摘 要：
工业盐是融雪剂的主要成分,然而施用融雪剂后导致的环境问题已经引起了世界各国的关注。采用盆栽试验研究了施用0.1%、0.3%和0.5%浓度工业盐,生态净化剂,以及0.5%工业盐配施生态净化剂后,黑麦草的生长情况和土壤的pH值、电导率和交换性钠离子含量(Na+)。结果表明,随着施用工业盐浓度的提高,黑麦草的株高和生物产量逐渐降低,而施用生态净化剂可缓解工业盐对黑麦草生长的抑制作用。与施用0.5%浓度工业盐相比,0.5%工业盐配施生态净化剂后,黑麦草地上部、根系和总干重分别增加了63.4%、152.2%和73.8%。另外,土壤pH值、电导率和交换性Na+含量均在施用工业盐后升高,且随着工业盐浓度的增加而增加,在配施生态净化剂后则其降低。可见,工业盐配施生态净化剂,可降低工业盐对植株生长的抑制作用,缓解土壤盐碱化,降低施用融雪剂的环境风险。

摘 要：
Industrial salt is the main component of snow-melting agent.However,application of snow-melting agent caused serious environmental problems which attracted scientists's attention.Pot experiments were conducted to study the effects of application of snow-melting agent treatment(0,0.1% and 0.5% industrial salts),ecological purification agent,and combination of 0.5% industrial salt with ecological purification agent on ryegrass growth and some properties of soil(pH value,electrical conductivity,exchangeable Na+ content).The results showed that the height and biomass of ryegrass obviously decreased with the increasing of industrial salt concentration,and the application of ecological purification agent mitigated the inhibitory effects industrial salt on ryegrass.Compared with the 0.5% industrial salt treatment,combination of 0.5% industrial salt with ecological purification agent increased the above-ground biomass,root weight and total biomass of ryegrass by 63.4%,152.2% and 73.8%,respectively.Meanwhile,the soil pH value,electrical conductivity,exchangeable Na+ content increased with the increasing industrial salt concentration,but decreased after the application of ecological purification agent.It could be concluded that the application of ecological purification agent could mitigate the inhibitory effects of industrial salt on plant growth and soil salinization,thus reduce the environmental risk of application of snow-melting agent.
