Which aquatic plants are suitable for planting in the pond?

Fish pond culture is the first choice for freshwater fish culture. It can also optimize the fish pond environment, improve water quality and form a food chain of fish and plants. After reaching a certain scale, it is a good place for tourism, viewing and leisure fishing.

According to the lifestyle of aquatic plants, they are generally divided into the following categories: emergent plants, floating plants, submerged plants and floating plants.

The first is the emergent plants. Emergent plants are tall and colorful, and most of them have stems and leaves. Stand upright, the lower part or base of the plant is submerged in water, the roots or stems are plunged into the mud to grow, and the upper part of the plant is exposed to the water. There are many kinds of emergent plants, such as lotus, Juncus Juncus, Acorus calamus, Allium fistulosum, Sophora alopecuroides, Balagrass, Typha Typha, Alisma orientalis, Eclipta prostrata, reed and so on.

Second, floating plants. Floating-leaf aquatic plants have developed rhizomes. Floating-leaf plants have large flowers, bright colors, no obvious aboveground stems or weak stems that cannot stand upright, and their leaves float on the water. Common ones are Wang Lian, water lily, Pterocarya stenoptera, Euryale ferox, shepherd's purse and so on.

Third, floating plants. There are few species of floating aquatic plants. The roots of these plants are not born in mud, but float on the water. Floating plants drift around with the current and wind and waves, mostly for leaf viewing, providing decoration and shade for the pool water. Because they can not only absorb minerals in water, but also block sunlight in water and inhibit the growth of algae in water. 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. Water hyacinth culture in some places may face government fines.

Fourth, submerged plants. Submerged plants are rooted in mud, and the whole plant is immersed in water, which has developed ventilation tissue, which is beneficial to the exchange of submerged plants and gas. Most of the leaves are long, narrow or filiform, which can absorb some nutrients in water and grow normally under the condition of weak light underwater. There are certain requirements for water quality, because the turbidity of water quality will affect its photosynthesis and it cannot survive. Submerged plants play the role of "oxygen generator" in water, providing dissolved oxygen necessary for the growth of other organisms in the pond; At the same time, they can also remove excess nutrients from the water, thus keeping the water clear by controlling the growth of algae. Submerged plants include: black algae, Ceratophyllum japonicum, POTAMOGETON malayi, Sophora alopecuroides, POTAMOGETON crispus, etc.
