Aquatic plants refer to those plants that can live normally in water for a long time. Aquatic plants are excellent swimmers or divers. They live in water all the year round and form a set of skills to adapt to the aquatic environment.

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

emergent aquatic plant

Emergent plants are tall and colorful, and most of them have stems and leaves. Erect, erect, undersurface or basal emergent plants.

Partially submerged in water, roots or stems plunge into the mud to grow, and the upper plants are 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.

floating vegetation/plant

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.

Floating plants are: water lilies, shepherd's purse, soft-shelled turtle, Euryale ferox and so on.

Floating vegetation/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. 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 in the 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. 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.

Submerged plants include: black algae, Ceratophyllum japonicum, POTAMOGETON malayi, Sophora alopecuroides, POTAMOGETON crispus, etc.

submerged plant

Submerged plants are rooted in mud, and the whole plant is immersed in water, which has developed ventilation tissue, which is beneficial to the gas exchange of submerged plants. 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 water turbidity will affect its photosynthesis. Flowers are small and short-lived, and are mainly used for leaf viewing.

Submerged plants, such as Lagaro-siphon or Myriophyllum, play the role of "oxygen generator" in water, providing necessary dissolved oxygen 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. Excessive algae will lead to turbid and green water quality, blocking the light necessary for the healthy growth of aquatic plants and pond creatures. Floating plants, such as Azolla or Eichhornia crassipes, can also absorb nutrients dissolved in water through slender roots. Deep-water plants, such as Nuphar and Nwnphaea, have their roots at the bottom of the pond and their flowers and leaves float on the water. They are not only very beautiful, but also provide shade for pond creatures and limit the growth of algae.

water plant

This plant grows on the edge of the pool and can grow from the depth of 23cm to the mud beside the pool. 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 the soil near a pool or stream that likes wet plants, but its roots can't 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. Mangrove plants.

Planting floating plants

When planting floating plants such as water lilies or water chestnuts, it is necessary to fill the bottom of the container with soil or mud to plant roots or underground stems, and the water depth is about five centimeters or more; Mini water lilies only need two centimeters of shallow water. Adequate sunshine is very important for the growth of water lilies. Insufficient sunshine will not only make the stems and leaves grow in vain, but also make the leaves smaller and thinner, which will also affect the number of flowers. Flowers bloom in the daytime, and as long as they are moved to a place with insufficient sunshine indoors, the flowers will be closed immediately. For Mr. Zhang who lives in Guishan Township, space is not a problem. In order to seek the most comfortable living environment for his beloved aquatic plants, he invented the method of making a simple pool. It is economical and convenient to use hollow bricks to surround the edges and a piece of plastic tape to lay the bottom. The size can be adjusted freely, and it can even be built in the courtyard or top floor of the house. Common water lilies are all horticultural varieties selected by hybridization. According to its growth habits, it can be divided into four categories: tropical daytime flowers, tropical night flowers, temperate cold-resistant flowers and mini water lilies, including white, yellow, purple and pink. Among them, mini water lilies are the most common, with the largest leaf diameter of eight to ten centimeters, which requires little space and is more suitable for living in narrow and densely populated cities.
