Abstract:
In order to research the effects of nitrogen fertilization on yield and quality of Korla fragrant pear,took the 6-year-old Korla fragrant pear trees as the study objects,set the different nitrogen fertilizer gradient to study the effects on yield and quality of Korla fragrant pear with the different nitrogen fertilizer levels in the field.The results showed that application of nitrogen fertilizer could significantly increase the production of Korla fragrant pear comparing with the non-nitrogen fertilizer treatment,improve the internal and external quality,and the effects of different nitrogen levels were significant differences.According to the comprehensive evaluation,it was the best effect for increasing yield and improving quality to apply nitrogen fertilizer 300 kg?hm-2.Compared with the non-nitrogen fertilizer treatment (N0PK),the yield increased 5 337 kg?hm-2,reducing sugar increased 1.37%,and the total acid reduced 0.1 g?kg-1.In order to ensure the yield and quality of Korla fragrant pear for the best,it suggested that the application rate of nitrogen fertilizer was 300 kg?hm-2.
