英文简介The maize usually has an obvious vertical distribution characteristic of canopy nitrogen. When it under a nitrogen stress, the lower canopy leaves often firstly show the corresponding nutritional deficiency symptom. Therefore, an early diagnostic methods of the middle and lower maize canopy nitrogen status is urgently needed. The goal of this project is how to build a nitrogen version model basing on canopy nitrogen vertical distribution characteristics by hyperspectral remote sensing, and finally to realize the rapid and accurate monitoring nitrogen nutrition status of maize. There are three research contents, including: (1) to clarify the relations between the nitrogen vertical distribution characteristics and the light distribution characteristics in maize canopy, and build mathematical model of maize canopy nitrogen vertical distribution. (2) to study spectral response characteristics of maize canopy nitrogen vertical distribution and their relationships with the light distribution characteristics, and to determine the spectral contributions of different vertical layers to the entire canopies and canopy detectable depth. (3) to build the nitrogen version model basing on canopy nitrogen vertical distribution characteristics by hyperspectral remote sensing and test its effectiveness. The study results can offer the theoretical and technological basis for crop precise and variable rate nitrogen management.
