| 摘要: |
| 通过在两个县麦田和校试验地共29个样点的光谱反射率测定,结合小麦生育状况和籽粒产量分析,可以看到小麦具有和其它绿色植物一样的光谱反射率特征,但也有自己本身值域。而在小麦不同发育期内又有它一定的变化规律,其中以抽穗期反射率为最高。从对不同波段反应上看第一波段(兰光)和第四波段(红外)与产量相关最为密切,经过对不同波段资料处理和运用积分回归技术我们得到了小麦光谱特性与估产模式。 |

| Abstract: |
| Through the measurement and analysis of the growing Condition and ear of grain in 29 Sample Sites located in the field of two Counties and the experimntal plots of our University,We have come to the conclusion that wheat possesses most distinguishing feaure of reflective spectrum like those of other green plant.But it has its own special feature,The Curves of wheat reflectivety usually change with its different growing stae and has certain rule of change.It reaches the highest value during the ear stage.The... |
