以草莓和土壤为试验材料和研究对象,采用1.0mg·L-1的臭氧水对土壤进行浇灌处理,通过测定土壤矿质元素含量、有机质含量和pH及草莓幼苗根系活力、叶片叶绿素含量和抗氧化酶活性等指标,研究了臭氧水浇灌对土壤营养成分及草莓幼苗生理特性的影响,以期为提高草莓产量和品质提供技术参考。结果表明:臭氧水浇灌可显著增加土壤中大量元素N和P及微量元素Zn的含量,显著增加草莓幼苗根系活力和叶片抗氧化酶活性,提高了草莓幼苗的抗逆性,对土壤pH及草莓幼苗叶片叶绿素含量影响较小,但使土壤有机质含量显著降低。
Strawberry and soil were used as experimental materials and subjects. Water was treated with 1.0 mg · L-1 ozone water. Soil mineral elements content, organic matter content and pH, root activity of strawberry seedlings, chlorophyll content and antioxidation Enzyme activity and other indicators to study the impact of irrigation of ozone water on soil nutrient components and physiological characteristics of strawberry seedlings in order to provide technical reference for improving strawberry yield and quality. The results showed that the irrigation of ozone water could significantly increase the contents of N, P and Zn in soil, significantly increase the root vigor and antioxidant enzyme activities of strawberry seedlings, increased the stress resistance of strawberry seedlings, The content of chlorophyll in seedling leaves had little effect, but the soil organic matter content decreased significantly.
