我曾在某报刊上见过这样的报道,南京一个广场引种欧洲的草坪品种,每年的养护费用高达2万多元,原因是南京夏季炎热,气温超过35℃,原产欧洲的草坪草不耐高温,最后只好铲掉;而从热带国家引种的草坪,在南京又过不了冬,因为江苏各地冬季低温可达-7～-8℃,真是无所适从。 I have seen such reports in a newspaper. A square in Nanjing introduced species of European lawn with an annual maintenance cost as high as over 20,000 yuan. The reason is that Nanjing is hot in summer and the temperature is over 35 ℃. The lawn grass of the native Europe is intolerant High temperature, the last had to shovel out; and from the introduction of tropical countries, the lawn in Nanjing and can not win the winter, because the temperature across the winter in Jiangsu up to -7 ~ -8 ℃, really confused.
