Abstract: 【Objective】 To study the effects of different irrigation methods on the fruit quality Korla fragrant pear with a view to providing theoretical basis for improving the effective utilization rate of water resources in pear orchard and improving the fruit quality. 【Methods】 With 16 years of Korla fragrant pear as the test material, using three irrigation methods: trench irrigation, drip irrigation and irrigation, the effects of different irrigation methods on the fruit quality was compared, and suitable irrigation methods were screened. 【Results】 Compared with the control of large water irrigation, drip irrigation significantly increased the fruit desorization rate, the color was ruddy, the fruit single fruit weight, fruit index, the thickness of the cuticlelayer layer increased significantly, and the hardness and VC content of the fruit decreased significantly. The fruit weight of ditch irrigation was reduced, while fruit-shaped index, fruit hardness, Vc content, wax layer and wood hydrant layer thickness increased, and the overall quality of fruit of drip irrigation was obtained by the main component analysis, followed by ditch irrigation; The 3-2 treatment of diffuse irrigation is conducive to the growth of the fruit, the fruit quality was better than the fruit quality of the ditch irrigation treatment, 3-2 treatment was more conducive to improving the comprehensive quality. 【Conclusion】 Compared with the current traditional irrigation, appropriate reduction in irrigation can save water greatly and improve the fruit quality of 'Korla pears'.
