利用工业尾气进行大棚蔬菜CO_2施肥技术体系研究

Technique system of applying CO_2 from industrial exhaust gas to greenhouse vegetable

对不同气候条件下蔬菜大棚内小气候观测和CO_2施肥试验研究结果进行分析,改进了大棚蔬菜CO_2施肥技术,建立了CO_2施肥经济决策公式和1套从工业尾气中采集CO_2→CO_2产品运输流通→蔬菜大棚内CO_2气肥施放的综合技术体系,为减少工业污染,补偿蔬菜大棚CO_2匮乏,提高大棚蔬菜产量和品质寻求了有效途径。

Based on microclimate observations and the experiments of applying CO2 into the green-houses, an improved CO2 application technique on the amount,time and method was established. An economical decision equation of applying CO2 air fertilizer was also advanced. A technical sys-tem that collects the CO2 from the industrial exhaust gas, transports it by high pressure,and ap-plies it to greenhouse was promoted. It is an effective way to decrease industry pollut,compensate CO2 in greenhouse,increase yield and guality of greenhouse vegetable.
