The filling layer is composed of coconut palm and straw, which provides nutrients for the growth of aquatic plants. The plant production layer can meet the requirements of normal plant growth. Usually, a mixed soil lighter than natural soil is used, which includes organic fertilizers, humus, cultivated soil and other composite components. Such a soil combination can reduce the total load value of the roof and provide the nutrients required by the plants. The microorganisms in the microbial activity layer mainly include bacteria, fungi, actinomycetes, etc. They decompose organic matter in the soil and convert it into inorganic nutrients that can be absorbed and utilized by plants, such as nitrogen, phosphorus, potassium, etc. In addition, the microorganisms also participate in the formation and stabilization of soil organic matter and the formation of soil aggregates, which helps to improve the soil structure and improve the soil air permeability and water retention.
