What plants are prepared for winter? What other ways do plants survive the winter?

What plants are preparing for winter, in fact, many plants are preparing for winter.

1. Keep seeds for winter.

Plants overwintering in the way of leaving seeds for winter, rhizomes and leaves will leave seeds in the soil before the arrival of winter, waiting for the next spring to germinate and grow, such as lotus roots and leeks, etc., when cultivating rhizome and leaf plants, they need to collect and dry their seeds and store them in a dry and ventilated place.

2. Falling leaves for winter.

Some shrubs, trees and herbaceous plants will produce hiberin in the body when autumn comes, enhance the ability to resist cold, and make themselves survive the winter, and will also produce delaminated cells in the lower tissues of the petiole, so that the yellow leaves can quickly detach from the trunk, so as not to consume excess nutrients.

3. Wax membrane wintering.

For example, pine and cypress trees will secrete a layer of wax on the surface of the trunk to prevent their excess water from evaporating, and they can also keep themselves warm to avoid frostbite, and plants such as apricot and locust trees will also secrete a layer of gum on the trunk and branches and leaves to protect against cold and frost.

4. Roots for winter.

Some plants will absorb a large amount of nutrients in autumn, and then convert nutrients into sugar through the action of saccharification enzymes in the body, increase the concentration of plant cell fluid in the body, and enhance their cold resistance.

Animals have their own way of spending the winter, so how do trees survive the winter?

Leave buds for winter: poplar and willow seeds for winter: sunflower, soybean roots for winter:

Dahlia and sweet potato seedlings for winter: wheat seedlings and spinach plants have their own special abilities to protect against cold and frost. Evergreen trees are taken"Armor-piercing and helmeting"The method of snow and cold resistance.

For example, pine and cypress trees secrete a layer of wax on the surface of their bark and leaves, which can both keep out the cold and prevent themselves.

Thicken the fur or feathers on your body. Storing food Let the eggs survive the winter, and evergreen trees adopt the method of "armor-piercing and helmet-wearing" to survive the winter. For example, pine and cypress trees secrete a layer of wax on their bark and leaves, which protects them from cold and the evaporation of their own water.

On the one hand, deciduous trees quickly produce "hibernatin" to inhibit growth, and produce delaminated cells in the lower tissues, so that the leaves fall off quickly to reduce nutrient consumption.

Expansion: 1. Introduction:

Plants are one of the main forms of life, including familiar organisms such as trees, shrubs, vines, grasses, ferns, and green algae lichens. It is estimated that about 350,000 species of seed plants, bryophytes, ferns and ferns exist. Until 2004, 287,655 of them had been identified, with 258,650 species of flowering plants and 15,000 species of bryophytes.

Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity and light are the basic needs of plants for survival.

2. Main features.

Plants are a large group of organisms. Plants can be divided into spore plants and seed plants. There is generally chlorophyll, matrix, nucleus, and no nervous system.

There are more than 300,000 species of algae, lichens, mosses, ferns and seed plants, which are further divided into gymnosperms and angiosperms. Plants are multicellular eukaryotic organisms that are capable of photosynthesis. But many cellular algae are also organisms capable of photosynthesis, and the most important difference between them and plants is aquatic and terrestrial.

We can define it like this; Plants are multicellular eukaryotic organisms suitable for terrestrial life that carry out photosynthesis, composed of roots, stems, and leaves, with cuticular membranes, stomata, conductive tissues, and male and female gametocysts, and embryos develop in gametocysts. These important differences indicate that plants are very different from algae, which is why algae are included in the protist kingdom in the Five Realms system. But on the other hand, algae and plants have a lot in common, and whether they are the same species is still debated.

In the eyes of many flower friends, the hot summer and the cold winter are more difficult for plants, and you can also pay attention to the way of shading in summer to improve, and if there is no heating at home in the cold winter, then the wintering problem of plants will be very important. How exactly should plants survive the winter?

