Abstract
A rice nitrogen of panicle fertilizer accurate recommendation method based on crop model and remote sensing coupling includes the following steps: S. constructing a basic database; S. agricultural parameter inversion modeling based on the remote sensing vegetation index; S. rice nitrogen nutrition diagnosis based on the nitrogen nutrition index NNI; and S. accurately recommending panicle fertilizer nitrogen based on a crop growth model and remote sensing nitrogen nutrition diagnosis. According to the method, the rice growth trend and nitrogen nutrition estimation in the key growth period is achieved through a remote sensing inversion technology, a multi-source remote sensing inversion spatial dataset based on the rice growth trend is taken as a combination point coupling crop growth model to simulate the rice yield in real time, the rice nitrogen nutrition condition and the nitrogen demand are further combined, and the plots-level nitrogen of panicle fertilizer accurate recommendation is finally achieved.
