It s the same plant, why do outdoor flowers freeze to death but trees don t?

In real life, many people like to plant some flowers and plants in their daily leisure time to enrich their spare time. For those who love flowers and plants, they will find that in winter, these flowers and plants are likely to die due to the cold. It is very strange that flowers and trees are both plants, so why do flowers freeze to death outdoors, but trees often do not freeze to death outdoors?

This is actually a phenomenon caused by the natural environment in which the trees adapt.

1. Frost resistance In winter, we will always find such a phenomenon, some trees will freeze to death because of the cold in winter, and some trees are still alive even though they are more than 30 degrees below zero. This shows that in nature, different plants have different frost resistance. For example, in the Tohoku region, we will find trees such as pines and cypresses and holly, although the surrounding environment is already dripping into ice, they can still be green and dazzling and withstand the test of winter.

In the north, pear trees survive the cold winters, even though they are in minus 20 to minus 30 conditions.

Second, the reason why trees do not freeze to death is well known, in winter, if we put flowers and plants outside, these flowers and plants are likely to freeze to death because of the cold. Most trees grow outdoors, but in winter, they are less likely to freeze to death because they are used to the outdoors. In other words, the main reason why trees do not freeze to death in winter is that trees are more resistant to frost than flowers and plants.

In winter, trees tend to put themselves to sleep in order to prevent themselves from freezing to death due to the cold environment.

3. OverviewAlthough flowers and trees are both plants, because flowers and trees have different frost resistance, flowers outdoors are likely to freeze to death, while trees are not.

Because the size of the flowers is relatively small, once the weather is too cold, it may even freeze, and the trunk of the uncle is wrapped in a thick layer of bark, which has the effect of protecting against cold and frost.

That's because these are two different plants, frost resistance is not the same, and there is a big difference in the temperature of survival, so they will face the same environment and cause different results.

Personally, I think this situation is very normal, because the trunk of flowers is relatively thin and very fragile, and the trunk of trees is relatively strong, which can well preserve nutrients and water.

In fact, it is because some trees outside will have very thick bark, and these barks will play a role in keeping warm, so it will cause this phenomenon.

Low temperature will reduce or even inactivate the enzyme activity in plant cells, low temperature will also make the free water in the cell and even the bound water freeze, so that the biochemical reaction of the cell can not be carried out, in addition to the increase in the volume of free water frozen in the cell, the cell structure will be destroyed, and the plant will die when the temperature is too low or the temperature is too low and the time is too long.

Plants are one of the main forms of life, including familiar organisms such as trees, shrubs, vines, grasses, ferns, green algae, lichens, etc. It is estimated that about 350,000 species of plants such as seed plants, bryophytes, ferns and ferns are still alive. Most of the energy of green plants is obtained from sunlight by photosynthesis, and temperature, humidity, and light are the basic needs of plants for survival.

Seed plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize:

With the help of light energy and chlorophyll, water, inorganic salts and carbon dioxide are used for photosynthesis in the catalytic operation of enzymes, and oxygen is released to produce organic matter such as glucose for plant use.

Grass flowers include daylily, shoot dry, February orchid, peony, wheat winter, chrysanthemum, cinchona, caryophyllus, hollyhock, okra grandiflora, mint. Tulips, chrysanthemums, red mushrooms.

The flowers and shrubs include peach blossoms, begonias, hibiscus, pomegranates, hibiscus, cherry blossoms, spring greetings, spring exploration, peony flowers, moon flowers, roses, roses, boxwoods, red-leaved barberry, and magnolia.

No spines of the medlar.

Thornless medlar is a natural variety of holly medlar, an evergreen shrub or small tree with lush branches and peculiar leaf shapes, thick green and shiny. The crown is round, 4 May blooms yellow-green small flowers, drupes spherical, the beginning of green into autumn mature turn red, full of branches and fruits, bright and eye-catching, after winter does not wither until the next spring, after pruning and shaping can be made into a large tree, spherical and tree-like bonsai, is a good ornamental tree species for viewing fruit and leaves.

There is pothos at home, don't open the window at night!

Frostbite state: When the temperature is lower than 10, pothos leaves are prone to yellowing and even frostbite. Pothos leaves with mild frostbite will wilt and turn yellow, and pothos leaves with severe frostbite will turn black and wither.

How to treat: Once the pothos is found to be frost damaged, cut off all the branches and leaves that are not in good condition and keep the healthy stems. As long as the roots are not frozen to death, they can germinate again in high temperatures.

How to prevent: Pothos raised by the window, don't open the window at night in winter, and don't let the pothos leaf direct carrier state stick to the glass. When the temperature is low, the pothos is attacked by the cold wind and freezes in minutes. Not discussed.

There is a lot of meat at home, don't go too far!

Frostbite state: In order to color fleshy meat, many meat lovers are still pushing its limits, and as a result, they accidentally freeze into crystal meat. When frozen, the meat becomes transparent, moist, and black.

How to treat: For mild frostbite, move the fleshy meat to 10, the temperature is not too high, but it can be recovered. For severe frostbite, the frostbitten area is excised and carbendazim is applied to the incision.

How to prevent it: Meat lovers in the open air should always be aware of the weather. If the temperature is below 5, it is better to move indoors. If there is a lot of meat, blow the snow off and carry it to the house. You can't wait for it to melt.

There are spider plants at home, and the roots and leaves are afraid of freezing!

Frostbite state: Spider plant will be frostbitten when the temperature is lower than 6, and its roots and leaves are easily frostbitten. The frozen spider plant roots will rot, and the leaves will soften and darken from the freezing, becoming darker in the sun.

How to treat it: If the leaves are frostbitten, cut off their heads, keep the soil moist, and new leaves will grow in the spring. If the roots of the spider plant are frostbitten, the spider plant will be dug up, and the frostbitten roots will be cut off and replanted.

How to prevent it: It is best to keep the room temperature above 12 in winter. If it is below 12, it should be watered less or even cut off. When the potting soil is almost dry, it is better to slip some water when the temperature is high.

There is watercress green at home, and the roots are more afraid of freezing than the leaves!

Frostbite state: When the temperature is below 5, watercress will get frostbitten. With mild frostbite, the stems and leaves will become soft, or the leaves will fall off. Severe frostbite will start at the bottom of the rhizome and turn black and soft.

How to treat: When frostbite is mild, the curing temperature rises, and the watercress green will slow down. In severe frostbite, the non-blackened stems and leaves at the top of the branches should be cut off for cuttings, and all blackened stems and leaves may be hung.

How to prevent: Watercress will stop growing when it is below 10, so it is best to raise it above 10 in winter. If it is below 10, the water should be controlled, and the dry soil temperature is high at noon.
