| 摘 要： | 设施栽培番茄连作障碍严重,影响设施蔬菜生产和发展。本试验采用活性氧技术处理设施连作5年的番茄大棚土壤,种植番茄,考察活性氧技术对设施栽培连作障碍的效果。结果表明：在夏季大棚休闲期,采用活性氧水灌溉处理2次,然后覆盖密封1个月,土壤微生物生态系统发生改变,土壤残留尖孢镰刀菌番茄专化型比对照下降79.2%~93.5%,番茄青枯病菌比对照下降83.3%~91.7%;土壤表层可溶性盐分减少,电导率比对照下降55.5%,容重下降4.43%。种植番茄后,活性氧高温淹水焖棚处理比对照增产20.2%~23.7%,表征番茄品质的Vc、可溶性总糖、膳食纤维分别比对照增加52.9%~76.2%、12.8%~16.8%、20.9%~23.3%,番茄果实残留硝酸根比对照下降16.3%~14.2%。表明活性氧及活性氧高温淹水焖棚可以用于修复设施栽培土壤连作障碍。

| Abstract: | Soil sickness in facility agriculture of tomato cultivation is so severe that could affect greenhouse vegetable and fruits production. The control and inhibition effects of activated oxygen technology (AO) on soil sickness was studied on soil of 5 years successive tomato cultivating. The results showed that soil microbial ecosystem changed after the treatment, the amounts of forma specialis Fusarium oxysporum decreased by 79.2%-93.5%, Ralstonia solanacearum decreased by 83.3%-91.7% compared with CK after irrigated with AO water twice and sealed with plastic film of 1 month. Compared with control, topsoil soluble salts declined and soil conductivity was reduced by 55.5% and bulk soil weight decreased by 4.43%. For tomato cultivation under the AO treatment, the yield increased by 20.2%-23.7% compare with CK. The Vc content, total soluble sugar content and edible fiber in tomato fruits increased by 52.9%-76.2%, 12.8%-16.8%, and 20.9%-23.3%, respectively, while the content of nitrate decreased by 16.3%-14.2% in comparison with the control. In conclusion, activated oxygen and high temperature solar flooding technology could be used to prevent and control soil sickness in facility agriculture. |
