Duckweed Source Plant Introduction, Distribution, and Growing Environment

Duckweed (scientific name: *Spirodela polyrhiza*) is an aquatic plant belonging to the Lemnaceae family. Below is an introduction to its source plant, distribution, and growing environment.

  1. Source Plant Introduction:
    1. Scientific Name: *Spirodela polyrhiza*.
    2. Other Names: Duckweed, Small Duckweed, Duck’s Mouth Grass, etc.
    3. Morphological Features: Duckweed is a small floating plant with green leaves that are smooth on the surface. The upper side is flat, while the underside has air chambers, allowing it to float on the water's surface.
    4. Reproduction: Duckweed primarily reproduces asexually and is known for its strong growth and ability to spread rapidly.
  1. Distribution:
    1. Duckweed is widely distributed in temperate and tropical regions worldwide, particularly in clear water environments such as lakes, rivers, ponds, reservoirs, and waterways.
    2. It thrives in sunny, calm water environments with clear water, such as ponds and streams.
  1. Growing Environment:
    1. Water Quality: Duckweed thrives in clear, clean water and cannot tolerate polluted conditions.
    2. Light Requirements: Duckweed prefers full sunlight, which enhances its photosynthetic activity and accelerates growth.
    3. Temperature Requirements: Duckweed grows best in water temperatures between 15°C and 30°C.
    4. Water Depth: Duckweed grows in water depths of approximately 1-3 meters, floating on the surface with roots extending underwater.

Duckweed, as a widely distributed aquatic plant, grows rapidly in suitable environments, providing oxygen to water bodies and helping purify water. However, excessive growth may lead to eutrophication, causing algal blooms that impact aquatic life. Therefore, proper management and control are necessary for maintaining water balance.

Duckweed Harvesting, Processing, and Storage

The harvesting, processing, and storage of duckweed are critical steps to maintain its quality for later use. The following provides information on duckweed harvesting, processing, and storage.

    2. Harvesting can be done by using boats or manual collection tools to scoop the duckweed from the water surface and place it in containers.
  1. Processing:
    1. After harvesting, duckweed should be immediately washed to remove dirt and impurities attached to the leaves.
    2. After washing, duckweed can be air-dried or soaked in water to ensure it is clean and free of excess moisture.
  1. Storage:
    1. For short-term storage, clean and dried duckweed can be placed in a well-ventilated, dry environment, avoiding direct sunlight.
    2. For long-term storage, duckweed can be dried further to reduce moisture content and stored in sealed containers in a cool, dry place.
  1. Precautions:
    1. During storage, periodically check the condition of the duckweed to ensure it is not moldy or deteriorating.
