The traditional design of plants used for floating islands is mainly based on the selection of aquatic plants or plants with strong water adaptability. When selecting, not only need to screen the corresponding aquatic plants for the treatment of different pollution sources, but also consider the characteristics of the plants themselves. Preferences, such as Cigu and wild taro, like nutrient-rich water bodies. If the water bodies are too clean, they will grow poorly because of insufficient nutrition.
In addition, consideration should be given to the selection of plants in different niches of the aquatic plant community, such as small trees for the construction of aquatic forest communities, such as the ash bellows tree, Jiuxiong, water yellow bark, etc.; the dwarf herbaceous plants for the construction of land, such as aquatic millet , Wingless sedge, mud moss, small leaf sea golden sand, etc. The introduction of these plants can form a grass blanket, which is beneficial to attract insects, butterflies, and birds, and create a natural ecology of multiple species; the construction of watery aquatic plants, such as water hair flowers The introduction of these plants can be used as insect herbivores to facilitate their emergence and facilitate the completion of insect generations; plants supporting floating structures, such as ike grass, bamboo grass, cloth bags Lotus, long-stemmed gypsophila and other plants with floating water sacs can enhance the floating capacity of the grass carpet.
