Description
Technical field
The present invention relates to a kind of of plant irrigation, i.e. the method for infiltrating irrigation.
Background technology
Irrigate and generally be divided into furrow irrigation, border irrigation, sprinkling irrigation, drip irrigation, infiltrating irrigation, pouring etc.
(1) furrow irrigation method is namely in the ranks ditched between the ridge and is poured water.
(2) border irrigation method is that irrigation water is introduced in the furrow ditch, and current are infiltrated in the soil gradually.
(3) sprinkling irrigation, drip irrigation method are the novel irrigation methods of development in recent years.Sprinkling irrigation is that the pressure water that is formed by water pump pressurization or natural-drop is delivered to the field by pressure pipeline, is ejected in the air through shower nozzle again, forms fine liquid particles, trickles down equably in the farmland, reaches the purpose of irrigation.Drip irrigation is to make irrigation water slowly splash into table soil, soaks into the root soil of crop.
(4) infiltrating irrigation refers to by related facility with water directly sending into below the table soil slowly, to infiltrate the irrigation method of root layer soil.
(5) pouring method is watered with kettle or leather hose etc.
Wherein infiltration irrigation technology has the advantage of significant water saving, energy-conservation, saving of labor, volume increase and raising product quality, and the availability of water is the highest in all irrigation techniques at present, and that its subject matter is silting is serious, is difficult to overcome.Its implementation method is a lot, use roughly can be divided into two kinds of point type and line formulas at present in the land for growing field crops, point type (claiming again outlet type) is exactly with fluid-tight plastic tube water to be delivered to plant root, irrigates by a kind of head that oozes that is embedded in underground slowly water seepage then.Line formula (claiming again full wall type) is to adopt to be embedded in the underground pipeline that can slowly outwards seep water and directly to irrigate, and this soakaway trench is divided into two kinds of antipriming pipe and microporous pipe.Antipriming pipe is to beat a lot of apertures (aperture is 1-2mm) or the long longitudinal joint of 5～10mm on tube wall, and microporous pipe is the pipeline that pulls into special material (rubber that junked tire reclaims, plastics etc.), and countless foamed micropores are arranged on the tube wall.In pipe, will ooze out as perspiration gradually during water-filling, irrigate.In recent years report that more a kind of infiltrating irrigation pipe is after utilizing admixtures such as waste and used rubber tyre powder, PVC molding powder and blowing agent to mix, through the soakaway trench that has a large amount of micropores on tube wall of special technique PROCESS FOR TREATMENT extrusion modlings such as foaming, uvioresistant.With water invisible micropore of naked eyes from the soakaway trench tube wall, press seepage flow moistening its surrounding soil that comes out by pressure as perspiring.Want the setting pressure device like this at the water source; Because the infiltrating irrigation micropore is relatively poor for the permeability of air, need settle exhaust apparatus simultaneously at infiltrating irrigation pipe afterbody.
With regard to adopting above-mentioned this micropore infiltrating irrigation pipe to carry out plant filtration irrigation, also there are some following problems, promote to such an extent as to be difficult to large tracts of land:
1, in a single day whole system complexity comprises the pressure apparatus at water source, every facility cost height such as exhaust apparatus of infiltrating irrigation pipe afterbody, and stops up, cleaning, maintenance and management are all very difficult, and therefore not only use cost is too high, and and inconvenience.
2, adopt this irrigation method, though the EXIT POINT dispersion is irregular, and the hole pipe is not of uniform size, utilizes press water to carry out infiltrating irrigation, is the mode diversion by supercharging, output to soil is difficult to control, in fact still can be because of the waste water yield not of uniform size of hole pipe.
3, since whole pipe all the infiltration, not only cause water resource waste, and remain moistening easy growth of weeds in the plant gap.
4, the silt in the soil stops up the micropore of soakaway trench easily, and if the infiltration micropore is stopped up or the factors disrupt such as insect bite after, its water percolating capacity is done wet irregular, and can not in time find, water and soil soil moisture conservation poor performance is unfavorable for the g and D of crop.
5, silt silting problem is not only arranged, also have biological the obstruction, this defective can not solve always.
Summary of the invention
Purpose of the present invention is exactly to solve the problems such as the easy silting, the investment that exist in the present infiltration irrigation technology are big, and a kind of anti-blocking automatic filtration irrigation method is provided, and is convenient to actual applying.
The concrete technical scheme that the present invention taked is as follows:
A kind of anti-blocking automatic filtration irrigation method, this method be by with the contacted seepage matter in water source to the plant root soil water delivery.
Above-mentioned anti-blocking automatic filtration irrigation method, described water source are meant can provide water to the infiltration thing, promptly can make a termination of infiltration thing contact water.Whole water delivery or water storage system that it comprises water delivery source, water delivery or water storage facility can be aqueduct, tank and the whole systems such as other water delivery or tank of running water, water delivery.
