温室大棚内CO2施用控制技术的研究
Study on control technology of CO2 application in greenhouse
摘要
Abstract
In order to obtain a set of reasonable and economical control technology of CO 2 application ,the internal envi‐ronment factor parameters of the greenhouse and which with applying different concentrations of CO 2 were recorded and analyzed ,and the changes of CO2 concentration in greenhouse at different growth stages such as planting ,flower‐ing ,blooming were learned .By controlling the flow of CO2 tank ,we got a simple CO2 fertilization control technology . The test results showed that the daily variation of CO 2 concentration was usually in the form of "U" type ,and which was more intense and could be less than 200 μL・L - 1 in sunny days .In addition ,ventilation could remain CO2 concen‐tration around 270 ~ 330 μL・L - 1 .From early planting to flowering to blooming ,with the photosynthetic capacity of population increases ,the CO2 consumption becames faster ,accordingly ,more CO2 need to be replenished in green‐house .In the condition of natural ventilation ,in the span of 9 m ,length of 10 m ,high ridge of 4.5m partition space , CO2 concentration could maintain at 382.7 μL・L - 1 with CO2 fertilization velocity of 2.5 LPM (liters/min) .And ,CO2 concentration could maintain at 586.8 μL・L - 1 with CO2 fertilization velocity of 5.0 LPM .However ,CO2 concentration was only 303.2 μL・L - 1 without fertilization .关键词
