本网讯（南方粮油作物协同创新中心PI 张振华）“南方粮油作物协同创新中心”PI张振华博士领衔的创新团队研究结果表明：稻油轮作系统具有显著的增产增效作用，冬季轮作油菜是实现粮油作物可持续发展的有效举措。近年来，创新团队获得国家自然科学基金等省部级以上科研项目38项；授权国家发明专利7项，发表科研论文46篇，其中SCI论文25篇，2篇发表在世界顶尖专业期刊Plant Physiology，10篇发表在研究领域TOP期刊，如Soil Biology and Biochemistry，Plant and Soil和Biology and Fertility of Soil等，充分阐明了长江中下游地区稻油轮作系统对农田土壤质量和粮油作物生产的提质增效优势。研究表明；相比于其它轮作方式，冬季轮作油菜可以显著改善稻田土壤质量、提高根际土壤微生物种群数量、提高土壤养分有效性，最终可以使次年水稻增产5-15%（Biology and Fertility of Soil，2018）。

在前期研究工作的基础上，该团队于2018年10月18日在国际顶尖刊物Plant Physiology再次发文阐述稻油轮作系统提质增效机理[NRT1.1-related NH₄⁺ toxicity in Arabidopsis is associated with disturbed balance between NH₄⁺ uptake and assimilation. Plant Physiology, 2018, http://www.plantphysiol.org/content/early/2018/10/18/pp.18.00410]。该论文针对影响稻田油菜养分高效利用的渍害问题开展研究，充分阐明了植物是如何通过信号调控C-N代谢平衡和铵态氮吸收来影响植物对铵毒害的耐受性的，研究结果为提高稻田渍害条件下的油菜氮素养分利用效率提供了理论支撑。
