通过补充玻璃温室与塑料大棚中二氧化碳的含量，可以增强作物的光合作用，提高产量，这已被大量试验证明。但以前由于增施补充二氧化碳气肥的方法不便于生产操作，大大影响了二氧化碳气肥的运用和推广。科研人员通过几年的研究，发明了颗粒二氧化碳气肥，基本上解决了上述问题?
By supplementing the content of carbon dioxide in glasshouses and plastic sheds, photosynthesis of crops can be enhanced and the yield increased, which has been proved by a large number of experiments. But in the past, the method of supplementing and supplementing carbon dioxide gas fertilizer did not facilitate the operation of production and greatly affected the application and promotion of carbon dioxide gas fertilizer. Researchers through years of research, invented the particulate carbon dioxide gas fertilizer, basically solved the above problems?
