Description
Technical field
It is specifically a kind of to be prevented and treated for agricultural non-point source pollution the present invention relates to a kind of technology of field of environment protection
, the agricultural ecological drainage ditch construction method that furrow bank soil losses can be prevented.
Background technique
Agriculture drainage ditch is the water channel that agricultural drain (flood discharge) is used for positioned at road both sides or field, and forming process is just
It is the water passage that the mankind are the needs such as satisfaction production, living safety guarantee and hand digging.Drainage ditch is that a kind of mankind are living
The wetlands ecosystems of semi-naturalization under the influence of dynamic have important influence to agricultural production and ecological environment, are farming regions
Common landscape feature.The irrigation and drainage function of irrigation canals and ditches is the important leverage of agricultural production and ecological safety, with water environmental problems
Get worse, irrigation canals and ditches water environment pollution prevention and treatment and in terms of effect start to cause to pay close attention to, become
Mitigate one of effective ways of farmland non-point pollutions such as nitrogen, phosphorus and pesticide.
Research relevant to agriculture drainage ditch is in developing stage both at home and abroad, has obtained some research achievements.It is related
Studies have shown that irrigation canals and ditches are to agricultural production, and it is especially extremely important to the agricultural production in impeded drainage area, it is to improve agricultural production
One of effective measures of power；As water passage, sewerage affects the precipitation allocation and discharge series process in basin, and controls
Make the WATER LEVEL CHANGES of Farmland；Irrigation canals and ditches have the landscape feature of river and wetland characteristics simultaneously, can be aquatic and wet
Lively plant provides habitat, greatly affects the bio-diversity in region；In addition, as a kind of artificial swamp, irrigation canals and ditches can
Effectively to be retained and be converted caused by agricultural production by processes such as plant absorption, sedimentation, chemical conversion and microorganism conversions
Pollution of area source is to reduce one of pollution of water and the effective way of eutrophication.Correlative study shows Demonstration for Ecological Sanitation irrigation canals and ditches
Have a good Farmland Flow Pollution object interception effect, the agricultural ecological drainage ditch system of reasonable construction to paddy field runoff TN,
TP pollutant interception amount is respectively up to 1.6kg/ mus of years, 0.04kg/ mus of years, to nonirrigated farmland runoff TN, TP pollutant interception amount
Respectively up to 0.9kg/ mus of years, 0.06kg/ mus of years, pollution of river burden is greatly alleviated, eutrophication wind is reduced
Danger.
It sees on the whole, traditional cement backplate drainage ditch is unable to effectively catching, removes the pollutant in the rainfall runoff of farmland
Matter does not have biological habitat function, and landscape quality is single, cannot form good ecological effect；The ecology row constructed at present
The bright ditch tool of the relatively traditional cement of Box Drain system is greatly improved, and has not only restored irrigation canals and ditches habitat, and to agricultural run-off
Pollutant has good clean-up effect.But knot is monitored to existing conventional circular hole irrigation canals and ditches side plate ecological canal long-term follow
Fruit discovery, after it experienced use in several years, the effects of due to draining and flushing and immersion, irrigation canals and ditches side soil by circular hole gradually
It is lost, soil is emptied after eventually leading to backplate, a large amount of soil siltation trench bottoms, while side water plant loses attachment
Face, gradually withered death, loses the vitality and detergent power at irrigation canals and ditches building initial stage.
Summary of the invention
The present invention for prior art construction is unstable, service life is short, furrow bank soil is easy to run off, irrigation canals and ditches be easy siltation,
The defects of maintenance management is inconvenient proposes a kind of agricultural ecological drainage ditch construction method for preventing furrow bank soil losses, has
Simple and practical, stable structure avoids furrow bank soil losses, to Farmland Flow Pollution object good purification and has good scape
The features such as seeing effect.
The present invention is achieved by the following technical solutions:
Then the present invention is joined by carrying out edit to former drainage ditch in agricultural drain mouth and Demonstration for Ecological Sanitation irrigation canals and ditches
Place's setting sump, agricultural run-off after preliminary sedimentation, enter Demonstration for Ecological Sanitation irrigation canals and ditches through effluent weir in sump；It is arranged to ecology
The bottom of trench of Box Drain is boxed out on the basis of solidification and the processing of furrow bank slope, then with porosity Demonstration for Ecological Sanitation irrigation canals and ditches side plate to Demonstration for Ecological Sanitation
Irrigation canals and ditches side slope carries out consolidation process, and plantation purification is planted in the reserved plant agricultural climate condition for corn hole of the side slope of Demonstration for Ecological Sanitation irrigation canals and ditches and bottom
Object；Waterwall finally is set in Demonstration for Ecological Sanitation irrigation canals and ditches end, farmland rainfall runoff is made to enter river after the purification of Demonstration for Ecological Sanitation irrigation canals and ditches.
Technical effect
Compared with prior art, present invention selection discharge capacity is strong, nitrogen and phosphorus pollutants are amputated with high-efficient aquatic, humidogene
Plant and reasonable collocation mode, construct the families of plant of ecological canal, and effectively catching can be effectively reduced, remove in agricultural run-off
The polluters such as nitrogen, phosphorus restore bio-diversity, build the good ditch wetland ecosystem.Meanwhile it is relatively existing general
Circular hole Demonstration for Ecological Sanitation irrigation canals and ditches, pellet type, combined type and venetian blind type ecological canal side plate proposed by the present invention can be solved effectively
Emptied after certainly general circular hole drainage ditch side plate, soil erosion the problems such as, improve ecological canal water and soil conservation ability, preferably
Plant habitat is built, irrigation canals and ditches service life is extended, provides better Farmland Flow Pollution clean-up effect, while establishing more perfect
Farming landscape keeps having even more important meaning for Farmland Flow Pollution prevention and treatment and farmland ecosystem.
