The growth conditions of three kinds of aquatic plant was researched in purification experiments. We analyzed three different concentrations of eutrophic water and three species of aquatic plants, namely Acorus calamus, Typha orientalis and Iris tectorum. Nitrogen and phosphorus removal capacity of eutrophic water were analyzed.
The results showed that Typha...

The loss of nitrogen and phosphorus due to excessive fertilizer application has become a major form of agricultural non-point pollution. In order to explore the impact of different planting patterns (conventional cultivation, green rice-frog ecosystem and organic rice-frog ecosystem) on nitrogen and phosphorus loss, a field experiment in three paddy...

Key measures of eco-agricultural practices include landscape design at landscape level, circulation system design at ecosystem level and biological relationship design at community or sub-community level. Landscape design includes biological conservation design, resources utilization framework design, ecological safety design, and aesthetic landscape design. Circulation system design includes field circulation system,...
