摘　　要：国内外研究与实践证明,设施栽培中施用CO2气肥对作物具有改善生理功能,促进早熟,提高产量和抗病能力,改善品质等综合效应,是实现园艺作物高产优质的重要技术措施之一。对CO2气肥的综合调控措施有:确定CO2气肥的施用时间、时期和施用浓度,掌握CO2气肥施用的具体方法和应当注意的问题。It has been proved by study and practice at home and abroad, of applying gas CO2 can include following synthetical effects by facility planting, improving physiological functions,accelerating precocity , enhancing yield and disease-resistant ability, improving quality and so on. By the method, it is one of important measures to realize high yield and high quality of garden crops. The synthetical controlling measures to applying gas fertilizer CO2 conclude following aspects, that is, determine accurate time, period and its concentration to apply CO2, and grasp concrete ways and problems to applying CO2, which should be paid attention to
