Effects of CO2 Concentrations on the Growth and Yield of Cotton
不同二氧化碳浓度处理对棉花生长发育和产量形成的影响

Experiments of CO2 concentration at 700ppm,500ppm and natural condition on the effects of cotton growth and development,yield formation were carried out by using OTC-1 open top chamber. The results showed that increasing CO2 concentration especially when CO2 concentration especially when CO2 concentration at double level of the natural condition,the growth and development,biomass production and yield of cotton were all greatly improved.
