Description
Technical field
The present invention relates to a kind of drainage systems, and in particular to a kind of draining system suitable for knob rain shelter cultivation mode
System.
Background technique
With the development of economy with the increasingly raising of living standards of the people, people are continuously increased the demand of crop, and
And more stringent requirements are proposed to the quality of crop.In south, since high temperature and rainy, air humidity are big, traditional outdoor cultivation
Not only fungal disease is serious, control cost is high for mode, and fruit quality is poor, is difficult to adapt to fierce market competition, to limit
High-quality crop has been made in a large amount of development of southern area.Seasonal excessive rainfall, which has become, restricts southern area part cultivation work
Object is high-quality, high yield important restriction factor.Rain shelter cultivation is that one kind of southern region of China industrial crops cultivation in recent years is main
Form is used widely in Southern Fruit Trees and crop production, and achieves certain effect.
Existing Water drainage system design is designed also according to the mode of plains region iirigatio region planning substantially, is only considered
Side slope, flow, flow velocity the problems such as.Although traditional drainage system mode is relatively applicable in Plain Irrigation District, rain shelter cultivation
Mode changes the original confluence mode of rainwater due to taking shelter from rain using rain cover film, and rainwater first collects on film taking shelter from rain, then
Side along film of taking shelter from rain flows down, and not only flow rate of water flow is fast, but also strong to the water flow impact pressure on ground, if being without matched draining
System, easily causes soil erosion, larger for the farmland quality damage in hills arable land.
Summary of the invention
Goal of the invention: to overcome the shortcomings of the existing technology, the present invention is directed to provide a kind of be suitable for knob rain shelter cultivation mould
The drainage system of formula.
Technical solution: in order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of drainage system suitable for knob rain shelter cultivation mode, including film of taking shelter from rain, farm ditch, ground collection surface, bucket
The drop of trenches and mesas rank；The film of taking shelter from rain is located at arable land top, and film top surface collection surface of taking shelter from rain is arc surface, and farm ditch, which is located at, takes shelter from rain under film
The arable land two sides of side, farm ditch length direction are consistent with film length direction of taking shelter from rain；Ground collection surface is located on the outside of farm ditch, and ground is collected
It is tilted towards farm ditch side；Bucket ditch intersects vertically with farm ditch, and step drop is located at elevation between bucket ditch and adjacent arable land and becomes
At change.
Above-mentioned farm ditch and adjacent side of ploughing are inside, and non-conterminous side is outside.
Working principle: the present invention is suitable for the drainage system of knob rain shelter cultivation mode, and arable land top passes through film of taking shelter from rain
Top surface collection surface Accumulated Rainwater is discharged into the farm ditch of two sides, will not cause to wash away sputter to arable land surface；For arable land surface and plough
The rainwater on ground is discharged into farm ditch by ground collection surface confluence other than ground, and the setting step between ditch and arable land that struggles against, which drops, carries out energy dissipating
Processing reduces the downstream soil erosion because caused by increasing elevation drop.
The bucket ditch is located at the centre of farm ditch length direction；The trench depth that struggles against is equal with farm ditch, and bucket ditch width is the 2-3 of farm ditch
Times, bucket ditch can be made to accept the water flow of upstream and farm ditch.
The step drop includes step vertical face and step transverse direction face；Step vertical face perpendicular to the ground, step transverse direction face
It tilts inwardly, tilt angle is 10-25 °, is able to achieve water flow rolling and carries out energy dissipating, under reducing caused by increasing because of elevation drop
Swim soil erosion.
Above-mentioned inside is that step drops and adjacent side of ploughing.
It is 0.5 ° -2.5 ° that the ground, which is collected towards the inclined inclination angle of farm ditch side,；It can guarantee that rainwater can converge
In road farm ditch.
The section of the film collection surface of taking shelter from rain is intersected with ditch bottom layer width center, can guarantee that rainwater can collect along film of taking shelter from rain
Surface current enters in farm ditch.
The farm ditch includes filter layer, baffle, Gou Po and ditch bottom；Ditch bottom is farm ditch bottom, and ditch slope is located at ditch bottom
Two sides, filter layer are located at ditch top of the slope end, and baffle is located on the inside of filter layer and baffle connects with ditch top of the slope end.
It is two filter layer opposite faces on the inside of above-mentioned filter layer.
The filter layer is triangular in shape, and filter layer divides upper layer and lower layer, and upper layer is covered with the cobblestone of partial size 20-50mm, lower layer
It is covered with the sandstone of partial size 10-20mm；It is distributed according to partial size is descending, partial size larger main function in top is prevented with water
Stream flowing, partial size smaller main function in lower part is to be filtered.
It is attached to using geotextiles close to the baffle side of filter layer between the filter layer baffle, baffle uses grid
Formula；Further filtering is realized and reduces the effect that soil flows away with water flow；Baffle uses grid, has both realized good
It is aqueous, also ensure the stability of filter layer.
The ditch bottom uses different-grain diameter cobble river bottom protection, and ditch bottom top is covered with the cobblestone that partial size is 50-100mm,
Lower part is covered with the cobblestone that partial size is 20-50mm；It can top be respectively the impact for reducing film collection surface water flow of taking shelter from rain, lower part is
Cover ditch substratum, reduction washes away, while can the cobblestone to top carry out reinforcement fixation.
The unmentioned technology of the present invention is the prior art.
The utility model has the advantages that the present invention is suitable for the drainage system of knob rain shelter cultivation mode, rainwater meeting can be made when rainy
Favourable exchange collection surface current enters in farm ditch, will not cause to wash away sputter to arable land surface；The rainwater conflux on arable land surface, rainwater can be passed through
Filter layer flows into farm ditch, and the soil that filter layer sweeps along rainwater filters, and can be reduced the loss of field soil fertility；Can be reduced because
Downstream soil erosion caused by the increasing of elevation drop.
