What are the principles for selecting ecological floating island plants? Cultivation of plants on ecological floating islands is very important, because plant growth characteristics are different from terrestrial cultivation, mainly in the changes in biomass, plant height, chlorophyll content and root vitality. This difference is mainly due to hydroponics. Nutrients, temperature, humidity, etc. are different from those of land plants
Due to the strong regional nature of plants, special attention should be paid to the selection of native aquatic plants or amphibians in the selection of plants. In the north, you can choose reeds, lythrum, etc.; in the south, you can plant calamus, water celery, and agaric. At the same time, try to use perennial herbs to reduce maintenance costs. Exotic plant species should be properly controlled. Water hyacinth plants have obvious effects in purifying water quality and plant landscape. However, because it is very easy to spread and is not easy to control, this kind of plant should be reasonably controlled and treated in time.
2. The effect of phytoremediation.
13 kinds of emergent plants with strong nitrogen and phosphorus removal ability: canna, moss, cattail, turban, ginger flower, red alternaceae, sedge, sedge, wild taro, purple taro, lythrum, lythrum Diarrhea, calamus. Sophora japonica and duckweed have strong ammonium nitrogen removal ability.
