| 摘 要： | 水稻移栽于添加不同量镉(50、100、200和400 ppm)的土壤上,叶片反射光谱特性发生变化:可见光区反射率增加,其中550—680nm波段反射率的增加更突出;反射光谱的一次微分图和二次微分图上叶绿素吸收边缘明显蓝移。这些变化以分蘖期最为显著。镉害水稻可见光区反射特性的变化与叶片中叶绿素含量的降低相一致。初步确定几个波段可用于区分镉毒害的和正常的水稻的光谱反射特性。

| Abstract: | Rice seedings were planted on the soil treated with different amount of cadmium as CdCl2.There were five cadmium treatments in this study,i.e.O (control), 50, 100, 200 and 400 ppm of Cd. The growth and development of the treated plants were inhibited and their spectral reflection properties were changed .In the visible region of spectrum,the reflectance increased,among which in the 500-680 nm waveband,the increase of reflectance was remarkable.The first-and second-spectra showed a chlorophyll absorption edg... |
