摘  要:
通过汽雾栽培方式对马铃薯根际连续 35d的CO2 处理表明 :温室大气处理 (CO2 380~ 92 0 μL·L-1+O2 2 1% )和室外大气处理 (CO2 380 μL·L-1+O2 2 1% )马铃薯植株的形态特征非常接近 ,其株高、叶面积、根系质量、匍匐茎数量、块茎产量以及生物量均比根际高CO2 处理 (CO2 36 0 0 μL·L-1+O2 2 1% )明显提高 ,叶片的气孔导度和胞间CO2 浓度增加 ,光呼吸速率与CO2 补偿点降低 ,叶片光系统Ⅱ功能改善 ,光合速率提高 ,植株生长发育旺盛 ,块茎产量增加 ,说明合适的根际CO2 浓度 (CO2 380~ 92 0 μL·L-1+O22 1% )可能是汽雾栽培马铃薯植株生长旺盛的重要原因

摘  要:
The root systems of potato plants(Solanum tuberosum L.)‘Favorita’treated with different CO 2 concentrations by areoponics culture for 35 days showed an increase in plant height,leaf area,root mass, stole number,tuber mass and overall plant fresh mass for the greenhouse gas treatment(CO 2 380-920 μL·L -1+O 2 21%)and outdoor air treatment(CO 2 380 μL·L -1+O 2 21%),compared with a high CO 2 concentration treatment(CO 2 3600 μL·L -1+O 2 21%).In addition,there was an increase in stomatal conductance(Gs)of leaf,intercellular CO 2 concentration(Ci),net photosynthetic rate(Pn)and photochemical efficiency(Fv/Fm)of leaf,at same time there was an decrease in CO 2 compensation point(Γ),photo respiratory rate(Rp)and carboxylation efficicency(CE)for the formers.The results indicated that the appropriate CO 2 concentration(CO 2 380-920 μL·L -1+O 2 21%)in the root zone may be an important reason why the areoponics culture may advance the growth and the development of potato plant.