The present invention can directly use running water, controls the source to the aqueduct water delivery by water valve, then provides the water source to the seepage matter that is connected with aqueduct; Also tank, pond etc. can be built, even pond nearby, ditch that surface water forms etc. can be adopted.Greatly widened in a word the collection at water source, the application of this filtration irrigation method is further promoted.
Above-mentioned anti-blocking automatic filtration irrigation method, described seepage matter can be divided into two classes, and a class is the object that can form capillarity, preferably fictile; Another kind of is the object that can form siphonage and have the anti-filter function, preferably geotextiles.Preferred scheme is that the weight composition and ratio of fictile is: potter's clay 55～75%, diatomite 5～35%, powdered carbon 5～35%, each composition is mixed by proportioning, and about 1000-1100 ℃, fire to form then and get final product; Geotextiles adopts 300-800g/m
2Polyethylene or pp geo textiles.
To the soil water delivery, water delivery speed is slowly but unusually even, stable, substantially is not subjected to the impact of hydraulic pressure, can also automatically regulate carrying capacity according to the soil moisture content that contacts with seepage matter simultaneously by capillarity for front a kind of seepage matter; To the soil water delivery, water delivery speed is more front a kind of fast by siphonage for rear a kind of seepage matter, and can be subjected to the impact of hydraulic pressure.
No matter use which kind of seepage matter, water can only can not spill from the interface of seepage matter and other device by seepage matter output, certainly, how with the water source be connected with seepage matter, and the connected mode that guarantees the interface sealing has a lot, and this is soluble according to existing public technology for general technical staff.One of connected mode that it is concrete can be appropriate location punching on water-supply-pipe or aqua storage tank, then seepage matter is put sealing ring and directly inserts eyelet on water-supply-pipe or the aqua storage tank, and is both simple and practical, again convenient and swift.Also have a kind of simple and practical method to be, seepage matter is inserted eyelet on water-supply-pipe or the aqua storage tank, coat then water-fast sealant sealing.If seepage matter adopts geotextiles, this can wrap up geotextiles with corrosion resistant elastomeric material, inserts together then the eyelet on water-supply-pipe or the aqua storage tank.Preferred mode is simultaneously at the elastomeric material of package action (such as plastics etc.) inwall projection to be set, and is used for the extruding geotextiles, plays the effect of control geotextiles water yield.
Above-mentioned anti-blocking automatic filtration irrigation method, the selection of its seepage matter can be carried out design and installation according to different plants and growing environment and use function etc. with arranging, and this can accomplish for a person skilled in the art.For example afforest in desert area, because extreme lack of water, and moisture evaporation and seepage are exceedingly fast, seepage matter is the suitable fictile that uses just, operated by rotary motion is in the place near plant root, and the space between plant can arrange, 24 hours maintenance water-filling states in the aqueduct, the capillary water seepage function that has by seepage matter docks the lasting uniformly water supply of formation with soil capillary, efficiency of water application is high.If plant smooth lawn, then suit to select geotextiles as seepage matter, soil around can fast, uniformly water being sent into like this, so that the lawn can obtain relatively uniformly output around the infiltration point, to reach the uniformity of the whole growth result in lawn, time and the water yield of irrigating then can be achieved by the water source is controlled.If need to carry the bigger water yield, water percolating capacity that can also be by increasing single seepage matter or increase seepage matter density regulate.The water percolating capacity of single seepage matter can be by increasing the contact area of seepage matter in water and the dynamics of seepage matter extruding etc. being controlled.
Beneficial effect of the present invention:
1, adopt filtration irrigation method of the present invention, draw materials easily, processing and install simply invest littlely, and cost is low, easy marketing.
2, the present invention be by seepage matter to the soil water delivery, changed and traditional passed through pipeline or ooze the hole of head to the mode of soil water delivery, therefore can silting, solved the difficult problem that always can't overcome in the prior art; Because whole facility is simple, seepage matter is changed easily, keeps in repair also very convenient.
3, the present invention passes through two class seepage matters to the soil water delivery.One class is the object that can form capillarity, such as fictile; Another kind of is the object that can form siphonage and have the anti-filter function, such as geotextiles.The former water yield is even unusually, stable, not influenced by the water source; Though the latter's water yield is subjected to the pressure influence at water source, easy Artificial Control, and water outlet is equally more uniform and stable, is beneficial to the g and D of crop.
4, adopt filtration irrigation method of the present invention, can be as required near the infiltration of infiltration thing is set near the plant roots, not only save the water yield greatly, and weed growth that can the controlling plant gap.
In a word, use anti-blocking automatic filtration irrigation method of the present invention, draw materials easily, processing and install is simply invested littlely, compared with prior art, does not produce the silting phenomenon, has solved the difficult problem that this technical field can't overcome always.And the present invention by seepage matter to the plant root soil water delivery so that water yield is uniform and stable, easily control, also more water saving is beneficial to the g and D of plant.
