一个国际团队在最新一期英国《自然·气候变化》上报告说,现有粮食作物产出受气候变化影响在未来10年可能会下降,各国有必要加速培育能更好适应新气候条件的粮食作物品种并尽快开展种植,以确保粮食供应稳定。研究人员主要对非洲种植的玉米在气候变化影响下的生长状况进行了分析。他们研究了升温效应对玉米生长周期(即从播种到收成的间隔时间)的影响,结果发现温度越高,这一周期 An international team reported in the latest issue of Climate Change in the UK that the current output of food crops is likely to decline over the next 10 years due to the effects of climate change and that countries need to speed up the cultivation of food that can better adapt to the new climatic conditions Crop varieties and planting as soon as possible to ensure a stable food supply. The researchers mainly analyzed the growth of maize grown in Africa under the influence of climate change. They studied the effect of warming on the corn growth cycle (ie, the interval from planting to harvest) and found that the higher the temperature, the period
