摘要

摘要: 目的利用控失尿素开展宁夏引黄灌区水稻化肥减量研究，为提高宁夏引黄灌区水稻产量，减少氮素损失，促进氮素环保高效施用提供数据参考。方法通过田间试验，以不施氮肥（CK）和常规尿素为对照，设控失常量、控失减量10%、控失减量20%、控失 ∶ 常规为7 ∶ 3、控失 ∶ 常规为5 ∶ 5、控失 ∶ 常规为3 ∶ 7、控失尿素（基）等7个处理，研究不同控失尿素减量配比处理对水稻产量、氮素吸收利用和淋失的影响。结果（1）施用控失尿素能够促进水稻增产，控失 ∶ 常规为5 ∶ 5处理的水稻增产效果最好，比常规尿素增产8.92%，其次为控失 ∶ 常规为7 ∶ 3。控失尿素主要增加水稻的穗粒数进而增加产量。（2）施用控失尿素能够促进水稻氮肥利用率，控失减量10%处理的氮肥利用率最高，比常规尿素增加了9.79个百分点，其次为控失 ∶ 常规为5 ∶ 5处理。（3）施用控失尿素能够降低稻田田面水总氮浓度和总氮淋失量。与常规尿素相比，控失尿素各处理整个水稻生育期全氮淋失量降低了28.40%～66.32%，其中，控失减量20%处理氮素淋失降低幅度最大，其次为控失减量10%、控失常量处理。结论控失尿素可以显著提高水稻的产量与氮肥利用率，降低氮素淋失量。综合考虑，施用控失尿素243～270 kg N·hm⁻²、控失尿素与常规尿素配比5 ∶ 5是宁夏引黄灌区较合理的氮素运筹模式。

Abstract: Objective The loss control urea (LCU) that, when dissolved in water, couples in a network structure to mitigate ammonia volatilization and N leaching in rice field fertilization was studied for its practical applications. Method A plot experiment in the field was conducted with varied applications of LCU to determine the resulting rice yield and N utilization efficiency (NUE) as well as the N loss through leaching. In addition to control without N fertilization (CK), the treatments included applications of the conventional urea (CU), recommended LCU usage, 10% reduced LCU usage, 20% reduced LCU usage, LCU/CU at 7 ﹕ 3 ratio, LCU/CU at 5 ﹕ 5 ratio, LCU/CU at 3 ﹕ 7 ratio, and LCU by basal application. Result (1) All LCU applications improved the rice yield over CK. The largest increase of 8.92% over CU was resulted from the mixture of LCU/CU at 5 ﹕ 5 ratio. LCU/CU at 7 ﹕ 3 mixing ratio produced the second highest yield gain. The gains on rice yield was mainly attributed by the increase of the grain count per panicle. (2) LCU significantly improved NUE of the rice plants. By reducing 10% on the LCU usage, the highest NUE with an increase of 9.79 over CU was observed among all applications. That was followed by the second highest delivered by LCU/CU at 5 ﹕ 5 ratio. (3) LCU significantly reduced the total N concentration in surface water and N loss from leaching. In comparison to CU, depending upon the application rate, LCU reduced 28.40%–66.32% of the N loss from leaching in an entire rice growth period. By reducing 20% on the LCU usage, the highest N loss from leaching reduction was observed, followed by 10% reduced LCU usage, and then the CU treatment. Conclusion LCU significantly improved the yield and NUE of rice plants and reduced the N loss from leaching in soil. The application of LCU at 243–270 kg ·hm⁻² N with a 5 ﹕ 5 mixing ratio with CU was recommended for the rice farming in the Yellow River irrigation region.
