大棚蔬菜施气肥优质高产效益好二氧化碳简称气肥,是作物进行光合作用的主要原料。据测定,蔬菜进行光合作用最理想的二氧化碳浓度为1000ppm,而空气中的二氧化碳浓度为300ppm,大棚相对密闭,二氧化碳浓度就更低。有试验表明,如果将大棚内二氧化碳的浓度增...
Greenhouse vegetable gas fertilizer high quality and good yield and efficiency Carbon dioxide gas fertilizer, is the main raw material for crop photosynthesis. It is determined that the most ideal photosynthesis of vegetables for carbon dioxide concentration of 1000ppm, while the concentration of carbon dioxide in the air is 300ppm, relatively confined greenhouse, the lower the concentration of carbon dioxide. Some experiments show that if the concentration of carbon dioxide in the greenhouse by ...
