Abstract: 【Objective】 To clarify the effects of rhizosphere restricted cultivation mode on leaf photosynthetic and fluorescence characteristics and fruit quality of Korla pear, and provide technical support for the cultivation of Korla pear in arid and salt-alkali area of tarim Basin oasis. 【Methods】 In order to explore the feasibility of 8-year korla pear, leaf photosynthetic characteristics and fruit quality were compared between root zone restricted cultivation mode and traditional root sharing cultivation mode. 【Results】 Under the two cultivation modes, the diurnal variation curve of Pn of Korla pear leaves showed a "double peak" pattern, and there was an obvious photosynthetic nap phenomenon. The daily average value of Pn of Korla pear leaves under the root domain limited cultivation mode was higher than that under the traditional root sharing cultivation mode, while the Gs and Tr were relatively low, and there was no significant difference between different cultivation modes. The Ci daily average was significantly lower than the traditional model, while the Ewu daily average was significantly higher than the traditional model. Fo, Fm, Fv/Fm, Fv/Fm, Φ_PSⅡ and C_NPQ of limited root were all higher than those of traditional cultivation. There were no significant differences in fruit quality, fruit hardness, soluble solids and stone cell content between root limiting plants and control group. 【Conclusion】 The root zone restricted cultivation mode could improve the light capture ability and net photosynthetic rate of korla pear leaves, improve water use efficiency, and significantly reduce the content of fruit stone cells. Comprehensive analysis could be used as a new cultivation mode of Korla pear in the arid and salt-alkali area of tarim Basin oasis.
