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

Effects of CO2 Concentrations on the Growth and Yield of Cotton

借助于OTC—1型开顶式气室进行了700ppm、500ppm和自然条件下二氧化碳浓度对棉花影响的模拟诊断试验,结果表明:二氧化碳浓度升高,特别是二氧化碳浓度倍增对棉花生育进程、生物量和产量等均有明显的正效应。

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 re-suits showed that increasing 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.
