摘要：

为明确水稻品种嘉禾香1号在杭州市余杭区的产量与品质表现,于2022年和2023年分别设置不同施肥方式开展对比试验。结果表明,2022年,处理1(有机缓控释肥一次性基施)虽有利于促进前期分蘖,但不利于后期成穗;处理2(有机缓控释肥减量分2次施用)对前期分蘖和后期成穗均无促进作用。处理4(无机复合肥分2次施用)在穗数、每穗总粒数、每穗实粒数和千粒重方面表现较优,产量最高;处理3(无机复合肥分3次施用)次之,但其垩白度和垩白粒率最低,垩白度级别和透明度级别均为一等,直链淀粉含量最低且级别为一等,蛋白质含量也最低,综合品质较好。2023年,处理6(无机复合肥增氮)产量最高,处理5(有机缓控释肥“一基一追”)次之,处理4最低;处理5的精米率和整精米率最高,垩白度最低,加工品质和外观品质较优。综上,2022年采用无机复合肥分3次施用,或2023年采用好乐耕有机缓控释肥“一基一追”方式,均有利于提升嘉禾香1号的综合品质。本研究为该品种在余杭区的推广种植提供了理论依据。

Abstract:

To clarify the performance of yield and quality of rice cultivar Jiahexiang 1 in Yuhang District, Hangzhou City, a comparative experiment with different fertilization methods was conducted in 2022 and 2023, respectively. The results showed that in 2022, treatment 1 (basal application of controlled-release organic fertilizer) promoted early tillering but was unfavorable to panicle formation at later stages. Treatment 2 (reduce application rate of controlled-release organic fertilizer in 2 splits) showed no promotion effect on either early tillering or late panicle formation. Treatment 4 (applying inorganic compound fertilizer in 2 splits) exhibited superior performance in panicle number, total grains per panicle, filled grains per panicle, and 1 000-grain weight, resulting in the highest yield. Treatment 3 (applying inorganic compound fertilizer in 3 splits) ranked second in yield, however, it showed the lowest chalkiness degree and chalky grain rate, with both chalkiness and transparency grades reaching the first class. It also had the lowest amylose content (first-class grade) and the lowest protein content, indicating better comprehensive quality. In 2023, treatment 6 (applying inorganic compound fertilizer with increased nitrogen rate) achieved the highest yield, followed by treatment 5 (“one basal plus one topdressing” application of controlled-release organic fertilizer), while treatment 4 had the lowest yield. Treatment 5 showed the highest brown rice rate and milled rice rate, as well as the lowest chalkiness degree, indicating relatively better processing and appearance quality. In conclusion, applying inorganic compound fertilizer in 3 splits in 2022 or using the “one basal plus one topdressing” method with Haolegeng controlled-release organic fertilizer in 2023 helped Jiahexiang 1 improve the comprehensive quality. This study provides a theoretical basis for the promotion and cultivation of this rice cultivar in Yuhang District.
