Poetry is a wonderful flower in the garden of ancient Chinese literature. With its brilliant colors, charming appearance, and intoxicating fragrance, it has always attracted the attention of the people of the Yan and Huang Dynasties. Did you know that? There are many descriptions of biological phenomena in poetry. Sentences. Our group found these through collection and sorting, let me take everyone to enjoy them together. "Jasper makes up a tree as high as a tree, and thousands of green silk ribbons hang down." This is a description of the beauty of the willow tree. I heard such a poem , in campus and urban greening, how can we not choose willow trees? "Stop and sit in the maple forest at night, the frost leaves are as red as the February flowers." This is a description of autumn leaves. Everyone knows that the color of leaves mainly depends on chlorophyll. , but there are not only chlorophyll in the leaves, but also some other pigments. Take maple leaves as an example. In autumn, the chlorophyll decomposes and the anthocyanins in the leaves appear, so the leaves turn red. Students all know Bai Juyi’s The song "Remembering the South of the Yangtze River", "When the sun rises, the flowers on the river are as red as fire, and when spring comes, the water on the river is as green as blue." How beautiful. But do you know how these beautiful colors are formed? Let me tell you, hello everyone, in the first half of the sentence Understand, the second half of the sentence refers to our biological phenomena. It is the color of the river due to the proliferation of large amounts of algae. In short, through our investigation, many poems describe biological phenomena.
The poem "April in the world is full of beauty, and the peach blossoms in the mountain temple begin to bloom." This poem describes such a scene. The peach blossoms at the foot of the mountain have already failed, but the peach blossoms on the mountain have just begun to bloom. This shows that flowering is affected by temperature conditions. .In fact, there are also poems describing this biological phenomenon. For example, "The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from the bitter cold", "The swallow grass is like silk, and it grows again when the spring breeze blows." We also found such poems " "Luohong is not a heartless thing, it turns into spring mud to protect flowers", which means that after fallen leaves fall, they dissolve into the soil, are decomposed into inorganic matter by bacteria in the soil, and are reabsorbed by the plant body to provide nutrients for the plant body. Our group is the largest My feeling is that there are many biological phenomena around us. As long as we observe carefully, we will discover the beauty of living things.
