CO2是植物光合作用的原料,氮素是影响植物生长发育最为活跃的营养因素,两者对作物的生长发育以及最终产量形成和品质优劣的影响最大。现通过总结国内外对“CO2浓度倍增与介质施氮对冬小麦物质生产及氮素利用的影响”的研究进展,以综述形式,分别从大气CO2浓度增加与介质施氮水平对冬小麦光合特性、籽粒产量、氮代谢等三个方面的影响做以简单归纳介绍并提出需进一步深入研究的问题,以期为今后的研究工作提供一定的发展方向和思路。
CO2 is the raw material for plant photosynthesis. Nitrogen is the most active nutrient that affects plant growth and development. Both of them have the greatest impact on crop growth and development as well as the final yield formation and quality. By summarizing the research progress at home and abroad about the effects of doubled CO2 concentration and nitrogen application on the material production and nitrogen utilization of winter wheat, the paper summarized the effects of CO2 concentration and nitrogen application on the photosynthetic characteristics of winter wheat , Grain yield and nitrogen metabolism in order to briefly summarize and propose the issues to be further studied, with a view to provide some directions and ideas for the future research work.
