Abstract

Abstract:

【Objective】 To study the effects of different nitrogen inhibitors on the growth, development, nitrogen utilization, and yield of cotton when nitrogen fertilizer is added. The purpose is to determine the appropriate concentration of nitrogen inhibitors. 【Methods】 A pot experiment was conducted using 'China Cotton Research Institute 100' cotton plants. Under the same nitrogen application level, four types of nitrogen inhibitors, 3,4-dimethylpyrazole phosphate (DMPP), 2-chloro-6-trichloromethylpyridine (CP), dicyandiamide (DCD), and N-butylthiophosphoric triamide (NBPT) were added. And two different concentrations were used for each nitrogen inhibitor. The inhibitors were applied as base fertilizer and topdressing during the flowering period, along with urea. Cotton agronomic traits, biomass quality, nitrogen accumulation, lint cotton yield, and nitrogen fertilizer utilization were compared. 【Results】 Compared to the treatment with urea alone, the cotton plants treated with nitrogen inhibitors had a 6.5% to 16.8% increase in individual plant biomass quality during the flowering period, and a 8.8% to 33.0% increase in individual plant lint cotton yield. The apparent nitrogen fertilizer utilization rate increased by 4.5 to 15.1 percentage points. Among the treatments, cotton treated with 0.5% dicyandiamide (DCD), 0.25% 2-chloro-6-trichloromethylpyridine (CP), 1.0% 3,4-dimethylpyrazole phosphate (DMPP), and 0.5% N-butylthiophosphoric triamide (NBPT) added to urea showed better results in terms of biomass accumulation, nitrogen fertilizer utilization, and yield compared to cotton treated with 1.0% DCD, 0.5% CP, 2.0% DMPP, and 1.0% NBPT added to urea. 【Conclusion】 Cotton plants treated with 0.5% DCD added to urea have the highest individual plant biomass accumulation, and cotton treated with 0.25% CP added to urea shows better increases in cotton yield and nitrogen fertilizer utilization compared to other nitrogen inhibitors treatments.

摘要：

【目的】研究氮肥添加不同氮素抑制剂对棉花生长发育、氮素利用与产量的影响,获得不同氮素抑制剂适宜的添加浓度。【方法】采用盆栽试验,以中棉所100为材料,共设10个处理,在同一施氮水平下,添加3,4-二甲基吡唑磷酸盐(DMPP)、2-氯-6-三氯甲基吡啶(CP)、双氰胺(DCD)与N-丁基硫代磷酰三胺(NBPT)等4种氮素抑制剂,每种氮素抑制剂设置2个浓度,分底肥和开花期追肥与尿素一起施入,比较棉花农艺性状、干物质积累量、氮素积累量、籽棉产量以及氮肥利用率。【结果】与单施尿素处理相比,添加氮素抑制剂处理的棉花收获期单株干物质积累量增加了6.5%~16.8%,棉花单株籽棉产量增加了8.8%~33.0%,氮肥表观利用率增加了4.5~15.1个百分点。尿素添加0.5%DCD、0.25%CP、1.0%DMPP与0.5%NBPT处理棉花干物质积累量、氮肥利用率与产量分别优于尿素添加1.0%DCD、0.5%CP、2.0%DMPP与1.0%NBPT处理。【结论】尿素添加0.5%DCD处理的棉花单株干物质积累量最高,尿素添加0.25%CP处理较其他氮素抑制剂处理提高棉花产量与氮肥利用率效果较佳。
