing the optimized airborne canopy temperature sensor network comprises:
according to distances between the airborne canopy temperature sensors and the center pivot of the irrigation sprinkler, based on a principle that measurement data obtained from each of the airborne canopy temperature sensors represents an equal observation area, optimizing positions of the airborne canopy temperature sensors placed along the truss direction of the irrigation sprinkler; and
calculating a distance Rm between an mth airborne canopy temperature sensor of the airborne canopy temperature sensors and the center pivot of the irrigation sprinkler according to the following formula:

Rm=R×√{square root over (m)}/√{square root over (X)};

wherein, R represents a radius of a circular area irrigated by the center pivot irrigation sprinkler, and X represents a number of the airborne canopy temperature sensors.
