As preferably, if water storage is not enough in cistern body, for supply, supply water, spy has increased a set of water charging system, and described cistern body inner bottom part has a pressure sensor, the external controller being provided with on a running water pipe and running water pipe of cistern; Hydraulic pressure in pressure sensor monitoring cistern body is controlled the switching of running water pipe water outlet, keeps the enough moisture storage capacitys of cistern.
As preferably, too much in order to prevent irrigation water impurity, blocking pipe, is also provided with centrifugal filter between described drainpipe and water pump.
As preferably, for the effect of further increasing water quality, reduce impurity, sandrock filter is also installed between described centrifugal filter and water pump.
As preferably, in order more high efficiencyly to utilize the water in cistern body, described drainpipe is to cistern body inside to downward-extension.
As preferably, in order to realize tentatively, the water in cistern body is filtered, the mouth of pipe of described drainpipe is provided with well strainer.
As preferably, because geotextiles has outstanding filtration, draining, isolation, reinforcement, antiseepage, protective action, have lightweight, tensile strength is high, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, corrosion-resistant, described dank material film is made by geotextiles.
As preferably, for better draining infiltrating irrigation, on described dank material film, there is water hole.
Beneficial effect: the present invention in terms of existing technologies, for shallow root system crop, can realize farmland underground water level and discharge unnecessary underground water when higher, be stored in tank, when subterranean water level is lower, still by former drainpipe, carry out infiltrating irrigation while affecting plant growth, realize draining and the irrigation dual-purpose function of underground piping, thereby contributed to the efficient utilization of water resource, contributed to the stable high yield of crop.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1 to Figure 3, a kind of irrigation and drainage integrated apparatus, comprises one group of subsurface irrigation pipeline 2, underground water conduit 1, cistern body 10, water inlet pipe 7, drainpipe 8, water pump 14 and two autocontrol valve; One end of described one group of subsurface irrigation pipeline 2 is connected with underground water conduit 1 respectively; The other end of subsurface irrigation pipeline 2 is opening-like, and dank material film 3 is installed; Described underground water conduit 1 is connected with water inlet pipe 7, and water inlet pipe 7 is connected with cistern body 10, and described the first autocontrol valve 12 is arranged on water inlet pipe 7; One end of described drainpipe 8 is connected with a side of water inlet pipe 7, and the other end of drainpipe 8 is connected with cistern body 10, and described water pump 14 and the second autocontrol valve 13 are arranged on respectively on drainpipe 8.
In the present invention, whole irrigation and drainage integrated apparatus is arranged in underground 0.3 ~ 0.6m, when rainy season, subterranean water level was higher, the first autocontrol valve 12 is opened, the second autocontrol valve 13 is closed, and 3 water suctions of dank material film, enter cistern body 10 by underground water conduit 1 by underground water; When subterranean water level is lower, in the time of need to irrigating, the second autocontrol valve 13 is opened, and the first autocontrol valve 12 is closed, and water pump 14 draws water, and the water of the storage in cistern body 10 is seen through to dank material film 3 by subsurface irrigation pipeline 2 and carry out infiltrating irrigation.
If the interior water storage of cistern body 6 is not enough, for supply, supply water, spy has increased a set of water charging system, and described cistern body inner bottom part has a pressure sensor 6, and the controller 4 on a running water pipe 5 and running water pipe is installed outside cistern body 10; Hydraulic pressure in pressure sensor 6 monitoring cistern bodies 10 is controlled the switching of running water pipe 5 water outlets, keeps cistern body 10 enough moisture storage capacitys; Too much in order to prevent water quality sandstone, blocking pipe, is also provided with centrifugal filter 15 between described drainpipe 8 and water pump 14; For the effect of further increasing water quality, reduce sandstone, between described centrifugal filter 15 and water pump 14, gravel filter 11 is also installed; In order more high efficiencyly to utilize the water in cistern body 10, described drainpipe 8 is to cistern body 10 inside to downward-extension; In order to realize tentatively, the water quality in cistern body 10 is filtered, the mouth of pipe of described drainpipe 8 is provided with granular membrane 9.Because geotextiles has outstanding filtration, draining, isolation, reinforcement, antiseepage, protective action, have lightweight, tensile strength is high, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, corrosion-resistant, described dank material film 3 is made by geotextiles; For better draining infiltrating irrigation, on described dank material film 3, there is water hole 16.
When not opening irrigation switch, the first autocontrol valve 12 is in opening, and the second autocontrol valve 13 is in closed condition, and when subterranean water level is higher, geotextiles water suction enters cistern body 10 by underground water from water-supply-pipe 7 by underground water-supply-pipe 2.When subterranean water level too low, in the time of need to irrigating, open irrigation switch, now the first autocontrol valve 12 is closed automatically, the second autocontrol valve 13 is opened automatically, and water pump 14 is extracted underground discharge water out from cistern body 10, filters after sandstone impurity successively respectively by granular membrane 9, centrifugal filter 15 and gravel filter 11, continuation is water suction subsurface irrigation pipeline 1, makes water see through geotextiles and infiltrating irrigation is carried out in water hole 15.When pumping irrigation, if the interior rain water storage quantity not sufficient of cistern body 10, the water yield is lower than a certain water level value, by pressure sensor 6, cistern 10 base pressures detected when lower, emissioning controling signal " 1 " is given running water pipe controller 4, thereby open running water water pipe 5, to cistern body 10, supply water, when the water yield reaches a certain setting higher level, by pressure sensor 6, cistern body 10 base pressures detected when higher, emissioning controling signal " 0 " is given running water pipe controller 4, thereby close running water water pipe 5, stop discharging water, to keep there are enough moisture storage capacitys in cistern body.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
