二氧化碳在农业生产上的应用研究,是植物生理基础理论,用于农业生产的一项很有价值的成果。在作物生长的小气候中,二氧化碳的浓度还不到300PPm,远不能满足作物的需要,因此二氧化碳的亏缺,已成为提高作物产量的限制因子。根据国外大量研究成果表明,适当提高作物群体环境中二氧化碳浓度,既可增加光合作用的原料,又能降低作物(特别是C_3植
The application research of carbon dioxide in agricultural production is a very valuable result for agricultural production which is the basic theory of plant physiology. In the microclimate of crop growth, the concentration of carbon dioxide is less than 300 ppm, which far can not meet the needs of crops. Therefore, the shortage of carbon dioxide has become a limiting factor for increasing crop yield. According to a large number of foreign research results show that the proper increase of carbon dioxide concentration in crop environment can not only increase the photosynthesis of raw materials, but also reduce the crop (especially C_3 planting
