| 摘 要： | 本试验利用中国科学院山西煤化所研制的NC—A型农用CO_2发生器产生CO_2气肥,进行了CO_2施肥对大棚黄瓜生长发育影响的试验。结果表明,CO_2施肥可以改善大棚内的小气候;促进大棚黄瓜植株的生长发育,株高、茎粗、叶数、叶面积、根重、须根数、根长等植物学性状都优于对照;增加了大棚黄瓜的前期产量和经济效益;提高了果实中的维生素C、可溶性糖、可滴定酸的含量以及糖酸比,改善了大棚黄瓜的品质。这些充分说明,CO_2施肥是大棚黄瓜早熟、丰产、优质的很好措施。

| Abstract: | CO_2 was generated by an NC—A type CO_2 generator manufactured by Shanxi Coal Chemistry Institute. The results showed that application of CO_2 could change the microclimate of the plastic film house and improve cucumber growth. The plant height, stem width, leaf number, leaf area, number of total roots, number of secondary roots and root length were all increased, compared to the eontrol. The contents of Vitamin C and soluble sugar, the titratable acidity, the sugar—acid ratio of the cucumber in the treatments with CO_2 fertilization were increased,and the quality was improved. Early yield was increased and greater economical benefit was obtained. All this indicates that CO_2 fertilization is a good practice for cucumber production in plastic film houses. |
