Through four years of research, the Nanjing Institute of Soil Science researchers found that as a result of the carbon dioxide concentration in the experimental field improved significantly, like gas fertilizer applied to crops. Rice, wheat yields were higher than the control plots of about 10% -14% and 12% -20% carbon dioxide, the growth cycle is short 6-9 days. In the rice will be ripe season, when large tracts of farmland or a lush Jimo manufacturers of carbon dioxide, within experimental plots of rice, wheat, but has yellowed. At the same time, Rice's appearance, taste and other quality also undergone significant changes. Paddy rice rate was significantly lower, chalky rate and chalkiness significantly improved, so that the rice pasting temperature increased significantly. More simply, where the sale of carbon dioxide that looks more white rice, eat up even more sticky colorless, odorless, tasteless gas. Chemical formula CO2. Earth's atmosphere minor component. Mp -56.6 ℃ (5.2 × 105 Pa), density 1.977 g / cm 3, the critical temperature of 31.04 ℃, the critical pressure of 7.285 × 106 Pa, and therefore carbon dioxide sales, easily liquefied carbon dioxide gas, liquid carbon dioxide can be stored in the high-pressure cylinders. When the liquid carbon dioxide is evaporated, will absorb a lot of heat, the temperature rapidly lowered, which in turn causes a portion of the carbon dioxide gas is condensed into a snow-like solid, which solid can absorb heat from the surrounding, directly into a gas (sublimation), and therefore it called dry ice. Levels of atmospheric carbon dioxide is 0.03%; the ocean is 0.014%. They come from: ① organism decay process. ② humans and animals exhale carbon dioxide. ③ burning of coal, oil, natural gas and other. Carbon dioxide manufacturers, carbon dioxide, Qunli Fung Ltd.
