大气CO_2与植物氮素营养的关系

The Relationship between Atmospheric CO2 and Plant Nitrogen Nutrition

大气CO2浓度升高对植物吸收氮素,以及对植物和土壤中的氮浓度、C/N比和氮循环都存在着影响。大气CO2浓度与植物氮素营养之间存在着交互作用。大气CO2浓度升高对植物氮素营养影响的结果与氮浓度、氮形态等因素有关。

The elevated atmospheric CO2 has effects on the absorption of nitrogen, concentration in plant and soil, the C/N in plant and soil, the nitrogen cycle of plant and soil. There are interactions between the atmospheric CO2 and the nitrogen .The results are related with the concentration and the form of the nitrogen.
