摘　　要：设施栽培下空气中CO2浓度经常处于亏缺状态,为提高秧苗的光合强度,在同一黄瓜品种上采用3种不同的CO2浓度进行穴盘育苗CO2气肥试验,得出穴盘育苗条件下增施CO2可显著提高秧苗生长量,最适宜的CO2施用浓度是1.200ml/L。CO2 density under facility cultivation always shows deficit. On the purpose to improve intensity of photosynthesis, three densities of CO2 have been applied as gas fertilizer to the same cucumber species and the results show that to increase CO2 application could promote seedling growth in hold seedling nursary and the recommended density is 1.200 ml/L.
