Abstract：Pepper leaves with iron deficiency， manganese deficiency and iron-manganese double deficiency were obtained by hydroponics in the intelligent greenhouse， respectively. The chlorophyll fluorescence parameters and reflectance spectra of pepper leaves with different levels of deficiency were measured， respectively. The support vector machine was used to establish a rapid diagnosis model for the deficiency types of yellow leaves. The results showed that chlorophyll fluorescence technology and hyperspectral technology were feasible to diagnose iron and manganese deficiency in greenhouse pepper.

Key words：iron;manganese;nutrient deficiency stress;pepper;chlorophyll fluorescence parameters
