通过不同施肥时期试验,研究不同施肥时期对不同穗型品种品质和产量的的影响,为生产优质、高产的稻米提供技术指导。本研究采用大田小区试验,通过分析供试品种的5项品质指标,最终确定最佳的施肥处理。研究表明,穗数型品种品质最优、产量最高的处理为分底肥、蘖肥和粒肥3次施入的处理,食味评分比其他处理食味评分高4分,增产34.3%;穗重型品种‘系选1号’品质最优、产量最高的处理为分底肥、蘖肥、穗肥和粒肥4次施入的处理,比其他处理食味评分高7分,增产22.6%。
The effects of different fertilization periods on the quality and yield of different panicle varieties were studied through different fertilization periods to provide technical guidance for the production of high quality and high yield rice. In this study, field trials were conducted to determine the best quality fertilization treatments by analyzing five quality indicators of the tested cultivars. The results showed that the spike number was the best quality and the highest yield was treated three times by basal fertilizer, tillering fertilizer and granule fertilizer. The score of the taste score was 4 points higher than that of other treatments, and the yield was 34.3% The results showed that the best quality and highest yield of treatment 1 was the treatment with 4 treatments of bottom fertilizer, tillering fertilizer, panicle fertilizer and granulation fertilizer, which was 7% higher than the other treatments and 22.6% more yield.
