Composition on Plant Change in Summer and Autumn 200

An article at the turn of summer and autumn

The alternation of seasons always seems to happen in the rain. A series of heavy rains cleared up the floating dust in summer and dispelled the long-term sultry heat. Autumn has come quietly. In the morning, the breeze is cool; At dusk, the evening breeze is cool. After a long summer vacation, the cool breeze in Xu Lai really makes people feel refreshed and relaxed.

The turn of summer and autumn is the most beautiful time of the year. Flowers are bright and lush. Gorgeous butterflies are still flying among the flowers in the forest. Nature is still full of vitality. Compared with summer, the sky is bluer, the clouds are whiter, the water is clearer, the mountains are stronger and the fields are wider. Shan Ye's pastoral color began to become concentrated and strong. Tian Yun, scenery, flowers and trees all seem to calm down slowly from the passion in midsummer. Silence is the rhythm of autumn. In the evening, we went outdoors and watched the lights, the moonlight on the lotus pond and the quiet forest path bathed in the breeze, which was enough to immerse ourselves in poetry for a long time.

The climate is the most pleasant at the turn of summer and autumn. It is sunny during the day, so people can wear light and short summer clothes. Girls who love beauty can continue to show their beauty. The temperature is suitable at night, which can make people fall asleep beautifully. People fall in love with summer and enjoy the most abundant benefits in both seasons.

At the turn of summer and autumn, melons and fruits are fragrant and the harvest is in sight. The fruit shop in the city is full of all kinds of delicious and attractive fruits. Huge watermelons, red apples, peaches soaked in honey juice, crystal clear grapes, bananas, pineapples and mangoes from the south. Nanguo pear is abundant here. At this time of year, the fragrance of Nanguo pear is floating in the street. We went to the fields and saw endless crops maturing. The cob of corn is golden yellow, the ear of sorghum is red, and the dense ears of rice in the rice field begin to lower their heavy heads. The jubilant farmers are preparing to ring the gongs and drums of harvest.

At the turn of summer and autumn, people face the future with greater confidence. Farmers began to prepare for the autumn harvest; At the beginning of school, the children walked into the classroom with great pride. People from all walks of life began to devote themselves to the biggest harvest this year.

What a good time at the turn of summer and autumn! It brings us comfort, self-confidence and profound life enlightenment.

I wander at the turn of summer and autumn.

Strangely, I remember that in the first half of the year, the media clearly reported that there would be another El Ni? o phenomenon this summer. So I have been preparing for another challenge in the summer of filariasis. In fact, it's not very hot this summer. Of course, I'm talking about the Yangtze River Delta. However, there are some differences.

There is more rain, but it can't improve the steaming of hot air, so there is more hot air. No, it's already the summer solar term, which means the rabbit's tail can't grow in summer. But in fact, the Heat is still alive and there is no sign of retreat. The sun is still raging, happy, and even not tired at all. The weather forecast says that there will be showers and thunderstorms in the future, and the temperature is almost still around 30 degrees Celsius.

There are still signs of autumn. Quiet, quiet, on the roadside, on the shore, in the Woods, willow trees with twisted waist and dancing skirts are flying out of oriole-like leaves, some are golden, some are light yellow, some are yellow-green, and some are light gray-green. Is it a silent invitation? Not much, though. Are they inviting the west wind, which is still far away, or are they keeping the lingering Nanyang? I think they must know about autumn. Because they are more like keys, opening autumn leaves for the second time.

Oh, oh, sure. Autumn came quietly, squinting at the madness of summer before the end, making the crickets in the grass lean on the street corner with a cheerful and depressing attitude, waiting for the clear confession of singing and autumn rain in the name of Gao Chang. However, green areas, roads and water surfaces seem to be eagerly covered with brocade.

In the "cold desert", "small building, silver hooligans are like poor autumn". Every morning, very early, people leave home early and get close to nature. Go for a walk and exercise in the suburbs or parks, scenic spots and green spaces. Let a little cool fresh air embrace you, and of course, wash away the turbid heat and dirty gas in the body, so that the skull can get a little sober. Walking in the cultural atmosphere of the south of the city, such as scenic spots, museums, Duan Yucai Memorial Hall and China Memorial Hall, it seems that the air is filled with faint ink, the autumn wind blows the waves, and the autumn insects sing the evening lotus. Accompanied by all kinds of music played by Tai Ji Chuan, sword dancers and square dancers, I really feel relieved of the summer heat-stepping on the thin morning mist, I feel as if I were in a floating cloud, and I feel naturally happy. "Sing softly:" I walk through the clouds like Bai Lianhua ... ""

I haven't been here for several days. Once, it was lush and depressing.

That time, it was about this time. I walked past the hairy reeds, turned the faint flower stems, crossed the elegant pavilion played by the strings, lightly stepped on a few petals and ran across the wet Duanguan Quqiao. Perhaps the moisture comes from the evaporation of the lake, or it may be the slight dew condensed by the moonlight last night. How thoughtful! And a casual glance, I saw a clear water under the bridge, a beautiful "blue" water-

The water is covered with a large piece of cyanobacteria, like a felt. Color oil. Much like the bright grass buds that just bloomed in early spring-there is attractive blue in green. On this felt, many beautiful curves, narrow or wide, are faintly intertwined, which may be footprints drawn by water waves. Some are flexible, some are euphemistic, some are circuitous, some are straight, some are ups and downs, and some are abrupt jumps. In the crack of the felt curve, the thin lip of the lake is exposed. The felt surface is far and near, patchwork, or one or two or more pieces are decorated with fallen leaves of different colors in groups, like flower patterns, really like colorful carpets, very beautiful! Very beautiful!

However, I can't be happy, just because cyanobacteria are harmful things in water. They usually breed in summer, gather on the water surface under high temperature and strong sunlight, absorb most of the sunlight, and inhibit the growth of other algae while breeding themselves. The proliferation of cyanobacteria continuously secretes toxic metabolites into water, which affects the population succession and reproductive cycle of plankton and can also cause a large number of zooplankton deaths. And a layer of blue-green floating foam is formed on the water surface, giving off a stench, which is called "water bloom". Even some species will produce some toxins, which will aggravate the deterioration of water quality and do great harm to aquatic animals such as fish and people and livestock. In severe cases, the oxygen in the water will be exhausted, leading to suffocation and death of fish. The large-scale outbreak of cyanobacteria is called "green tide" (corresponding to the red tide in the ocean). Green tide causes water quality deterioration, and more seriously, some kinds of cyanobacteria (such as Microcystis) also produce microcystins (MCs). About 50% of the green tide contains a lot of MCs. MCs is not only directly toxic to fish, humans and animals, but also an important cause of liver cancer. It is very dependent on stagnant water. The more lifeless and lifeless the environment, the more moist and bright it will live. Rich nutrition in water makes them: the loss of chemical fertilizer; Domestic sewage; Livestock and poultry breeding, livestock manure contains a lot of nutrient wastes such as nitrogen and phosphorus, which can lead to eutrophication of water bodies; Industrial pollution, including fertilizer plants and wastewater discharge; Burning fossil fuels. These corrupt substances. The little leaves are really starting to rot. It's ... it's really ... it's a beautiful scene that they actually cooperate.

Hey, it turns out that corruption is sometimes so attractive! I just can't get rid of that disgusting stench.

Now it is clear, full of many kinds of fish and full of green trees and flowers. I really like such beauty! People are close to it. I am here. We are all here.

Because of governance! Governance full of positive energy is a beautiful process and has also gained beauty.

I wander at the turn of summer and autumn.
