What are the plants floating on the water?

Water lily (scientific name: water lily? Perennial aquatic herbs; Hypertrophy of rhizome. Petiole cylindrical, slender. The leaves are oval, floating on the water, with the whole margin, heart-shaped base, dark green surface and deep purple back. Leaf type 2: floating leaves are round or oval, with curved base, heart-shaped or arrow-shaped, often without water; Submerged leaves are thin and brittle.

2. Eichhornia crassipes

Floating grass, 30-60 cm tall. Fibrous roots are developed, brown and black, up to 30 cm long. The stem is very short, the creeping branches are long, light green or purplish, and grow into new plants after leaving the mother plant.

3. Duckweed, also known as Green Duckweed, Tian Ping, Duckweed, Duckweed, Duckweed, is a floating plant on the water surface of Duckweed family. I like warm climate and humid environment and avoid cold.

Floating plants, also known as completely floating plants, are floating plants that cannot be rooted in sediments and float on the water. The roots of these plants are usually underdeveloped, and ventilation tissues have developed in the body, or there are swollen petioles (air sacs) to ensure gas exchange with the atmosphere. Such as Sophora japonica leaves, duckweed and Eichhornia crassipes.

There are few species of floating aquatic plants. The roots of these plants are not born in mud, but their plants 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. Because they can absorb minerals in water. At the same time, it can block the sunlight injected into the water, so it can also inhibit the growth of algae in the water.

Floating plants grow fast and can provide covering decoration on the water surface more quickly. However, some species grow and reproduce very rapidly and may become pests in water. Therefore, it is necessary to regularly fish out some with a net bag. Otherwise, they will cover the whole water surface. The following are some of the most common floating aquatic plants.
