为准确测定叶绿素含量，以大豆品系2146-7为试材，采用随机区组设计方法，研究不同施肥方式对大豆叶片光谱与叶绿素含量的相关性。结果表明：光谱反射率大小为：不施肥处理＞常规施肥处理＞有机肥处理＋常规施肥处理；在可见光710 nm处有一个叶绿素反射吸收谷；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。

In order to determinate the chlorophyll content accurately ,taking soybean strain 2146-7 as material ,u-sing randomized block design method ,correlation analysis about chlorophyll content and spectral characteristics of soybean leaves under different fertilizer treatmens were researched .The results showed that spectral reflec-tance was without fertilizer > conventional fertilizer> organic fertilizer and conventional fertilizer ,there was a chlorophyll absorption valley in 710 nm of visible light ;there was significant correlation on content of chloro-phyll and spectral vegetation indexes such as mSR705 ,mND705 and PSSRc .
