The most effective aquatic plants for improving water quality Which plant is the best for purifying water?

Water is an indispensable substance in human life. Of course, it is also very important to maintain the quality of water. When cultivating aquatic plants for water greening, choosing the right materials is fundamental.

To achieve both landscape effect and effective water purification, plant configuration should also pay attention to the principles of garden aesthetics. Here are some aquatic plants that can purify water.

Aquatic plants that purify water

1. Reed

   Phragmites australis belongs to the Poaceae family and can be propagated by sowing or division. It has a good effect in purifying water quality. If the reeds are arranged on the natural waterside, it will have a unique wild charm.

2. Lotus

   The genus Nymphaea is a perennial aquatic plant of the Nymphaeaceae family. It is propagated by division or sowing. The lotus has beautiful flowers and leaves and is fragrant. It is a good plant material for beautifying the water surface, decorating pavilions, or potted plants.

3. Duckweed

  Duckweed, also known as green duckweed, can absorb and accumulate a large amount of heavy metal elements in the coal washing wastewater of power plants, and can effectively absorb, accumulate and decompose nutrients and various organic pollutants in the wastewater.

4. Water onion

   It is a perennial aquatic herb of the genus Cyperaceae with tall, straight, and lush green stems. Its variant, the variegated water plantain, has yellow ring spots on its stems and has a certain ornamental value. Water plantains are mostly propagated by division in early spring, and shallow water is preferred in the early stages of planting. The stems of water plantains are tall and lush green, and are often used for water surface greening or as a shore decoration.

5. Cattail

The genus Typha is a perennial marsh herb of the family Typhaceae, propagated by division. Its cattails can be used as cut flowers or dried flowers.

Configuration principles of water features and aquatic plants

The spread of planted plants should be strictly controlled. Green belts can be set up for isolation, or they can be planted in water. When using aquatic plants for water greening, first of all, the materials should be selected well, and efforts should be made to achieve both landscape effects and effective water purification. Secondly, the arrangement of plants should pay attention to the principles of garden aesthetics, and the following aspects should be paid attention to:

1. The distance between aquatic plants and the water's edge should be far or near, sparse or dense. Avoid planting them at equal distances along the edge, and leave necessary perspective lines.

2. Pay attention to the coordination between the three-dimensional outline of the plant community and the style of the waterscape.

3. The mirror effect of the water surface should also be considered. The plants on the water surface should not be too crowded, and generally should not exceed one-third of the water surface. This will not affect the reflection effect of the water surface and the aesthetic effect of the water body itself. For water surfaces with little visual effect, the density of plants can be increased to form a green landscape.
