摘要：

研究不同氮肥运筹对优质杂交稻华浙优210产量、氮肥利用效率以及稻米品质的影响,以期明确其最佳的基、蘖、穗肥的施用比例。2022年在衢州市柯城区开展大田试验,以优质杂交稻华浙优210为材料,在总施氮量180 kg·hm-2的基础上,按基肥∶蘖肥∶穗肥施用比例设置3种施肥方案,并以不施用氮肥为对照(CK),研究不同氮肥运筹对水稻产量、氮肥利用效率以及稻米品质的影响。结果表明,氮肥运筹对水稻产量、氮肥利用效率以及稻米品质均有显著影响。不同施氮处理间,产量与氮肥利用效率均以N2与N3处理最高。就品质而言,N2处理的糙米率显著高于其他处理;垩白粒率、垩白度以及稻米蛋白质含量均表现为N3最高,N1与N2次之,CK最低;胶稠度则表现为CK最高,N1与N2次之,N3最低。综合考虑产量、氮肥利用效率与稻米品质,N2处理是优质杂交稻华浙优210较为理想的氮肥运筹方式。

Abstract:

To clarify the optimal application ratio of base, tiller and panicle fertilizer, this study investigated the effects of different nitrogen fertilizer management strategies on the yield, nitrogen use efficiency and grain quality of high-quality hybrid rice variety Huazheyou 210. In 2022, a field experiment was conducted in Kecheng District, Quzhou City. Huazheyou 210 was used as the test material. Based on a total nitrogen application rate of 180 kg·hm-2, three fertilizer application schemes were established in terms of base fertilizer∶tiller fertilizer∶panicle fertilizer ratios, with a control group that did not receive any nitrogen fertilizer (CK). The results indicated that nitrogen fertilizer management had a significant impact on rice yield, nitrogen use efficiency and quality. Among the different nitrogen application treatments, N2 and N3 treatments achieved the highest yield and nitrogen use efficiency. In terms of rice quality, the brown rice rate of N2 treatment significantly outperformed other treatments. Chalky grain rate, chalkiness degree, and rice protein content were highest in the N3 treatment, followed by N1 and N2, while the CK treatment had the lowest values. Gel consistency showed the highest value in CK treatment, followed by N1 and N2, and the lowest in the N3 treatment. Considering the yield, nitrogen use efficiency and rice quality, N2 treatment was an optimal nitrogen fertilizer management method for high-quality hybrid rice Huazheyou 210.

Key words: high-quality rice, nitrogen fertilizer management, yield, quality
