Chinese. 研究了臭氧处理对温室土壤化学性质和甜瓜单瓜质量的影响.结果表明,随着臭氧处理剂量的升高,土壤有机质下降,其中高剂量臭氧处理后10- 15 cm土层有机质含量显著低于对照;各土层氨态氮显著下降,土壤pH值、EC值、硝态氮上升,全氮、全磷、有效磷呈下降趋势,但处理与对照间均未达到显著水平;臭氧处理对土壤全钾、速效钾无明显影响,但可促进大棚甜瓜单果质量增加,其中低剂量处理单瓜质量显著高于对照.[著者文摘]

The effects of ozone treatment on soil chemical properties and single-fruit weight were studied.The results showed that the content of soil organic matter decreased along with the increase of ozone concentration.The content of soil organic matter in 10～15 cm deep was lower than the control after treated with higher concentration of ozone.NH＋4-N reduced remarkably in every layer,soil pH,EC,NO3-N rose,the total N,total P and available P decreased,but not significantly difference were found with the control.No obvious effects were also observed on total K and active K under different treatment of ozone.The single-fruit weight increased and reached remarkably level under the low ozone concentration treatment.
