农业有机废弃物发酵CO_2施肥对大棚黄瓜生长及品质的影响

Effect of CO_2 enrichment by fermentation of agricultural organic wastes on cucumber growth and quality in greenhouse

以稻草和有机肥为发酵原料,研究了农业有机废弃物发酵CO2施肥对大棚黄瓜生长、产量和品质的影响。结果表明:有机废弃物发酵CO2施肥使大棚内平均CO2浓度增加了2.6倍,日均温度提高1℃,显著促进黄瓜的营养生长,明显改善了黄瓜品质,提高了黄瓜的结果数,单棚总产提高25.13%,上市时间提早8 d。此外,黄瓜细菌性角斑病染病植株率、叶部病指数较对照低12%和23%。

A field experiment was carried out to study the effects of CO2 enrichment by fermentation of organic wastes（rice straw and organic fertilizer） on the growth,yield and quality of cucumber in greenhouse.The results showed that CO2 enrichment by fermentation could increase average CO2 concentration 2.6 times and raise daily average temperature 1℃,meanwhile,cucumber growth,yield and quality also significantly increased,resulting in 25.13% productivity raised and 8 days ahead of marketing time.Furthermore,the morbidity of angular leaf spot of cucumber and leaf disease index decreased by 12% and 23%,respectively.
