Abstract

The invention discloses a method of protecting water quality by using ecological ditches. The invention is characterized in that the method comprises: (1) digging inverted trapezoidal ecological ditches at drainage outlet of farmlands; (2) providing a plurality of holes at two walls and a bottom of the ecological ditches; (3) planting submerged plants in the holes at the bottom of the ecological ditches; and (4) planting perennial herbaceous plants in the holes at the two walls of the ecological ditches. The method solves problems of river eutrophication caused by N and P loss from the farmlands in prior art, and can relatively efficiently control non-point source pollution of farmland nitrogen and phosphorus by using the plants grown in the ditch walls to absorb and degrade nitrogen, phosphorus and other materials discharged from the farmlands and causing the eutrophication.

Description

A kind of method that adopts ecological canal protection water quality
Technical field
The present invention relates to a kind of method that adopts ecological canal protection water quality, belonged to the ecological protection technical field.
Background technology
The Taihu Lake basin area is along with the fast development of economy, the situation of the unreasonable use of farmland fertilizer and pesticide is day by day serious, a large amount of nutritive elements that run off enter the river, lake with the earth's surface runoff, cause very serious eutrophication phenomenon, especially N, the P loss from the farmland is the major reason that causes Taihu Lake and peripheral network of waterways body eutrophication.The measure of controlling at present N, P non-point pollution is mainly by escape canal, and soil property irrigation canals and ditches and concrete irrigation canals and ditches commonly used are very little to the interception result of N, P.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that adopts ecological canal protection water quality; by being planted in plant absorption on the irrigation canals and ditches wall and degraded from materials such as the nitrogen that causes water eutrophication of the discharging in farmland, phosphorus, non-some edge more effectively controlling farmland nitrogen, phosphorus pollutes.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is a kind of method that adopts ecological canal protection water quality, comprises the steps:
(1) dig at the farmland drainage mouth echelon form ecological irrigation canals and ditches that fell;
(2) be provided with a plurality of holes in two walls and the bottom of described ecological canal;
(3) kind is implanted with submerged plant in the hole of described irrigation canals and ditches bottom;
(4) kind is implanted with per nnial herb in the hole of described irrigation canals and ditches two walls.
A kind of aforesaid method that adopts ecological canal protection water quality, it is characterized in that: the bottom of described irrigation canals and ditches and two walls are concrete plate.
A kind of aforesaid method that adopts ecological canal protection water quality, it is characterized in that: described submerged plant is a kind of or its mixture in water caltrop, p.malaianus, hornwort.
A kind of aforesaid method that adopts ecological canal protection water quality is characterized in that: described per nnial herb a kind of or its mixture in Bermuda grass, trifolium, rye grass of making a living.
The invention has the beneficial effects as follows: by being planted in plant absorption on the irrigation canals and ditches wall and degraded from materials such as the nitrogen that causes water eutrophication of the discharging in farmland, phosphorus; can effectively raise the interception result to the nitrogen phosphorus of doing the mistake of industry face source and course; this ecological canal is simple in structure; easy and simple to handle, can widespread use and popularization in ecological recovery and protection.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.A kind of method that adopts ecological canal protection water quality, a kind of method that adopts ecological canal protection water quality comprises the steps:
(1) dig at the farmland drainage mouth echelon form ecological irrigation canals and ditches that fell;
(2) be provided with a plurality of holes in two walls and the bottom of described ecological canal;
(3) kind is implanted with submerged plant in the hole of described irrigation canals and ditches bottom;
(4) kind is implanted with per nnial herb in the hole of described irrigation canals and ditches two walls.
Select bottom and two walls of the concrete plate hardening irrigation canals and ditches of rectangle hole, the ecological canal cross section is isosceles trapezoid, upper wide 0.8-1.0 rice, lower wide 0.4-0.5 rice, dark 0.9-1.0 rice.
Described submerged plant can be any or its mixture in water caltrop, p.malaianus, hornwort.
Described per nnial herb any or its mixture in Bermuda grass, trifolium, rye grass of making a living.
Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
