摘　　要：介绍了一种测量归一化植被差异指数(NDVI,NormalizedDifferenceVegetationIndex)的新仪器。该仪器能快速、方 便、准确地测定农作物在生长的不同时期对氮肥的需求量,确定植物施肥的最佳时机。它具有结构简单、成本低、轻便、低功耗 等特点。该测量仪已被用作测量几种小麦的NDVI值。实验结果表明,该NDVI测量仪测得的数据与ASD公司FR2500地物 光谱仪测定的数据是一致的。A novel device for measuring Normalized Difference Vegetation Index (NDVI) is introduced. The in-season fertilizer nitrogen requirement for the vegetation can be measured correctly, quickly and easily, the best opportunity for application of nitrogen fertilization can be determined. It is portable, simple with less cost and low power assumption. The new device has been used to measure the NDVI of several kinds of wheat. The results are consistent with the ones with the use of ASD FR2500 field spectroscopy.
