生活中我们发现,随着人们物质生活水平的提高,鲜花已逐渐走进了百姓生活。人们走亲访友、探视病人不再像以往那样提着大包小包吃的喝的礼品,而是时尚地送上一束鲜花来表达自己的祝福之意。另外,我们周围还有很多同学的家中,也都用鲜花来点缀居室,这既美化了家居环境,也提高了主人的文化品位。但观察中我们发现,鲜花插在家中花瓶里用不了几天就枯萎凋谢了,能不能想办法使鲜花的“姿色”更长久呢?在老师的指导下我们进行了一些研究。 In life, we discovered that with the improvement of people’s material living standards, flowers have gradually entered the lives of ordinary people. People visit relatives and friends, visit patients, and instead of carrying large and small packages to drink and drink as in the past, they fashionably send a bouquet of flowers to express their wishes. In addition, there are many students around our home, but also use flowers to decorate the living room, which not only beautifies the home environment, but also improves the master’s cultural taste. However, during the observation we found that the flowers in their home vases withered and faded within a few days. Can we think of ways to make flowers look longer? We have conducted some research under the guidance of our teachers.
