浅析CO_2浓度升高对小麦的影响

The effect of elevated concentration of carbon dioxide on wheat

目的了解近来年CO2浓度升高对小麦生长产生的重要影响。方法参考大量文献,分别从生长、生理和品质3个方面阐述了CO2浓度升高对小麦影响的研究进展。结果首先,CO2浓度一定范围内的升高属于施肥效应,促进了作物的生长、提高了叶片的光合作用、降低了呼吸作用,提高了小麦的产量;其次,CO2浓度升高对小麦的品质产生了重要的影响;最后,指出了研究的重点,对以后的研究方向提供了思路。结论可以结合前人研究结果,利用CO2浓度增加的肥料效应,使用一定手段来提高小麦的产量和品质。

Objective—To understand the important effect of elevated concentration of carbon dioxide on wheat growth.Methods—With the reference to many literatures,the effect of elevated concentration of carbon dioxide on wheat growth was researched from such three aspects as growth,physiology and quality change.Results—The following results are achieved:firstly,the proper increase of CO2 concentration belongs to the fertilization effect,which could improve the growth of grains,increase leaf photosynthesis,reduce respiration and raise wheat yield;secondly,the elevated concentration of CO2 can affect wheat quality;finally,the research emphasis pointed out herein provides the thinking for future research direction.Conclusion—The yield and quality of wheat can be raised by the fertilizer effect of CO2 in combination with previous studies.
