What plants are there in the wind-borne seeds?

What plants are the seeds spread by the wind? Plants have many ways to spread seeds. Different plants also have suitable methods to spread seeds. Wind propagation is the most common one. What plants are the seeds spread by the wind?

What are the plants that spread seeds by the wind? Many kinds of plants spread their seeds through the wind. Here are a few examples. For example, dandelion, willow, Showa grass, poplar, hyacinthus orientalis and so on. These plants are all plants that spread their seeds by the wind.

Dandelion:

Dandelion's white fluff ball is its seed, and the number of seeds is very large. When the wind blows over the seeds, they will be taken away and begin to grow after landing. When cultivating dandelion, artificial wind can be used to control the spread of seeds, so as to achieve the purpose of large-scale growth of dandelion.

Willow:

The seeds of willow are catkins with white fluff on the surface, so they are called "catkins" because they fly like catkins in the wind. Catkin is light and easy to fall off. As soon as the wind passes, it will blow catkins everywhere, thus multiplying seeds.

Showa grass:

Showa grass looks like a ball of cotton. When the wind blows, seeds like cotton will be blown away by the wind and spread to other places. Showa grass has strong vitality, tolerance to yin and yang, and can grow in various environments.

Poplar:

Poplar is a deciduous tree, which grows bigger. Poplar blossoms in early spring, and when the flowers fail, they will bear fruit. There are slender white hairs on the seeds inside the fruit, and the seeds will fly with the wind when they meet the wind. Wherever the seeds are blown by the wind, they will take root and sprout there.

Hyacinthus orientalis:

Hyacinthus orientalis's seeds are relatively light and can be spread far away by the wind. When breeding in hyacinthus orientalis, plants need to be placed in the indoor air outlet to prevent hyacinthus orientalis seeds from being blown indoors by the wind and affecting the human respiratory system.

What plants are the seeds spread by the wind? Thistle, Showa grass, poplar, willow, dandelion and other plants spread their seeds by wind.

1, self-propagating.

The so-called autobiography is spread by plants themselves and does not depend on other media. The fruit or seed itself has weight, and when it matures, it will fall directly to the ground due to gravity, such as persimmons and olives. However, some capsules and pods will produce ejection force when the fruit is ripe and cracked, which will eject the seeds, such as five-core stone. The propagation distance of self-propagating seeds is limited, but some self-propagating seeds will spread twice after landing. Birds, ants and mammals are all possible secondary communicators.

2. Wind propagation.

Some seeds grow appendages shaped like wings or feathers and fly in the wind. Most of the seeds with pinnate appendages are herbs, such as yellow quail in Compositae, and woody plants are willow and kapok. In addition, the ratio of surface area to weight of some tiny seeds is relatively large, so seeds can be scattered with the wind, such as orchids. The achene of Taraxacum mongolicum, a compositae plant, opens its crown like a parachute when it matures, and flies with the wind, spreading its seeds to far places.

3. Water transmission.

Water-borne seeds, whose surface wax is not in contact with water (such as water lilies), have air cells in their skins, whose specific gravity is lower than that of water, and can float on the water surface and spread through streams or ocean currents. The seed coat of such seeds is often rich in fiber, which can prevent the seeds from rotting or sinking due to soaking and water absorption. Coastal plants, such as chessboard feet, lotus leaves and olive seeds, have typical water-borne seeds.

What are the plants whose seeds are spread by the wind? 3. How does dandelion spread? Wind-borne seeds.

Dandelion is a perennial herb in Compositae, but the flower head of dandelion actually belongs to raceme, which means dandelion flower is composed of many small flowers. So how does dandelion spread? It can be seen that dandelion seeds are spread by wind, which is also to prevent the seeds from being too dense. Let's explain in detail how dandelion spreads.

Spreading mode of dandelion seeds

In the mode of dandelion transmission, dandelion is pollinated by insects. When the seeds are fully mature, the seeds are covered with a fluffy mass, which can be spread far away by the wind. The purpose of seeds drifting with the wind is also to avoid seeds being too dense. After the seeds land, as long as the conditions are right, you can see the brand-new dandelion.

Main points of daily maintenance of dandelion

1, soil requirements

The growth of dandelion does not require much soil, so it is most suitable for maintenance with loose and fertile sandy soil, which can be mixed with humus soil, river sandy soil and pastoral soil, or directly maintained with nutrient soil, all of which can ensure the growth of dandelion.

2. Plenty of light

The growth of dandelion needs sufficient light conditions. In the process of reproduction, the plant must be kept in a place with sufficient light, and the plant receives enough scattered light, which is more conducive to its growth and flowering. The light is strong in summer, so corresponding shading measures should be taken in summer to avoid the damage of direct strong light to plants.

3, fertilizer and water requirements

Breeding dandelion requires reasonable watering and fertilization. The key point of dandelion watering is that it gets wet when it is dry. Water according to the dry humidity of the soil to keep the soil moist, but there can be no water accumulation. The key point of dandelion fertilization is to apply more dilute fertilizer, choose dilute liquid fertilizer for spraying, apply fertilizer once every half month in the growing season, and topdressing phosphorus and potassium fertilizer in time before and after flowering.

4, pest control

Dandelion breeding should also do well in pest control, and in the process of daily maintenance, the ventilation conditions must be strengthened, especially in summer. In summer, carbendazim solution should be sprayed once a week for a month. Once plant diseases and insect pests occur, it is necessary to cooperate with the corresponding drugs to do a good job of prevention and control.

How does dandelion spread its seeds through the wind?

Dandelion is a perennial herb of Compositae, which is a kind of plant with high ornamental value and complete efficacy. There are many flower friends who raise dandelions. So how does dandelion spread seeds? Dandelion flowers are made up of many small flowers. Under normal circumstances, dandelion spreads seeds through the wind, which can also place seeds too closely.

Method for spread dandelion seeds

How does dandelion spread seeds? Dandelion spreads its seeds through the wind. Dandelion flowers, when mature, float in the wind like parachutes, keeping seeds away. We can also collect dandelion seeds artificially. In general, dandelion seeds can mature in June every year and can be harvested after the seeds become dark.

Key points of planting dandelion

1, planting time

Dandelion collects seeds every summer, and the survival rate of seeds born that year is the highest, so the best time to plant dandelion is autumn every year, when the germination rate of seeds planted is the highest. Of course, we can also store dandelion seeds and plant them next year.

2. Germination accelerating treatment

In order to ensure the success of planting, we need to do a good job of accelerating germination when planting dandelion. Soak dandelion seeds in warm water for a day, then take them out and put them on a wet towel. Observe the condition of the seeds, and then plant them when they are broken.

3. Soil preparation

Dandelion seed soil is very important. To prepare suitable soil for maintenance, we can directly use nutrient soil for maintenance, or use humus soil, river sand soil and pastoral soil for mixed maintenance, which can ensure the growth of dandelion.

4. Maintenance after planting

After planting dandelion, we must strengthen plant management, control light and water in the early stage to ensure the growth of seedlings. After the seedlings grow, the light conditions can be appropriately increased. Note that fertilization is not allowed at this stage. It takes more than 40 days for the seeds to fully adapt before applying some dilute liquid fertilizer.
