| 摘 要： | 山核桃(Carya cathayensis)是世界著名的干果之一,也是重要的木本油料作物,其油味清香、营养丰富,是优良的休闲保健食品.山核桃长期以来产量不稳、大小年现象明显,通过肥水管理、病虫害防治等有效管理措施,大部分产区大小年现象都明显趋缓,产量逐年上升(黎章矩,2003).我国山核桃研究起步较晚,在其营养方面的研究甚少.

| Abstract: | In order to evaluate the relationship between reflectance spectra parameters and physiological indexes,the reflectance spectra and red edge were characterized in the leaves of two-year-old hickory (Carya cathayensis) seedlings grown under different nitrogen concentration.The results showed that the spectral reflectance gradually became smaller in the visible region with increasing nitrogen concentration,and specifically the reflectance in the range from 525 to 605 nm was changed significantly,which was rega... |
