Evaluation of growth and nutritive values of forage crop using hyperspectral sensor in the field level

开发了一套田间水平的牧草收获期光谱信息获取系统。利用安装在拖拉机上的高光谱传感器，利用该系统估算了牧草作物的化学成分。推测化学成分的估算模型具有足够的精度，并生成了营养价值的田间地图。此外，还从植物的光合作用能力来评价杂草淤积地的植物竞争效应。

A system was developed to acquire spectral information of forage crop during harvest at the field level. Chemical compositions of forage crop were estimated using the system with a hyperspectral sensor mounted on a tractor. It was speculated that the estimation models for the chemical compositions had sufficient accuracy, and field maps of nutritive values were generated. In addition, the effect of plant competition at the field which was chokedup with weeds was evaluated by photosynthetic ability.
