Does the cherry tree lose its leaves in winter?
1. Cherry trees shed their leaves in winter. Because defoliation is a normal response of plants to resist the cold, there is no need to worry too much, and the speed and amount of fallen leaves are very large. In addition, the fallen leaves of cherry trees are generally caused by adverse environment, such as continuous high temperature and drought, overcast and rain, etc., or trees infected with brown spot and anthracnose can also cause leaves to fall off.
2. Therefore, it is normal for cherries to lose their leaves in winter, because they belong to deciduous trees. They will lose their leaves in winter. They are very normal physiological activities. It is not normal not to lose their leaves. Cherry winter cherry trees to winter cherry leaves are still oval in shape, about 7-12cm in length, the original leaves are green, but in winter will become withered and yellow, the apex is a little pointed, the edge is serrated.
3. The leaves will fall. Defoliation is a normal reaction of plants to resist the cold in winter. Cherry trees will fall leaves dormant in winter, and it has strong cold tolerance. As long as the winter maintenance temperature is not lower than 10 degrees below zero, it does not need to be moved back to indoor maintenance.
4. Cherry trees shed their leaves from September to December. According to the inquiry network of flowers and trees, cherry trees fall their leaves from September to December, and the time of falling leaves varies in different regions. The leaves fall earlier in cold areas in the north, and later in slightly warmer areas. Cherry trees will be deciduous in winter, are deciduous seedlings, cold-resistant in winter, do not have to worry about frostbite.
5. The loss of leaves of cherry trees in winter may be caused by diseases and insect pests, lack of water, lack of cold protection measures, and so on. Immediate measures need to be taken to help it survive the winter safely.
Why do the leaves bend?
Viral diseases can generally be transmitted by aphids, whitefly and so on. When there is a virus disease in the plant, all or part of the leaves will curl upward from top to bottom, and the leaves will fade, become smaller, wrinkle, clump and so on. In serious cases, there are only veins but no mesophyll, mostly on the heart leaves and upper leaves.
Plant leaves curl, this situation is mainly one-time application of fertilizer in winter, or flower nutrient solution is too thick, resulting in root burning; because the plant can not be absorbed, branches and leaves will wilt. In winter, most plants grow slowly and have little demand for fertilizer and water.
If the soil is too dry in the early stage and the amount of watering is too large in the later stage, the transpiration of crop leaves will be seriously restrained. When the leaves show a state of self-protection, they will roll back and wilt downwards. When the low temperature freezing injury affects the temperature below 10 ℃, the mesophyll cells of crops will be damaged by cold, and the leaves will begin to wilt. In severe cases, the leaves will dry up and bend downward, and the mesophyll cells will become ice and albino.
The irontree is a kind of light-loving plant. If it is placed in a position where there is no light for a long time in culture, the lack of sunlight for its growth will lead to the bending and deformation of leaves. In addition, if the light is too strong, it will burn the leaves and cause bending and deformation. Solution: if you want to make the leaves of the iron tree straight, you should first keep enough light, which can benefit photosynthesis and let the branches and leaves grow luxuriantly.
Specific reason: this is one of the most likely reasons. There is a disease called rust. It belongs to a fungal disease. It can mainly harm the leaves. When you first get sick, the leaves show yellowish-brown spots, which then protrude and darken. If the plant suffers from this disease, not only the above symptoms will appear, but also the leaves are likely to curl.
The method of removing leaves
The best way to clean up fallen leaves is to choose windless and humid weather, which is conducive to the collection of fallen leaves and reduce the production of dust. The leaves in the channel want to clean up and pull into a pile quickly and effortlessly. You can rake and rake the fallen leaves quickly and easily. It can greatly improve the work efficiency. Put a rake into a pile of fallen leaves into a plastic bag, press it into a small volume, and then pack some more.
The time of cleaning leaves the time of cleaning leaves is in the morning, so that the leaves have sufficient drying time before nightfall, so that the leaves will not be in a humid environment due to lack of sunshine and lower temperature at night. The way of cleaning the blade the water spraying method uses the water impact force of the sprayer to wash away the dust on the blade. Generally speaking, the method of spraying water directly can only wash away the dust that has fallen on the plant.
