1施用CO2气肥的意义CO2是绿色植物光合作用的主要原料,自然界中CO2的浓度一般是320ppm。一般蔬菜作物的CO2饱和点是1000～1600ppm,在饱和点以下,植株光合速率随CO2浓度的增大而提高,由此可看,自然界CO2浓度是不能满足蔬菜作
1 The significance of CO2 fertilizer application CO2 is the main raw material for photosynthesis of green plants, the concentration of CO2 in nature is generally 320ppm. CO2 saturation point of general vegetable crops is 1000 ~ 1600ppm, below the saturation point, plant photosynthesis rate increases with the increase of CO2 concentration, we can see that the natural CO2 concentration can not meet the vegetable
