对冷季型草坪草早熟禾进行不同浓度和频次的融雪剂处理,观测草坪草外观质量的变化,研究对草坪草返青率及颜色、质地、均一性和盖度等外观性状的影响。结果表明,试验处理下的盐胁迫对草坪返青率和外观性状都有较大的影响,所有处理的返青率均极显著地低于对照处理;施盐浓度过大延迟草坪草春季返青,施盐次数的增加比施盐总量的增加对草坪返青影响更大;所有处理综合性状评分与对照均有显著差异。

Deicing salt with different concentrations was used to treat cool - season turfgrass, with the aim to observe the change in the appearance quality and research the effects on the appearance characters such as green returning rate, color, texture, homogeneity and cover degree. The results showed that the salt imposed more effect on the rate of returning green and appearance characters, while the rate of returning green of all treated turfgrass was significantly lower than that of the control one. When the concentration of salt is too high, the returning to green period will be de- layed in the spring, and the treatment frequency had greater effects on the turfgrasses than the salt amount did. There were the significant differences in the comprehensive character grading between all treated turfgrasses and the control one.
