| 摘 要： | 【目的】研究净化后废气作为CO2气肥对温室黄瓜植株、果实的生长性状及产量、果实品质的影响，旨在为工业废气的农业资源化利用提供实验依据。【方法】自2011-03-28开始，用自制气肥发生器净化小型民用锅炉产生废气，将废气转化为不同浓度（400（CK）,900,1 200,1 500 μmol/mol）CO2气肥并通施于温室黄瓜，气肥通施持续2个月，测定不同浓度CO2气肥处理黄瓜的株高、茎粗、瓜条长度、瓜粗、产量及果实品质。【结果】 随着通气时间的延长，各CO2气肥处理和CK黄瓜的株高、茎粗、瓜条长度、瓜粗均呈显著增大趋势，其中1 500 μmol/mol CO2气肥处理的各项生长指标均明显高于其他处理。与CK相比，900,1 200,1 500 μmol/mol CO2气肥处理黄瓜的总产量分别提高了12.1%，15.0%，19.7%。随着CO2气肥浓度的增加，黄瓜果实中的Vc和可溶性糖含量逐渐增大，硝酸盐含量明显降低，其中1 500 μmol/mol CO2气肥处理的Vc和可溶性糖含量最高，硝酸盐含量最低。【结论】 通施CO2气肥可促进温室黄瓜植株和果实的生长，提高黄瓜果实的产量和品质。CO2气肥的最佳施用浓度为1 500 μmol/mol。

| Abstract: | 【Objective】The research of this experiment was to study the effects of CO2 enrichment on greenhouse cucumbers in terms of plant growth characters,production and internal quality of cucumber fruits,and to provide basis for the agricultural utilization of industrial waste gas.【Method】Waste gas from mini type civil boiler was purified in a self-built CO2 fertilizer generator and converted into CO2 gas fertilizer.Since 2011-03-28,the gas fertilizer was applied on greenhouse cucumbers by different concentrations(400(CK),900,1 200,1 500 μmol/mol)for 2 months.Measurements of the cucumbers were conducted in terms of plant height,stem diameter,fruit length,fruit diameter,production and fruit qualities.【Result】As the CO2 enrichment prolonged,the plant height,stem diameter,fruit length,fruit diameter of CK and all CO2 fertilized groups showed an upward trend,among which all the indicators in the 1 500 μmol/mol CO2 fertilized group were the highest.Compared with CK the total production of cucumbers in 900,1 200,1 500 μmol/mol CO2 fertilized groups increased by 12.1%,15.0%,19.7%,respectively.As the concentrations of CO2 fertilizer increased,the Vc and soluble sugar content in cucumber fruits increased as well,while the nitrate content decreased,among which the 1 500 μmol/mol CO2 fertilized group was the highest in Vc and soluble sugar content,and the lowest in nitrate content.【Conclusion】Application of CO2 fertilizer on greenhouse cucumbers can boost their plant and fruit growth,and can enhance the fruit production as well as improve the fruit quality.As the research indicates,the best concentration for CO2 enrichment is 1 500 μmol/mol. |
