The embodiment of the specification provides a precise fertilization method based on real-time detection of soil fertility, an image acquisition module, a light wave generation and recovery module and a fertilization control assembly are configured in a fertilizer applicator, images are acquired to identify characteristic leaves, light waves are emitted to the leaves according to the sequence of proportions in absorption spectrums of different pigments from high to low, and the fertilization control assembly is used for controlling fertilization. The light wave recovery module generates a reflection sequence according to a receiving sequence, and the data processing module compares the reflection sequence generated in real time with a pre-configured reference reflection sequence and calculates the current content of each pigment of the leaf; the fertilization formula, the fertilization amount and the next fertilization time are planned according to the current pigment content, the target content and the curre
