新的稻米品种将甲烷排放量削减70%,帮助减缓气候变化。 New rice strain cuts methane emissions by up to 70%, aiding in climate change mitigation.

科学家开发了一种新的稻株,比传统品种排放的甲烷少70%,有可能显著减少全球甲烷排放量。 Scientists have developed a new rice strain that emits up to 70% less methane than traditional varieties, potentially cutting global methane emissions significantly. 稻米种植约占全球甲烷排放量的12%。 Rice farming contributes about 12% of global methane emissions. 研究人员将高产稻米与低排放品种交叉,查明稻米根中影响甲烷释放的关键化学化合物。 Researchers crossbred high-yield rice with low-emitting varieties, identifying key chemical compounds in rice roots that affect methane release. 这种新的“低肥和高乙醇”(LFHE)大米不仅减少排放,而且保持高产量,平均每公顷8.96吨。 This new "low fumarate and high ethanol" (LFHE) rice not only reduces emissions but also maintains high yields, averaging 8.96 tons per hectare. 发展的目的是应对气候变化和人口增长导致的甲烷排放量增加。 The development aims to combat increasing methane emissions due to climate change and population growth.
