What are underwater plants,

emergent aquatic plant

Emergent plants are tall and colorful, and most of them have stems and leaves. Erect, the lower part or base is submerged in water, the roots or stems plunge into the mud to grow and develop, and the upper plants are exposed to the water. There are many kinds of emergent plants, such as lotus, calamus, litchi vine, calamus, cattail, Sagittarius and so on.

Floating leaf aquatic plants

Floating-leaf aquatic plants have developed roots and flowers.

Large, brightly colored, without obvious aboveground stems or slender stems that cannot stand upright, but they are usually stored in the body.

This gas makes leaves or plants float on the water. Common ones are Wang Lian, water lily, peach blossom, Euryale ferox, shepherd's purse and so on.

natant hydrophyte

There are fewer species of floating aquatic plants.

The roots of plants are not born in the mud, but float on the water surface, drifting around with the current and wind and waves, and most of them are mainly foliage, providing decoration and shade for the pool water. And because they can not only absorb minerals in the water, but also block the sunlight in the water and inhibit the growth of algae. Floating plants grow fast and can provide covering decoration on the water surface more quickly. However, some species, such as water hyacinth, grow and reproduce very fast and may become pests in water. So you need to catch some with a net regularly. Otherwise, they will cover the whole water surface. In addition, don't introduce this plant into the big pond, because it will be very difficult to remove this plant from the big pond.

Four submerged plants

The roots of submerged plants are born in silt, and the whole plant sinks into the water, and the ventilation tissue is particularly developed, which is conducive to gas exchange in an environment where air in water is extremely scarce. Most of the leaves are long, narrow or filiform, and all parts of the plant can absorb nutrients in the water and grow normally under the condition of low light underwater. There are certain requirements for water quality, because water quality will affect its use of weak light. Flowers are small and short-lived, and are mainly used for leaf viewing. They can produce oxygen during the day, which is beneficial to balance the chemical composition in water and promote the growth of fish.

Aquatic plants, such as plants, grow near the pool and can grow into the mud near the pool from a depth of 23cm. There are many kinds of waterfront plants, which mainly play an ornamental role. Aquatic plants planted next to small wildlife pools can provide hiding places for waterfowl and other animals that patronize the pools. Waterfront plants growing in natural conditions may spread in pieces. However, after transplanting to a small pond, it is no problem to control root spread with a cultivation pot as long as it is pruned frequently. Some prefabricated pools have shallow water areas, which are specially prepared for waterside plants. Of course, plants can also be planted in flat-bottomed cultivation pots and placed directly in shallow water.

hygrophilous plant

This plant grows in wet soil near ponds or streams, but its roots cannot be submerged in water. Hydrophilic plants are not really aquatic plants, but they like to grow and live where there is water. Only when the roots remain moist for a long time can they flourish. Common plants include primrose, Hosta, Astillyrica, willow and other woody plants.
