摘要

在IPCC(政府间气候变化专门委员会)提出的第四种气候情景下,假设温室气体排放水平非常高(RCP“代表性浓度路径”8.5),对2080年和2099年的气候变化进行了建模方程;预测低施肥或不施肥和高施肥玉米产量,作为适应和减缓气候变化不利影响的一种技术。到2080年,低施或不施化肥使玉米减产的百分比为30%至55%,施用大量化肥使玉米减产的百分比为10%至20%。气候变化将对未来的农业生产和粮食安全产生负面影响。施肥是应对气候变化的玉米种植减缓和适应策略之一。

FERTILIZACIÓN COMO ESTRATEGIA DE MITIGACIÓN Y ADAPTACIÓN DEL CULTIVO DE MAIZ PARA FUTUROS CAMBIOS CLIMÁTICOS
A modeling equation was carried out for climate changes in 2080 and 2099 under the fourth climate scenario proposed by the IPCC (Intergovernmental Panel on Climate Change) where a very high level of greenhouse gas emissions is assumed (RCP “Representative Concentration Pathway” 8.5); to predict the yield of corn production with low or no fertilization and high fertilization as a technique for adaptation and mitigation of the adverse effects of climate change. The percentage reduction in corn yield by 2080 with low or no fertilizer application is 30 to 55%, and with high fertilizer application it is 10 to 20%. Climate change would have negative impacts on future agricultural production and food security. Fertilization is one of the mitigation and adaptation strategies for corn cultivation in the face of climate change.
