个人简介
20116月获得农学博士学位,博士论文题目为:氮素营养对水稻光合作用与光合氮素利用率的影响机制研究,2014年获全国百篇优秀博士学位论文。课题组长期从事作物矿质养分(NPK等)、光合作用和逆境胁迫(温度和干旱)之间的互作关系,运用分子生理、光合模型、形态解剖学和全基因组分析等手段阐明作物高产、稳产与资源高效利用的限制因素及调控途径。主要学术成果如下:(1)运用光合模型阐明气孔导度、叶肉导度和Rubisco酶活性是限制水稻光合作用和氮肥利用效率的主要原因,同时在国际上首次提出,筛选或培育叶绿体体积小、数目多的品种将有助于提高水稻的氮素利用率和产量;(2)运用植物形态解剖学阐明气孔大小能够调控气孔响应外界环境刺激(光照)的能力,叶片厚度和密度、细胞壁厚度、叶绿体发育等能够通过调控叶肉导度来影响光合作用和氮素利用效率;(3)运用光合模型和最优化气孔模型阐明了水稻和小麦光合作用、气孔导度和叶肉导度对温度适应性的差异和机理,在全球气候变暖的背景下,为提高作物温度适应性提供理论支撑。
