于大田条件下，试验比较了2个增香施肥处理T1（传统施肥模式+馫香1号肥）、T2（香稻增香专用肥）和CK（传统施肥模式）对香稻品种青香优19香产量、品质及香气风味挥发物的影响。结果表明，与CK相比，T1和T2处理的香稻产量分别显著提高9.94%和11.94%，糙米率、精米率和整精米率亦均有提高，籽粒中2-AP（2-乙酰基-1-吡咯啉）含量分别提高11.11%和33.83%。不同增香施肥处理香稻籽粒中的香气风味挥发物（如醛类、烯类和酮类）组分存在显著差异。

The effects of two fragrance-enhancing fertilization treatment T1(conventional fertilization mode with fragrance enhancer 1), T2(fragrance-enhancing special fertilizer for aromatic rice) and conventional fertilization mode (CK) on the yield, quality, and aroma volatile compounds of the fragrant rice variety Qingxiangyou 19 xiang were tried in the field. The results indicated that, compared to CK, both T1 and T2 treatments significantly increased the yield of Qingxiangyou 19 xiang by 9.94% and 11.94%, respectively, while also improved the brown rice rate, milled rice rate, and whole milled rice rate, significantly increased the content of 2-acetyl-1-pyrroline (2-AP) in the grains by 11.11% and 33.83%. The significant differences were observed in the composition of aroma volatile compounds (such as aldehydes, alkenes, and ketones) in the grains of Qingxiangyou 19 xiang by different fragrance-enhancing fertilizer treatments.
