摘要:

本研究探讨了在常规施肥与减氮15%条件下,增施氢氧化镁功能型中量元素肥料对晚稻甬优1540产量性状、农艺性状、氮素吸收及稻米品质的影响。结果表明,与常规施氮处理相比,增施氢氧化镁功能型中量元素肥料可通过提高每穗颖花数和有效穗数来增加水稻产量,其中每667 m2施用10 kg的增产效果优于5.0 kg;即使在减氮15%条件下,仍能维持较高的产量水平。此外,增施该镁肥可降低垩白粒率、提高胶稠度,从而改善稻米加工品质与营养品质。综合而言,建议在常规施肥减氮15%的基础上,每667 m2配施5.0~10.0 kg氢氧化镁功能型中量元素肥料,可在提升水稻产量的同时改善稻米品质,该肥料宜作为基肥尽早施用。

Abstract:

This study investigated the effects of applying a functional magnesium hydroxide meso-element fertilizer under conventional nitrogen fertilization and 15% nitrogen reduction on yield traits,agronomic traits,nitrogen uptake,and grain quality of late rice variety Yongyou 1540. The results showed that compared with conventional nitrogen application,the addition of the magnesium hydroxide meso-element fertilizer increased rice yield by raising the number of spikelets per panicle and effective panicles,with the application rate of 10 kg per 667 m2 performing better than 5.0 kg. Even under the 15% nitrogen reduction condition,a relatively high yield level was maintained. In addition,the application of this magnesium fertilizer reduced chalky grain rate and increased gel consistency,thereby improving rice processing and nutritional quality. In summary,it is recommended to apply 5.0-10.0 kg of the functional magnesium hydroxide meso-element fertilizer per 667 m2 on the basis of conventional fertilization with 15% nitrogen reduction,which can both enhance rice yield and improve grain quality. The fertilizer should be applied as a basal dose as early as possible.
