农业温室慎用臭氧

Questionable ozone applications in agricultural greenhouses

平流层臭氧有益,近地面臭氧是重要空气污染物。臭氧是氧化剂,可用于杀菌和消毒。臭氧也污染环境,既危害健康,也危害植物。臭氧造成农作物减产。对于生长期的温室作物,用臭氧对付病虫害的做法不可取。

Ozone is one of the major pollutants at the ground level,though a good gas in the stratosphere.As an oxidant, ozone may act as a sterilant for some applications in high consentrations.It may pollute the environment if handled carelessly.Ozone pollution results in crop losses.In greenhouse during crop growing,ozone is hardly an alternative for controlling microorganisms and pests.
