已有论文阐明,空气中的 CO_2浓度对作物干物质的生成的作用,随着一些内因和外因(即基因型,氮营养,O_2浓度)的不同而不同。这次研究的是 CO_2浓度和光强度以及温度之间的相互作用。我们用四种夏季作物,进行 CO_2加浓、光和温度条件联系在一起的综合实验来阐明 C_3型作物和 C_4型作物的不同感应性能。
It has been clarified that the effect of CO 2 concentration in air on crop dry matter production varies with some internal and external factors (ie genotype, nitrogen nutrition, O 2 concentration). This study investigates the interaction between CO 2 concentration and light intensity and temperature. We used four kinds of summer crops, CO2 enrichment, light and temperature conditions linked to a comprehensive experiment to clarify the C_3-type crops and C_4-type crops of different induction properties.
