摘要
该研究的目的是确定到2050年气候变化的预期产量、氮素(NUE)利用效率、N淋溶、N2O和NH3排放。该研究使用了1991-2010年、2011-2030年和2031-2050年的DNDC模型以及波兰的10个地点进行。在模拟中,考虑作物轮作:玉米作粮-春大麦-冬油菜-冬小麦,分别在轻、中、重土壤上种植,施肥分别为:140、90、160和120 kg N ha-1。结果表明,气候变化对玉米(6-43%)和冬油菜(2-8%)产量的影响较大,对冬小麦(- 18% ~ -5%)产量的影响较小,对春大麦的影响较小。玉米的氮肥利用效率会增加(2-17%),冬小麦和春大麦的氮肥利用效率会减少(3-22%),而油菜的氮肥利用效率不会改变。氮素利用效率变化和氮素损失不影响未来栽培中减少施氮量的需要。
Wpływ zmian klimatu na efektywność wykorzystywania azotu oraz jego straty
The aim of the study was to determine the expected yields, the efficiency of N (NUE) use, N leaching, N2O and NH3 emissions depending on climate change until 2050. The research was carried out using the DNDC model for the years 1991-2010, 2011-2030 and 2031-2050 as well as 10 locations in Poland. In the simulations, the crop rotation were considered: maize for grain - spring barley - winter rape - winter wheat, which was grown on light, medium and heavy soils, with fertilization of, respectively: 140, 90, 160 and 120 kg N ha-1. It was found that climate change can contribute to increase in the yield of maize (6-43%) and winter rape (2-8%), decreases in winter wheat yield (from -18 to -5%) and negligible changes in yields of spring barley. NUE will increase in the cultivation of maize (2-17%), it will decrease in winter wheat (3-22%) and spring barley (3-17%) crops and will not change in the case of winter oilseed rape. NUE changes and N losses did not affect the need to reduce nitrogen doses in the future cultivation of the studied plants.
