First, what plants are there on artificial ecological floating islands?
Canna, moss, cattails, umbrella grass, ginger flower, red lotus seed grass, cyperus vulgaris, wild taro, purple taro, lythrum, Alisma, calamus, reed mushroom grass, cress, water spinach, Iris, water lily and myriophyllum, etc.
Second, the selection of plants for ecological floating islands, the selection of floating bed plants should follow the following principles:
1. Perennial aquatic plants suitable for growth under hydroponic conditions;
2, it has stain resistance, stain resistance and strong purification ability;
4. Developed root system, strong reproductive ability, fast growth and large biomass;
4. The landscape effect is good.
Commonly used floating bed plants include rice, ryegrass, canna, water bamboo (palm grass), reeds, cattails, shiitake grass, cress, water spinach, iris, water lilies and myriophyllum.
Among them, lentinus edodes is a gramineous perennial plant with developed root system, large biomass, high nitrogen and phosphorus nutrients, both terrestrial and aquatic characteristics, and strong adaptability. It has "three materials" (raw materials, feed, fuel) Its biomass can reach 750t/(hm·a), which has a good purifying and repairing effect on the trophic water body.
The selection and combination of floating bed plants also need to consider the seasons, so that it still has a certain purification effect and landscape effect under unfavorable seasons (such as winter). The plants planted above are generally aquatic plants, but some terrestrial plants with strong water tolerance, large biomass and good landscape effects are also used.
