How does the plant tell us the truth about the state of the environment it finds?

Climatic changes affect the growth of plants, and most plants in the north lose their leaves yellow as the climate cools. There are also flowers that can detect pollution, just after the decoration, there is a certain amount of pollution indoors, causing aloe vera leaves to turn yellow with black spots, if the indoor pot water is large, or the outdoor rain is sufficient, it will cause the flowers to not like to bloom, and sufficient rain will also cause the tree's rings to widen, and the rain-poor ridge of the age of the tree's rings will be narrowed accordingly. There are also potted flowers, if you change to a new environment, some flowers will have an adaptation process.

This is a must-know for some flower lovers who have been cultivating a variety of flowers for many years.

- This is Xiao Luzi's question...

I love the rhododendron, she is the city flower of Shenzhen. I met her on the wide green road in Shenzhen. She was open on the pergola of the flower bed of the city hall, she hung high on the wall of the Youth Palace, she leaned out of the courtyard of the old cadre activity center, and she was waving in the wind on the balcony of the residential building.

Here it was crimson, it was her; There was a purple red, and it was also her; The ground was red, it was her; The air was pink, and it was still her. The pavilions and pavilions are all her sultry style. Decorate a beautiful and pleasant city like a garden to make it more moving.

For example, I love the rhododendron, her vitality is extremely vigorous, easy to plant, easy to raise, and easy to flourish. As long as you cut a tree in a sunny place, you can enjoy the scenery for many years. Moreover, in a southern country like Shenzhen, where the four seasons are like spring, the rhododendron can be opened all year round.

Her continuous prosperity and her unfailing enthusiasm are similar to the image of Shenzhen, the window of reform and opening up, and the city that produces the story of spring. The selection of her as the city flower of Shenzhen is really well deserved.

I love the rhododendron because it's a creeping plant. She can climb up to the wall and dance gracefully; She can also hang high in the air, just like Ziyan in the wind. The vines are neither tall nor short, and the branches and leaves are neither numerous nor sparse, setting off the flourishing safflowers, which are slender and graceful.

She is simply a symphony, a backgammon, a "Spring River Flower Moonlight Night", or "Danube Waltz", flying and fluttering in the air, trembling and echoing in people's hearts.

I love the cuckoo because of her color. Red has always been my favorite, and it goes best with green. And the blood-like red of the rhododendrons made me fall in love with it even more.

The most abundant flowers of the rhododendron are purple and red, representing her nature, which uplifts people, stimulates enthusiasm and exalts optimism. Although there are occasional pinks, and even other colors are specially cultivated, they are not ambitious.

This description of Le Rhododendron can be seen that the author has observed for a long time, he observed the place where the peanut grows, the environment in which the flower lives, and the color of the flower, and then writes down what he sees and feels in the order of his observations, using paragraphs in a comparative manner, which gives the reader a strong infection.

"I look at the trumpet flower".

I planted a trumpet flower in a pot, which is morning glory, and it is growing. Its inner leaf shape is peach-shaped.

It was planted two months ago, and now it has a purple trumpet-shaped flower.

The young shoots of the trumpet flower are pointed and explored in all directions, but the speed is very slow, and it seems that there is no change, as long as it is after a while, and then compare the position, you can find that it is moving. It's so much fun to instinctively wrap around an object that you can wrap around whenever you encounter it.

Through careful observation, I really discovered some of the mysteries of the growth of trumpet flowers, and observing the growth of plants is an unforgettable little thing, and it is also a very interesting thing.

There's nothing here, there's nothing.

Generally, it is compared with the normal state of the same plant, such as petunia growing in a normal environment and petunia in an environment with too much sulfur dioxide content in the air, the latter leaves will have symptoms such as macular spots and deformities; If the soil is deficient in magnesium, the old leaves of the plant will appear yellow spots earlier than the new leaves; Calcium deficiency is the opposite; Potassium deficiency, phosphorus deficiency, and boron deficiency will have different symptoms; The plants born in the cold zone of the alpine are shorter than those of the same plant in the warm zone; Sometimes the shape of the canopy of the trees on the hill can be used to infer the long-term wind direction of the site; Plants that sprout in the dark have slender and thin stems, hooked stems at the tips, and pale yellow leaves (sprouts).

The cactus and epiphyllum leaves in the cactus family are degraded and become fleshy stems, typical xerophytes. Sedum is a perennial succulent herb that blooms in summer and autumn with small, luxuriant flowers of various colors. The epidermis has wax powder, stomata are sunken, which can reduce transpiration, it is a typical xerophytic plant, asexual reproduction is strong, and the so-called leaf picking can be planted and rooted.

Sedum plants are dwarf, and because they are fleshy, they consume little water and fertilizer, so they are easy to plant and ornamental.

Aquatic plants such as water lilies and rice have gaps in the stems, that is, well-developed aeration tissues, and the leaves are generally non-waxy Aquatic plants are divided into upright plants, floating plants and submerged plants, each with its own characteristics.

When the external environmental conditions are not suitable for the growth of the plant, it will have some symptoms, such as yellowing of the leaves, wilting, spots of different colors and sizes on the leaves, and leaf shedding.

I used a plastic bottle, filled it with some soil, planted a few mung beans, watered it, and began to wait for the mung beans to germinate.

A few days later, the hard work finally paid off, and the mung bean successfully sent out a small green seedling with the first round of the void. I almost looked at them, and felt that they were like knights, with sharp knives, struggling hard, all trying to fight over who was the first to drill out, the first to see the wonderful world outside.
