关于CO_2肥料在生产上的应用,过去国内外的研究多局限于室内,这在很大程度上是因为CO_2是气体,田间不易控制。从1982年开始,我们对CO_2在大田中的应用进行了探索、现将情况初报如下:据测定首先证实:冬小麦的株间CO_2浓度(拔节后),通常情况下稳定在0.012%—0.02%,比大气浓度(0.03%)几乎低一倍左右。显然这是由于小麦的光合作用,同化了一部分CO_2所引起的。而作物进行光合 About the application of CO 2 fertilizer in the production, the research in the past at home and abroad was mostly confined to the interior, which is due in large part to the fact that CO 2 is a gas and not easy to control in the field. Since 1982, we have explored the application of CO_2 in the field. The first report is as follows: According to the determination, it was first confirmed that the inter-strain CO_2 concentration (after the jointing) of winter wheat is stable at 0.012% -0.02% , Almost twice as low as the atmospheric concentration (0.03%). Obviously this is due to the photosynthesis of wheat, assimilated part of the CO 2 caused. The crop photosynthesis
