Abstract

A multispectrum image diagnosis system of rape nitrogen nutrition is prepared as connecting one end of 3CCD multispectrum shooting unit to rape canopy multispectrum image information and calibration board multispectrum image information and setting another end with two interfaces as one being connected to computer serial interface through RS ¿C 232 interface and another one being connected to image receiving board through digital image collecting line, connecting output end of image receiving board to computer. The method for diagnosing rape nitrogen nutrition with multispectrum image is also disclosed.

Description

technical field [0001] The invention relates to a multi-spectral image diagnosis method and a diagnosis system of rapeseed nitrogen nutrition. Background technique [0002] Nitrogen nutrition diagnosis is the core of plant nutrition diagnosis. Nitrogen fertilizer is the most widely used chemical fertilizer in the world, and it is also the most difficult to quantify accurately in the recommended fertilization. Tracing it to its cause is mainly due to the lack of testing methods that can accurately, rapidly and economically judge the nitrogen nutrition status of crops and determine the nitrogen fertilizer requirement. For a long time, the nitrogen nutrition diagnosis of crops and the recommended fertilization of nitrogen fertilizers have been based on routine laboratory tests. However, traditional testing methods require a lot of manpower and material resources in terms of sampling, measurement, and data analysis. For destructive detection, it is not conducive to popularizat...
