Abstract

Abstract:

Using Suigeng 18 as the test material, a two-year field experiment was conducted to explore and optimize the application methods of polyaspartic acid urea and conventional urea on nitrogen balance and rice yield. The results showed that compared with the control without fertilization, the application of polyaspartic urea （in two and four applications） and the conventional urea in four applications significantly increased the dry matter mass and nitrogen content of rice panicles, culm and leaves, and reduced soil NO₃^- and NH₄⁺ leaching, Among them, the treatment with four applications of polyaspartic urea had the best effect, showing the highest for the nitrogen concentrations in grains and milled rice, effective panicle number, total grain number as well as other indicators, and the rice yield was significantly increased by 10.24% to 48.07% in 2019 and 18.95% to 51.91% in 2020 compared with other treatments.

摘要：

以绥粳18号为试验材料,进行2年的田间试验,探索优化聚天冬氨酸尿素和常规尿素的施用方式对寒地水稻氮素吸收和产量的影响。结果表明,与不施肥对照相比,施用聚天冬氨尿素（分2次和4次施用）和常规尿素分4次施皆显著提高了水稻穗、茎、叶的干物质量及氮素含量,并降低了土壤NO₃^--N和NH₄⁺-N的淋溶。其中,以聚天冬氨尿素分4次施的处理效果最佳,其籽粒氮含量、精米氮含量及有效穗数、总粒数等指标皆最高,稻谷产量较其他处理显著提高10.24%~48.07%（2019年）和18.95%~51.91%（2020年）。
