| 1 | 新株型水稻的光合效率显示文摘新株型(NPT)水稻的净光合速率(Pn)明显低于常规籼稻。叶绿素荧光分析表明,新株型水稻的原初光化学效率(Fv/Fm)明显高于常规籼稻;但是从单位叶绿素的饱和净光合速率、遮荫试验结果及PSII的光化学淬灭系数来看,新株型水稻的实际光能利用效率较常规籼稻低。这表明非光化学过程是限制新株型水稻光合作用的主要限制因素。作者从光能利用效率的角度讨论了新株型水稻的生理改良问题。 | 胡文新 彭少兵 高荣孚 J. K. Ladha | 2005 | 中国农业科学2005，38，11： | 20 |

| 5 | A NEW APPROACH TO HOLISTIC NITROGEN MANAGEMENT IN CHINA显示文摘Since the 1980s,the widespread use of N fertilizer has not only resulted in a strong increase in agricultural productivity but also caused a number of environmental problems,induced by excess reactive N emissions.A range of approaches to improve N management for increased agricultural production together with reduced environmental impacts has been proposed.The 4R principles(right product,right amount,right time and right place)for N fertilizer application have been essential for improving crop productivity and N use efficiency while reducing N losses.For example,site-specific N management(as part of 4R practice)reduced N fertilizer use by 32%and increased yield by 5%in China.However,it has not been enough to overcome the challenge of producing more food with reduced impact on the environment and health.This paper proposes a new framework of food-chainnitrogen-management(FCNM).This involves good N management including the recycling of organic manures,optimized crop and animal production and improved human diets,with the aim of maximizing resource use efficiency and minimizing environmental emissions.FCNM could meet future challenges for food demand,resource sustainability and environmental safety,key issues for green agricultural transformation in China and other countries. | Xuejun LIU Zhenling CUI Tianxiang HAO Lixing YUAN Ying ZHANG Baojing GU Wen XU Hao YING Weifeng ZHANG Tingyu LI Xiaoyuan YAN Keith GOULDING David KANTER Robert HOWARTH Carly STEVENS Jagdish LADHA Qianqian LI Lei LIU Wim DE VRIES Fusuo ZHANG | 2022 | Frontiers of Agricultural Science and Engineering2022，9，3： | 2 |
