Abstract

Abstract: In order to increase the utilization rate of fertilizer and promote the growth of crops,this paper studied the effect of fertilizer additives on spectrum characteristics and the chlorophyll fluorescence parameters in sweet potato. The research was designed four treatments:conventional fertilization(CK),based on conventional fertilization, poly amino acid additive(T1), poly amino acid additive+inhibitor(T2),poly amino acid additive+inhibitor +bacterial manure(T3).The results showed that:the average reflectance of canopy spectra at 550 nm band was the order:CK > T2 > T1 > T3,and the average reflectance at near infrared wavelengths (760-950 nm) was the order:T2 > T1 > CK > T3.Compared with the conventional fertilization, Photochemical Reflectance Index (PRI), Structure Insensitive Pigment Index (SIPI) and Simple Ratio Vegetation Index(SRVI) under fertilizer additives increased, Red Edge Normalized Difference Vegetation Index (NDVI₇₀₅) and Difference Vegetation Index(DVI) under fertilizer additives decreased respectively. Under fertilizer additives,the chlorophyll fluorescence parameters Fo, Fo/Fm, DIo/RC decreased,the chlorophyll fluorescence parameters Fv/Fm, Fv/Fo, TRo/RC, ETo/RC,from φEo,φPo,Ψo and PI abs increased.Compared with the conventional,the Fv/Fm, Fv/Fo and PI abs under the treatment of T1 were the highest,which increased by 1.20%,5.75% and 13.71% respectively; Under fertilizer additives,photosynthetic parameters of Ci,Pn,Tr,Gs increased.Compared with the conventional,the Ci and Tr under the treatment of T1 were the highest,which increased by 63.08% and 37.27%. Compared with the conventional,the Pn and Gs under the treatment of T2 were the highest,which increased by 39.27% and 202.36%,respectively.
