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 soil gradually.
(3) sprinkling irrigation, drip irrigation method are the Novel irrigation modes 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, then is ejected in the air through shower nozzle, 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, infiltrates the root soil of crop.
(4) infiltrating irrigation refers to by related facility with water directly sending into below 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 advantages 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 on the land for growing field crops and roughly can be divided at present two kinds of point type and line formulas, point type (claiming again outlet type) is exactly with fluid-tight plastic tube, water to be delivered to plant root, then irrigates by a kind of head that oozes that is embedded in underground slowly water seepage.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 tube wall.Will ooze out as perspiration gradually during water-filling in pipe, irrigate.In recent years report that more a kind of infiltrating irrigation pipe is after utilizing the admixtures such as crumb rubber end, PVC molding powder and blowing agent to mix, through the soakaway trench that has a large amount of micropores on tube wall of the 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 out moistening its surrounding soil of seepage flow by pressure as perspiring.Want like this setting pressure device at the water source; Because the infiltrating irrigation micropore is relatively poor for the permeability of air, need to settle exhaust apparatus at the infiltrating irrigation pipe afterbody simultaneously.
With regard to adopting above-mentioned this hole infiltrating irrigation to carry out plant filtration irrigation, also there are some following problems, to such an extent as to be difficult to spread:
1, whole system is complicated, comprises that every facility costs such as exhaust apparatus of pressure apparatus, infiltrating irrigation pipe afterbody at water source are high, and in case stop up, clean, maintenance and management all very difficult, therefore not only use cost is too high, and and inconvenience.
2, adopt this irrigation method, although 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, due to whole pipeline all in infiltration, not only cause water resource waste, and remain moistening easy growth of weeds in the plant gap.
4, the silt in soil easily stops up the micropore of soakaway trench, 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 present infiltration irrigation technology are large, 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 takes is as follows:
A kind of anti-blocking automatic filtration irrigation method, the method be by with the contacted seepage matter in water source to the plant root soil water delivery, said water source comprises whole water delivery or the water storage system of water delivery source, water delivery or water storage facility, and said seepage matter refers to fictile or geotextiles; The appropriate location punching, then be installed on seepage matter the eyelet on water-supply-pipe or aqua storage tank on the water-supply-pipe of water delivery or water storage system or water storage mortise, seeps water to soil by seepage matter; When seepage matter is installed, seepage matter is put sealing ring directly insert eyelet on water-supply-pipe or aqua storage tank, coat water-fast sealant sealing after perhaps seepage matter being inserted the eyelet on water-supply-pipe or aqua storage tank; When seepage matter adopts geotextiles, with corrosion resistant elastomeric material, geotextiles is wrapped up, then insert together the water-supply-pipe of water delivery or water storage system or the eyelet on aqua storage tank.
Above-mentioned anti-blocking automatic filtration irrigation method, described water source refer to and can provide water to seepage matter, namely can make a termination of seepage matter contact water.It comprises whole water delivery or the water storage system of 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. be can build, pond nearby, ditch that surface water forms etc. even 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 then fire to form 1000-1100 ℃ of left and right 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 extremely 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 front a kind of fast by siphonage for rear a kind of seepage matter, and can be subject to the impact of hydraulic pressure.
No matter use which kind of seepage matter, water can only be exported and can not spill from the interface of seepage matter and other device by seepage matter, 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 aqua storage tank, and is both simple and practical, convenient and swift again.Also have a kind of simple and practical method to be, seepage matter is inserted eyelet on water-supply-pipe or aqua storage tank, then coat water-fast sealant sealing.If seepage matter adopts geotextiles, this can wrap up geotextiles with corrosion resistant elastomeric material, then inserts together the eyelet on water-supply-pipe or aqua storage tank.Preferred mode is simultaneously on the elastomeric material of package action (as plastics etc.) inwall, projection to be set, and is used for the extruding geotextiles, plays the effect of controlling the geotextiles water yield.
Above-mentioned anti-blocking automatic filtration irrigation method, the selection of its seepage matter and setting can be carried out design and installation according to different plants and growing environment and use function etc., and this can accomplish for a person skilled in the art.For example afforest in desert area, due to the extreme lack of water, and moisture evaporation and seepage are exceedingly fast, seepage matter is with regard to suitable use fictile, 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 aqueduct, the capillary water seepage function that has by seepage matter docks the lasting water supply uniformly of formation with soil capillary, efficiency of water application is high.If plant smooth lawn, the suitable geotextiles of selecting is as seepage matter, soil around can fast, uniformly water being sent into like this, so that around the infiltration point, the lawn can obtain more uniform output, to reach the uniformity of the whole growth result in lawn, time and the water yield of irrigating can be achieved by the water source is controlled.If need to carry the larger 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 easily changed, and 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, as fictile; Another kind of is the object that can form siphonage and have the anti-filter function, as geotextiles.The former water yield is extremely even, stable, not affected 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.
