为评估不同栽培措施对水稻基肥氮素利用率和产量的影响,本研究以水稻品种玮两优8612为试验材料,利用¹⁵N标记示踪技术分析不同栽培措施下水稻产量、植株氮素的吸收和转化率以及土壤酶活性。结果表明,改良灌溉管理和优化施肥策略有利于增加水稻植株氮素的积累与吸收,增加产量,其中轻干湿交替灌溉配合有机肥的综合管理措施（ZGC-3）效果较佳;此外,综合管理措施有利于提高土壤酶活性,增强土壤生物化学活性。研究证实了综合栽培管理措施可有效提升水稻产量和氮肥利用效率,以及减少对环境影响。

To evaluate the effects of different cultivation measures on the nitrogen utilization efficiency of basal fertilizer and rice yield base fertilizer, the rice variety Weiliangyou 8612 was used as the experimental material, and the rice yield, plant nitrogen absorption and conversion rate, and soil enzyme activity under different cultivation measures were analyzed using ¹⁵N labeling and tracing technology. The results showed that improving irrigation management and optimizing fertilization strategies were beneficial for increasing nitrogen accumulation and absorption in rice plants, and increasing yield. Among them, the comprehensive management measure of light dry wet alternation irrigation combined with organic fertilizer（ZGC-3）had the better effect. In addition, comprehensive management measures are beneficial for improving soil enzyme activity and enhancing soil biochemical activity. The study confirmed the effectiveness of comprehensive cultivation management strategies in improving rice yield and nitrogen fertilizer utilization efficiency, as well as reducing environmental impact.
