不同有机肥施用量对梨果实风味品质的影响

Effects of Different Application Rate of Organic Fertilizer on Pear Fruit Flavor Quality

以2个梨品种‘新高’和‘红香酥’为试材,研究不同有机肥用量对其单果重、果实硬度、可溶性固形物含量以及糖、酸组分及含量的影响,并计算果实风味指数。结果表明,合理的有机肥用量有利于提高梨果实产量和果实糖组分含量,降低果实硬度和有机酸含量,提升果实风味;当每666.7m2有机肥用量达2.7 t时,‘新高’和‘红香酥’果实的单果重最大、果实硬度最小,甜度最大、风味最佳。

With two pear cultivars Nakai and Hongxiangsu as experimental materials, the single fruit weight, fruit firmness, soluble solid content and the components and contents of sugars and organic acids as de-termined after different level of organic fertilizer application, and the fruit flavor index was calculated as well. The results indicated that optimal organic fertilizer application rate could enhance the yield and sugar content of pear fruits, decrease the fruit firmness and organic acid content, so the fruit flavor could be improved.When the application rate of organic fertilizer was 2.7 t per 666.7m^2 , the Nakai and Hongxiangsu pear achieved the largest single fruit weight, the lowest fruit firmness, the highest sweetness and the best flavor.