Some potted flowers that are sensitive to cold can be placed in a larger pot, between the two pots and on the surface of the pot put some sawdust, chaff, perlite, charcoal and other thermal insulation materials, and then cover with plastic film or glass cover, the thermal insulation effect is also very good.

Build a simple greenhouse on the balcony and put more cold-resistant flowers and trees, such as camellia, rhododendron, smile, etc., which is good for growth and flowering in the coming year. For some stump bonsai and shallow pots and small potted bonsai that like warmth and cold are susceptible to frost damage in winter, different cold-proof measures should be taken according to their different cold tolerance after entering winter. For cold-tolerant plum blossoms, elms, ginkgo, five-needle pine, finch plum, pomegranate, etc., they can be placed outdoors, but also pay attention to frost protection and frost crack damage, and potassium fertilizer can be appropriately increased to increase cold resistance.

For the more cold-tolerant June snow, Nantian bamboo, podocarpus, etc., it should be moved indoors, but the indoor does not need to be heated.

For non-cold-tolerant nine-mile incense, palm bamboo, banyan tree, phoenix bamboo, Luohan bamboo, etc., it should be placed in a heated room, and for those bonsai planted in shallow pots and small pots and bonsai with poor growth, they should also be placed indoors and properly heated. Most foliage plants like high and medium temperatures, and they cannot tolerate low temperatures, otherwise they will cause frost damage and even death. Therefore, foliage plants should take certain measures to protect themselves from cold and keep warm during wintering.

Different foliage plants have different requirements for overwintering temperature. Those that can withstand temperatures below 5 and above 2 are: one-leaf orchid, palm bamboo, cycad, bamboo, rubber tree, spider plant, araucaria (details), etc.; The ability to withstand temperatures above 5 and below 10 are:

Coleus vulgaris, aloe vera, banana, star anise golden plate, monstera, etc.; The temperature needs to be above 10: pothos, Guangdong evergreen, philosopher, variegated wood, pineapple, etc.

The buds of the trees, high above the ground for the winter. The buds of all kinds of grass have their own way of wintering.

If you want to plant a potted plant, you can move it to the house.

1. Leaf loss: In winter, it is more common for bare plants to stand there, because the temperature drops and changes in their bodies, which leads to the beginning of leaf loss. When the weather gets colder and the daylight hours are shorter, it begins to transfer nutrients from the leaves to the branches;

Causes the leaves to begin to wither and the plant to enter a dormant period. In winter, plants "take out" the nutrients they have stored before, and under the action of enzymes, break down these nutrients, with the aim of increasing the concentration of plant cell fluid, so that it will not be easily frozen.

2. Regulate the water in the body: Physiological changes occur all the time in the body of plants. In winter, plants reduce energy consumption and increase their ability to withstand cold. For example, conifers can survive at minus 40 degrees Celsius, which shows its strong ability to survive.

Many plants wither outdoors in winter, but don't make the mistake of thinking that plants are dead, this is their way of protecting themselves from frostbite in the winter. The wilting of plants is a manifestation of reduced water absorption, reducing the amount of water in the body.

Still worried about how to give flowers winter? Take a few minutes to find out.

How to safely enter the autumn and winter of flowers and plants, remember these points to ensure that the plants are not frozen and damaged.

Many ways to survive the winter, the most important thing is that you have to give him a measure to keep warm, you can put it in a warm house, etc.

The ways of plant wintering include leaving seeds for winter, deciduous wintering, wax film wintering, root wintering, seedling wintering, etc., among which the plants that stay for the winter will leave seeds in the soil, and the deciduous plants will shed their leaves to avoid consuming excess nutrients, while the plants with waxy film for the winter will secrete a layer of wax on the trunk to keep themselves warm and moisturized.

1. Keep seeds for winter.

Plants overwintering in the way of leaving seeds for winter, rhizomes and leaves will leave seeds in the soil before the arrival of winter, waiting for the next spring to germinate and grow, such as lotus roots and leeks, etc., when cultivating rhizome and leaf plants, they need to collect and dry their seeds and store them in a dry and ventilated place.
