An apparatus for monitoring comprehensive growth condition of potted lettuce consists of a polarized hyperspectral imaging system and a 3D laser scanning system. The polarized hyperspectral imaging system includes a control system, a dual-coordinate sample holder, an image acquisition system, and a light source system, and the polarized hyperspectral imaging system detects water and fertilizer stress in lettuce by polarized hyperspectral multi-dimensional reflection imaging of characteristics on a canopy/leaf scale. The 3D laser scanning system detects morphological characteristics such as the biomass, stem diameter, plant height, and leaf area of lettuce. The method includes: step 1: culturing samples: cultivating the potted lettuce under a water stress, and under a nitrogen stress and water stress; step 2: acquiring morphological data of an entire lettuce plant; step 3: processing and analyzing data; step 4: correcting a model by using a water compensation factor; step 5: establishing a multi-characteristic integration model.