The way to clean up leaves is to spray green plants with tender leaves, such as money trees and green baskets, or new buds of green plants that have just grown, if there is a lot of dust falling on it, it can be removed by sprinkler method, because the dust on the leaves is more appropriate to solve, as long as it is sprayed through a kettle, the floating ash on the leaves can be washed away by the current impact of the sprayer.
Gardenia and so on. If the leaves are dirty, you can add water to the spray can, then drop one or two drops of vinegar and spray them directly on the leaves. Method 5: use a brush to clean the fluff on the leaves of many plants, such as some succulent plants. If you wash it directly with water, the fluff will be removed, so Huahua suggests you brush it gently with a brush, which can not only remove dust, but also clean the leaves.
Spray cleaning: the use of sprayer produced by the flow of impact, effectively remove dust from the blade, this method is simple and easy. Wet cloth wipe: dip in the appropriate amount of water sponge or cotton cloth, gently wipe the leaves, remove dust and sludge, this method is suitable for most indoor plants.
Who is the only child star admitted to Tsinghua University?
Instead, he chose to study hard, and finally, with a good score of 633 in the college entrance examination, he was successfully admitted to Tsinghua University. He was also the only child star in the entertainment circle who was admitted to Tsinghua University, and was the proper campus beauty of Tsinghua University. After graduating from Tsinghua University, Ye chose to go on to graduate school, which is also a proper high achiever. I believe that many students, like Ye, are yearning for Tsinghua University and want to apply for this university in the future.
The only young child star admitted to Tsinghua University has outstanding talent and enviable talent. In fact, there are a lot of big stars who study well, such as Gulinazar and Zhao Jinmai are all big stars who did very well in the college entrance examination. But it is not clear whether you still remember Leaf, a starlet who has starred in TV series such as "my Child, my Home" and "Mother's Heart after Spring".
Sister Lin Chi-ling in Taiwan is a double-degree high achiever from a famous college, but today we are going to talk about an artist who made her debut as a child star. her name is Ye. Compared with Yang Zi, Zhang Yishan and Guan Xiaotong, Ye is not very famous. She has participated in movies and TV dramas such as "back to Lhasa". Although she is not very famous, she is also a beautiful and lovely little girl.
For example, Zhao Liying, Huang Xiaoming, Zhang Yishan, Yang Mi and others. The leaf we want to talk about has always depended on our own efforts, and now it is the only "child star" who has been admitted to Tsinghua University. The child star who became famous when she was young and gave up the entertainment industry is different. she became popular at the age of 7 and 11, which is not the point. The point is that she is the only child star in the entertainment industry who has been admitted to Tsinghua University. Her hard-working attitude and achievements are enviable.
... Formed by water vapor in the air; Ye Ziqing can be seen through dewdrops
Netizens' opinion: the water vapor in the air touches the leaf surface and liquefies into dewdrops netizens' views: the netizens' opinions formed by the accumulation of fog: the wind is small, the sky is clear and less cloudy, and the ground heat dissipates quickly in early spring or late autumn night, due to the decrease of air temperature, the moisture in the air reaches supersaturated, and at this time the water vapor meets the tip of the leaves and realizes the condensation of water. To form dew.
The water vapor in the air comes into contact with the first cooled stone or tree and condenses into small droplets of water, which is dew. In the morning, the weather is still very cold, and the dew will stay on the grass or stones. For plants, the grass and roots absorb a lot of water, which is emitted through the leaves. Because of the high temperature during the day, the water emitted by the leaves evaporates immediately, so it cannot be seen.
The change of physical state of how dewdrop is formed is explained as follows: the formation of dewdrop is a liquefaction phenomenon. In the warm season, the air is relatively humid, and when the temperature decreases gradually, the water vapor in the air does not liquefy into small water droplets and falls on the plants, forming dew drops.
Because the temperature of water vapor in the air decreases to form small water droplets, small water droplets stick on the grass to form dew drops. There are two ways to realize liquefaction, one is to reduce the temperature, and the other is to compress the volume. The critical temperature is the highest temperature at which a gas can be liquefied.
