Ten species of floating plants, are floating plants aquatic plants

Water lily is a perennial floating-leaf aquatic herb of the family Nymphaeaceae and Nymphaeaceae, which is a common plant. The rhizome of the water lily is very thick, the leaf shape is oval, floating on the surface of the water, the leaf color is dark green, and the color of the back of the leaf is dark purple. The flowers of the water lily are solitary, floating or sticking out of the water.

Hyacinth is a plant of the family Yujiu and the genus Hyacinth, also known as water hyacinth, phoenix blue, and water hyacinth seedlings. The height of the plant is about 30-60 cm, the fibrous roots are relatively developed, the color is brown-black, and the length can reach about 30 cm. The leaves are clustered at the base and arranged in a rosette-like pattern, the leaves are rounded and have a dark green surface color.

The flowering leaves of the phoenix eye blue are multi-ridged, and the spike-like inflorescence usually has 9-12 flowers, and the petal color is purple-blue.

Duckweed is a floating plant of the duckweed family, duckweed, with green leaves and nearly circular shapes, obovate or obovate-oval.

It is a floating aquatic plant of the family Acacia and the genus Acacia Leaf Ping, with slender and horizontal stems and brown nodular hairs on the surface. The three lobes are whorls, the upper two leaves float on the surface of the water, and the lower one leaf hangs in the water, finely lobed into a line. The leaves are grassy in color, dark green on the surface, and densely covered with brown hairs underneath.

In addition, there are also large stalks, amphibian knotweeds, manjianghong, pingpeng grass, gourd, qiujiaoling, water turtle, water grass, Wang Lian, turnip, water weed, water weed, and so on.

Floating plants are aquatic plants, floating plants are floating leaf plants, containing more stomata, so that the leaves or plants can float smoothly on the water surface, typical floating plants have water lilies, eye plants, duckweed, water lotus, water hyacinth, etc., in which the plants with short root systems can float freely with the water flow, and the growth position of the plant rooted in the soil remains unchanged.

Floating plants are aquatic plants, floating plants refer to floating leaf plants, the body of the plant contains more pores, so that the leaves or plant body can float smoothly on the water surface, some of the varieties are completely floating on the water surface, and some varieties only have leaves floating on the water surface, and the root system grows in the soil.

Typical examples of floating plants are water lilies, eyeweed, duckweed, water lotus, water hyacinth, etc., their root systems generally lack oxygen, but because anaerobic respiration can produce alcohols, which supply oxygen to the roots through the petioles, their petioles are usually very long.

Some varieties of floating plants have very short roots and cannot be extended to the base part, so they can float freely with the water flow, such as locust leaf weed, duckweed, etc., and some varieties of roots can be rooted into the underwater soil, with wax film on the leaf surface, stomata located on the leaves, and good aeration tissue.

Aquatic plants are divided into five categories: upright plants, floating leaf plants, submerged plants, floating plants and wet plants, it is a general term for plants that can grow in water, the leaves of plants are usually soft and transparent, some are filamentous, and can increase the contact area with water.

Duckweed. Duckweed is a water surface planktonic plant of the order Araceae, duckweed, and duckweed.

phyllodes symmetrical, green on the surface, pale yellow or greenish-white on the back or often purple, entire, with 3 inconspicuous veins; 1 white filamentous root on the back; The phyllodes have a sac on the back, and the new phyllodes form a float in the sac, which is connected to the mother by a short stalk, and then falls off; 1 ovule in female flower; fruit nearly gyro-shaped; The seeds have a convex endosperm and longitudinal ribs.

Duckweed prefers warm climate and humid environment, avoid severe cold. Whole herbs can be used as feed for livestock and poultry. With the root of the whole herb into medicine, cold, pungent taste, function of diaphoresis rash, clear heat and water, the main treatment of surface fever, measles, edema and other symptoms.

Duckweed management methods.

1. Physical Methods:

When the biomass of duckweed is high, it is mainly limited by spatial factors, so after physical salvage, the growth space of duckweed can only be increased. That is, physical salvage will accelerate the growth and reproduction of duckweed, resulting in more and more fishing.

2. Chemical methods:

Commonly used chemical agents mainly include copper sulfate, permanganate, aluminum sulfate, ferrite composite agent, liquid chlorine, ozone and hydrogen peroxide. The use of chemical agents is undoubtedly an effective way to achieve remarkable results and quick results, but it is only a palliative method and must be used with caution.
