摘　　要：大棚蔬菜施用ＣＯ２颗粒气肥，缓解了ＣＯ２亏缺的矛盾，提高了光合生产率，从而表现出高产、优质、高效的综合农艺效应。几年来，产品在山东、河北、辽宁、吉林、河南等省试验，取得了很好的重现性，平均增产幅度３０％左右，投肥效益之比为１∶１０以上，比国内外同类技术产品总成本降低３０％～７０％。The application of granular CO 2 fertilizer on vegetables in sheds mitigates the contradiction of CO 2 deficiency,raises the photosynthesis productivity,and thus shows the comprehensive agronomic results of high yield,superior quality and high efficiency.In the past few years the product has been under experiment in Shandong,Hebei,Liaoning,Jilin,Henan and other provinces,and very good reproducibility has been obtained,with yield increase of about 30% on the average,the ratio of fertilizer applied to benefit at 1∶over 10,and the total cost reduced by 30%～70% as compared to that of the same technical product at home and abroad.
