Abstract

Abstract: The effects of sowing dates［conventional sowing date（S1）and delayed sowing date（S2）］and enhancing fragrance fertilizer［no enhancing fragrance fertilizer（conventional fertilization，F1） and enhancing fragrance fertilizer（F2）］ on yield，quality and fragrance of major aromatic rice varieties ［Yexiangyouyousi（V1），19xiang（V2）and Huaxiaxiangsi（V3）］were studied in Hubei Province，so as to provide a scientific basis for the production of high‑quality fragrant rice. The results showed that the high temperature and heat damage could be avoided or alleviated by delaying the sowing date，and the initial heading stage was postponed to mid‑to‑late August after delaying the sowing date.The processing quality and appearance quality of aromatic rice improved，and the content of aromatic substance 2‑AP in brown rice significantly increased by 12.14%—162.84% after delaying the sowing date.The processing quality of aromatic rice could be improved by adding enhancing fragrance fertilizer，but the appearance quality was slightly affected.Meanwhile，the content of aroma substance 2‑AP in brown rice could be increased by 6.19%—40.60%.Daily maximum temperature was negatively correlated with chalky grain rate and chalkiness，total rainfall was extremely positively correlated with yield and 2‑AP content in brown rice，and daily maximum temperature，daily minimum temperature and days of daily maximum temperature≥35 ℃ were extremely negatively correlated with 2‑AP content in brown rice. Overall，delayed sowing date and enhancing fragrance fertilizer are beneficial to improving the processing quality and enhancing fragrance，but the enhancing fragrance fertilizer needs to be properly combined according to the characteristics of aromatic rice varieties and sowing date to achieve better results.

Key words: Aromatic rice, Sowing date, Enhancing fragrance fertilizer, Yield, Fragrance, Quality

摘要： 研究播期［常规播期（S1）和推迟播期（S2）］和增香肥［不施增香肥（常规施肥，F1）和施增香肥（F2）］对湖北省主要香稻品种［野香优油丝（V1）、19香（V2）、华夏香丝（V3）］产量、品质和香味的影响，为优质香稻保优增香生产提供理论依据。结果表明，推迟播期后，始穗期推迟至8月中下旬，可以避免或减轻高温热害，香稻加工品质和外观品质有所改善，同时总体上显著增加糙米中香气物质2-AP含量，增加幅度为12.14%~162.84%；施增香肥也可改善香稻加工品质，但略微影响外观品质，同时也能增加糙米中香气物质2-AP含量，增加幅度为6.19%~40.60%；日最高气温与垩白粒率和垩白度均呈显著负相关，总降雨量与产量和糙米中香气物质2-AP含量均呈极显著正相关，而日最高气温、日最低气温和日最高气温≥35 ℃天数与糙米中香气物质2-AP含量均呈极显著负相关。综上，推迟播期和施用增香肥均有利于改善香稻加工品质，增加香味，但增香肥还需根据香稻品种特性及播期进行合理配施，才能达到较好的效果。
