在温室内施用二氧化碳肥是设施栽培中的一项重要的管理措施,该技术始于瑞典、丹麦以及荷兰等国家。我国虽然起步比较晚,但随着近年来设施农业在我国的大力推广,二氧化碳施肥技术也已被广泛利用,增产效果十分显著。特别是在冬季,由于大棚薄膜经常处于密闭状态,使棚内的二氧化碳得不到外界大气的及时补偿,棚内蔬菜处 The application of carbon dioxide fertilizers in greenhouses is an important management measure in plant cultivation, starting with countries such as Sweden, Denmark and the Netherlands. Although our country started relatively late, with the promotion of facility agriculture in our country in recent years, the technology of carbon dioxide fertilization has also been widely used, and the stimulation effect is very significant. Especially in winter, because the greenhouse film is often in airtight state, so that the shed of carbon dioxide can not be timely compensation for the outside world, greenhouse shed
