摘要
杂交粳稻作为中国北方稳产保供的重要作物,其高产优质高效栽培技术的创新关乎粮食安全与农业可持续发展。近年来,通过杂种优势利用等手段已培育出辽优、天隆优等系列高产优质品种,结合水肥精准调控与抗逆栽培技术,实现了杂交粳稻产量和品质的提升。然而,杂种优势不强、抗逆性状协同性差等问题的存在,制约着北方杂交粳稻生产潜力发挥。基于现有文献和近年来的生产实践经验,归纳了北方杂交粳稻的高产优质高效栽培技术,剖析了其面临的挑战,并展望了未来的发展方向,以期为相关研究和生产实践工作提供参考。
Japonica hybrid rice serves as a critical crop for ensuring the grain's stable production and supply in northern China.The innovations in high-yield,high-quality,and high-efficiency cultivation techniques for japonica hybrid rice are associated with grain security and the sustainable development of agriculture.In recent years,the application of heterosis and other approaches has enabled the breeding of elite varieties(e.g.,Liaoyou and Tianlongyou series),which,combined with precision irrigation,fertilization management,and stress-resilient agronomic practices have enhanced both the yield and grain quality of japonica hybrid rice.Nevertheless,persistent challenges including limited heterosis expression and suboptimal synergy among stress-tolerant traits constrain the yield potential of japonica hybrid rice in northern China.This article summarizes the high-yield,high-quality,and high-efficiency cultivation techniques for japonica hybrid rice in northern China through a review of literature and field trial data,identifies the existing challenges,and proposes future research priorities,aiming to provide references for related research and farming practices.
