摘 要:探讨了黄瓜植株生长量与温室内CO2浓度之间的关系,研究结果表明:随着生育时间的延长,栽培黄瓜的温室内CO2最高浓度、放风前CO2浓度都呈下降趋势,而温室内CO2浓度的下降速率则不断增大.温室内CO2下降速率与植株叶面积呈显著相关关系.The relationship between cucumber growth increment and CO2 concentration in greenhouse was studied by the application of formulated organic materials mentioned above. With the increase of the cucumber increment both the peak CO2 concentration and CO2 concentration before ventilation had a descending trend. However, the descending speed of CO2 concentration in greenhouse became larger. The results also showed that there was existing the significant correlation between the descending speed of CO2 concentration in greenhouse and the leaf area.
