| 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。

| Abstract: | CO_2 density under facility cultivation always shows deficit.On the purpose to improve intensity of photosynthesis,three densities of CO_2 have been applied as gas fertilizer to the same cucumber species and the results show that to increase CO_2 application could promote seedling growth in hold seedling nursary and the recommended density is 1.200 ml/L. |
