| 摘 要： | 用Unispec光谱分析仪和SPAD叶绿素仪测定了2个品种从初花期到成熟期的反射光谱和叶绿素含量.用SPAD叶绿素仪测定结果表明:每个时期均为合交98-1667的叶绿素含量高于合丰55号;用Unispec光谱分析仪测定结果显示:合丰55号大豆的光谱反射率高于合交98-1667,并且发现在可见光510 nm～610 nm处有一个叶绿素反射吸收峰,此吸收峰是大豆叶片上特有的一个特征值.数据统计分析表明:叶片叶绿素含量与光谱植被指数mSR705、mND705,和PSSRc具有极显著相关性.说明可以通过测量叶片光谱的方法来监测大豆叶片叶绿素含量.

| Abstract: | Spectral reflection and chlorophyll content are measured respectively by Unispec spectrometer and SPAD chlorophyll meter from initial flowering to maturing of two soybean cultivars.The chlorophyll content of Hejiao 98-1667 was higher than that of Hefeng 55 in each measured period.The spectral reflectance of Hefeng 55 was higher than that of Hejiao 98-1667.A chlorophyll reflection absorption peak was observed in 510-610 nm wavelength,which maybe a unique eigenvalue of soybean leaves.Statistical analysis show... |
