| 摘 要： | 为了探究氮肥对库尔勒香梨产量和品质的影响效应,在田间条件下,以6年树龄的库尔勒香梨树为研究对象,研究了不同施氮水平对库尔勒香梨产量和品质的影响。结果表明:与不施氮肥的处理相比,施用氮肥能明显提高库尔勒香梨的产量,改善香梨的内外部品质,不同施氮水平对库尔勒香梨产量和品质的影响效果差异较为显著。综合评价库尔勒香梨园施氮量为300kg·hm~(-2)时,与不施氮肥的处理(N0PK)相比增产5 337kg·hm~(-2),还原糖提高1.37%,总酸降低0.1g·kg~(-1),在增产、增效和改善果品方面效果最佳。为保证库尔勒香梨产量和品质均达最优化,建议库尔勒香梨园施氮量为300kg·hm~(-2)。

| 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 300kg·hm-2.Compared with the non-nitrogen fertilizer treatment(N0PK),the yield increased 5 337kg·hm-2,reducing sugar increased 1.37％,and the total acid reduced 0.1g·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 300kg·hm-2. |
