CATDOLL : CATDOLL: What are the plants in the sewage treatment pond? What is their function?

1. What are the plants in the sewage treatment tank? What is their function?

Without mud, trees cannot be planted. We can only grow some aquatic plants or water grasses on the water surface, such as water hyacinth, duckweed, vallisneria, verticillata, hygrophila, chrysanthemum grass, foxtail grass, red lotus seed grass, jade flower, variegated reed, European reed, umbrella grass, pickerel grass, purple stem taro, lily, European arrowhead, yellow iris, variegated water plantain, water lily, lotus, loosestrife, oriental water plantain, cattail, etc.

2. Why can some plants grow underwater without being corroded?

Aquatic plants have evolved over a long period of time to adapt to life in water. They can exchange gases in water, absorb nutrients, and perform photosynthesis under dim light.

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

Emergent plants: lotus, reed, cattail, zangbo, water plantain, reed, calamus, cattail, black trifoliate, water candle, Alisma orientalis, sagittaria, etc.

Floating leaf plants: spring pondweed, bamboo-leaf pondweed, water lily, water chestnut, water caltrop, water caltrop, Victoria regia, etc.

Wetland plants: canna, pickerel grass, loosestrife, water lily, aquatic iris, red polygonum, pennisetum, cattail, etc. plants suitable for growing near water.

Submerged plants: silk-leaved pondweed, thread-leaved pondweed, water cabbage, sea cabbage, sea calamus, valuable grass, duckweed, water plantain, spike-flowered foxtail algae, black algae, etc.

Floating plants: duckweed, purple-backed duckweed, water hyacinth, giant hyacinth and other plants.

Emergent plants

Emergent aquatic plants are tall and colorful, and most of them have stems and leaves. They are upright, with the lower part or base submerged in the water, the roots or underground stems growing in the mud, and the upper part of the plants rising above the water. There are many kinds of emergent plants, the most common of which are lotus, Lythrum salicina, Acorus calamus, Iris calamus, Onion, Zygophyllum, Pike, Phragmites australis, Cattail, Alisma orientalis, Cyperus rotundus, Phragmites australis, and Zizania latifolia. Emergent monocot plants often have small transverse veins.

Floating Leaf Plants

Floating-leaf aquatic plants have well-developed rhizomes, no obvious above-ground stems or stems that are too thin to stand upright, and leaves that float on the water. Common species include Victoria amazonica, water lily, water lily, Euryale ferox, Nymphoides, water poppy, etc.

Plants in the genera Nuphar and Nymphaea, which have roots on the bottom of the pond and flowers and leaves floating on the surface, are not only very beautiful in their own right, they also provide shade for pond life and limit the growth of algae.

Submerged plants

Submerged aquatic plants have their rhizomes grown in mud, and the whole plant is submerged in water. They have well-developed aeration tissues, which facilitate gas exchange. Most of their leaves are narrow or filamentous, and can absorb some nutrients from the water. They can also grow and develop normally under weak light conditions underwater. They have certain requirements for water quality, because turbid water will affect their photosynthesis. The flowers are small and the flowering period is short (except for some plants), and they are mainly for viewing leaves.

Submerged plants, such as Lagaro-siphon or Myriophyllum, act as "oxygen generators" in the water, providing dissolved oxygen necessary for the growth of other organisms in the pond; at the same time, they can also remove excess nutrients in the water, thereby keeping the water clear by controlling the growth of algae.

Excessive algae can cause the water to become cloudy and green, and block the light necessary for the healthy growth of aquatic plants and pond organisms. Submerged plants include: Hydrilla verticillata, Ceratophyllum, Potamogeton, Vallisneria, Waterweed, Sea lettuce, Sea lettuce, etc.

Water plants

These plants grow along the edge of a pond, from a depth of 23cm to the mud at the edge of the pond. There are many varieties of water edge plants, which are mainly ornamental. Water edge plants planted along the edge of a small wildlife pond can provide a hiding place for water birds and other animals that visit the pond.

Water edge plants growing under natural conditions may spread in patches, but after transplanting to the edge of a small pond, as long as they are pruned regularly and the spread of roots is controlled in a planting pot, there will be no problem. Some prefabricated ponds have shallow water areas, which are specially prepared for water edge plants. Of course, plants can also be planted in flat-bottomed planting pots directly in the shallow water area.

Moisture-loving plants

This type of plant grows in moist soil near a pond or stream, with its roots completely immersed in water. Hygrophilous plants are not true aquatic plants, but they like to grow in places with water. They can only grow vigorously if their roots are immersed in water for a long time. Examples include hygrophilous grass, round-leaved bladderwort, calamus, and golden money cattail.

Floating plants

There are fewer types of floating aquatic plants. The roots of these plants do not grow in the mud. The plants float on the water surface and drift with the currents, wind and waves. Most of them are mainly for viewing leaves, providing decoration and shade for the pool water. Because they can absorb minerals in the water and block the sunlight that enters the water, they can also inhibit the growth of algae in the water.

It can provide a faster cover for the water surface. However, some species grow and reproduce very quickly and may become a nuisance in the water, such as water hyacinth. Therefore, it is necessary to regularly scoop out some with a net, otherwise they will cover the entire water surface. In addition, do not introduce such plants into a large pond, because it will be very difficult to remove such plants from a large pond.

3. What are aquatic plants?

Plants that grow in water are collectively called aquatic plants, which are generally divided into the following categories: emergent plants, floating leaf plants, submerged plants, floating plants and wetland plants.

1. Emergent plants: lotus, reed, cattail, foxtail, water plantain, reed, calamus, cattail, black trifoliate, water candle, Alisma orientalis, Sagittaria, etc.

2. Floating leaf plants: spring pondweed, bamboo-leaf pondweed, water lily, water chestnut, water caltrop, water caltrop, Victoria regia, etc.

3. Wetland plants: canna, pickerel grass, loosestrife, lily, aquatic iris, red polygonum, pennisetum, cattail, etc., plants suitable for growing near water.

4. Submerged plants: silk-leaved pondweed, thread-leaved pondweed, water cabbage, sea cabbage, sea calamus, Vallisneria, duckweed, water plantain, spike-flowered foxtail algae, black algae, etc.

5. Floating plants: duckweed, purple-backed duckweed, water hyacinth, giant hyacinth and other plants.

4. Are there more aquatic plant species or terrestrial plant species?

It’s different for different age groups!

Nowadays, most of them should be terrestrial.

Hundreds of years ago, thousands of years ago... (I'm not sure how many years ago), there should have been more aquatic plants, because the primitive ocean was the original cradle of life!

5. What can the mysterious fruit in Expedition produce?

The first fruit you pick in the morning may give you one of the following rewards: Rain, Pickerel Grass, Vitality Pill, Power Flower, Cattail, Water Hyacinth, or Crystal.

When you shake it, you will get the following: crystals, essences, gold coins

Everything depends on the machine, you know~
