摘要: 【目的】研究控失尿素、普通尿素不同配比对棉花生长发育、氮素吸收及产量的影响。【方法】田间小区试验,试验设8个处理,(1)CK:不施氮肥;(2)常规尿素:施N 225 kg/hm2;(3)等氮量控失尿素:施N 225 kg/hm2;(4)控失尿素减量20%:施N 180 kg/hm2;(5)控失尿素减量30%:施N 157.5 kg/hm2;(6)控失尿素与常规尿素7∶3配比:施N 225 kg/hm2;(7)控失尿素与常规尿素5∶5配比:施N 225 kg/hm2;(8)控失尿素与常规尿素3∶7配比:施N 225 kg/hm2,测定棉花干物质、氮素吸收量和产量,明确棉花干物质、氮素吸收、产量与控失尿素配施常规尿素的关系。【结果】与常规尿素相比,控失与常规尿素7∶3配比能显著增加棉花干物质量,提高棉花产量,增产14.34%;提高棉花氮肥利用率,氮肥利用率增加了10.2百分点;控失尿素减量20%处理与常规尿素处理的棉花干物质与产量大体相同,控失尿素减量30%处理显著低于常规尿素处理,产量降低了5.85%;控失尿素减量20%处理与常规尿素处理的棉花N素吸收量大体相同,但大幅度提高了氮肥利用率,利用率增加了11.26百分点。【结论】用控失尿素和控失尿素与常规尿素配施均提高棉花氮肥利用率,其中控失与常规尿素7∶3配比效果最好。

Abstract: 【Objective】 The effects of different ratios of loss-control urea and common urea on cotton growth, nitrogen uptake and yield were studied through field plot experiments.【Method】 Eight treatments were designed to research the effects of loss-control urea and common urea on accumulation rate for plant dry matters, nitrogen uptake and yield of cotton,they were CK (N 0 kg/hm2), conventional urea (N 225 kg/hm2), loss-control urea (N 225 kg/hm2), 80% loss-control urea (N 180 kg/hm2), 70% loss-control urea (N 157.5 kg/hm2), 70% loss-control urea + 30% conventional urea (total of N 225 kg/hm2), 50% loss-control urea + 50% conventional urea (total of N 225 kg/hm2), 30% loss-control urea + 70% conventional urea (total of N 225 kg/hm2).【Result】 The results showed that compared to the loss-control urea and common urea treatments, the application of 70% loss-control urea + 30% common urea could significantly increase the plant dry matters and yield of cotton by 14.34%, increase fertilizer nitrogen use efficiency by 10.2 percentage point; the treatments of 80% loss-control urea and common urea did nearly the same to the plant dry matters and yield of cotton, compared with the common urea, the treatment of 70% loss-control urea could significantly reduce the yield of cotton by 5.85%; the treatment of 80% loss-control urea could significantly increase the fertilizer nitrogen use efficiency of cotton by 11.26 percentage point.【Conclusion】 The application of loss-control urea combined with conventional urea increased the utilization rate of nitrogen fertilizer in cotton, and the 7∶3 ratio of loss-control urea and conventional urea was the best.
