科学家创造固氮小麦,减少对合成肥料的需求。 Scientists create nitrogen-fixing wheat, reducing need for synthetic fertilizers.

研究人员开发了一种经基因改变的小麦菌株,能够固定自己的氮,减少对合成化肥的依赖。 Researchers have developed a genetically modified strain of wheat capable of fixing its own nitrogen, reducing reliance on synthetic fertilizers. 这一突破是通过使植物能够从根源上吸收固氮细菌而取得的,在早期试验中显示出希望,低氮土壤的生长有所改善。 The breakthrough, achieved by enabling the plant to host nitrogen-fixing bacteria in its roots, shows promise in early trials with improved growth in low-nitrogen soils. 如果证明安全和有效,这项创新可以降低耕作成本,减少化肥径流造成的污染,减少温室气体排放。 If proven safe and effective, the innovation could lower farming costs, cut pollution from fertilizer runoff, and reduce greenhouse gas emissions. 该技术仍处于实验阶段,商业用途可能要等几年才开始。 The technology is still experimental, with commercial use likely years away.
