    the weather with “ &rdquo to describe, perspiration comes down like raindrops; it is not a little exaggeration. The big bridge, passers-by in a hurry to depart. However, the reporter standing on the bridge and looked to the sides, but was stunned in front of a scene: in front of a piece of green, on both sides of the floating bed flower “ ” like two green belts along the inner sides of the Qinhuai River spreading.

They had underwritten 50 thousand yuan to do this project, in order to be able to affect the river water, planting basket are arranged at intervals. “ these aquatic plants can absorb sediment and some nutrients in the water, but it is not realistic to completely rely on them. &rdquo, the official said, at present, the degree of purification of aquatic plants on the water exactly how, still in the course of the study, no one can give a final conclusion. “ ‘ biological water purification ’ only one of the means to make the water clear, it can not replace other governance. ” for the current situation of plant growth, the person in charge said with a smile: “ this shows that the Qinhuai River's water is still quite ‘ nutrition &rsquo. ” they had done similar experiments in Fujian, Quanzhou, but the plant was not growing well.
