Zusammenfassung:	An in-situ detection device for detecting water and fertilizer content in a crop cultivation substrate and a detection method thereof are provided. The in-situ detection device includes a water and fertilizer in-situ collector and a spectrum analysis device. The water and fertilizer in-situ collector that is pre-buried in the cultivation substrate is used to collect water and fertilizer in the cultivation substrate in real time to obtain a measurement sample. The spectral analysis device is used to emit a laser with a specific wavelength to detect and analyze content of nitrogen, phosphorus, and potassium in the measurement sample collected by the water and fertilizer in-situ collector; and a continuous sampling system for continuously transporting the measurement sample is provided between the water and fertilizer in-situ collector and the spectrum analysis device.
