摘要：AbstractThe nutrient estimation is an important basis for water and fertilizer management in the field. In order to achieve crop nutrient content for variable-rate fertilization, a spectrum device based on the Ocean Optics STS-VIS sensor was developed to measure the spectral reflectance at 350-800 nm. The spectral reflectance data could be measured by optical sensor, data transmission module and the controller. The control software was developed with functions such as acquisition parameters, acquisition control and data management. Before the field application, the calibration experiments were conducted. The correlation was analyzed between the developed device and ASD Field Spec Hand Held 2. The result showed that the average correlation coefficient value was 0.94. It was used to detect the chlorophyll and moisture content of potato plant. The SPAD regression model was established and the determinant coefficient R2was 0.484, moisture content regression model was established and R2was 0.735. Results showed that the device has a certain ability to predict chlorophyll content and moisture content of potato leaf.
