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

The phyllodes are symmetrical, the surface is greenish and colored, the back is light yellow or greenish-white or often purple, the whole margin, 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 embryonic pararidge 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 by-seepage.

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.
