Abstract
An improved irrigation method features that the filler made of fiberous, reticular, or granular substance, such as sponge, chemical fibres, hydroscopic resin, or plant fibres, is uniformly filled in the pipeline which has been buried underground for osmotic irrigation for slowly releasing water.
Description
The present invention relates to a kind of irrigation method and irrigation conduit structure, belong to agricultural irrigation technology, is the improvement to conventional infiltrating irrigation, drip irrigation method.Agricultural accounts for 70% of whole fresh water demands with fresh water in the human according to estimates water, and therefore, the saving of agricultural water and the raising of efficient are significant to the reasonable utilization of global freshwater resources.Except the irrigation method of traditional employing open drain, canal formula, the existing plant method of supplying water of more effectively giving is sprinkling irrigation or drip irrigation, but this method supply water can be by only accounting for about 10% that plant root absorbs, and the high maintenance cost of its construction cost is big.In order further to improve the availability of water resource, proposed advanced to utilize method (is described in 00105783 as number of patent application) that super absorbent resin (solid water) feeds water to plant and the method that the provided underground soakaway trench drips, infiltrating irrigation is fed water (as number of patent application 99125199,00226433, described in 00242297,00126516).
The above-mentioned shortcoming of advanced water feeding method is that water-absorbing resin directly contacts with earth, reduced regeneration of resin service life, and pure ground or underground, the pipeline that oozes in the water feeding method use mainly as aqueduct, promptly only play effect (but the water free-flow in water pipe of common water pipe, therefore the water capacity easily runs off), do not have the effectively long-time function that stores water (described be meant that for a long time stored water can be stored in the pipeline in non-free-flow mode).
The purpose of irrigation method of the present invention is to gather the advantage of technology formerly, and overcomes the shortcoming of technology formerly.Its embodiment is thread, the netted or particulate material that will adsorb or absorb water, and as sponge, chemical fibre, water-absorbing resin, vegetable fiber etc., inserts equably as the filling material and to be used to be embedded in the pipeline of subsurface irrigation.Consider the expansion of absorption of filling material or suction back volume, the filling material need not be full of whole pipe (as shown in Figure 1), but preferably can be full of the entire cross section of pipeline after the filling material fully absorbs water.When the filling material after using loss to some extent for a long time, can new filling material be advanced in the pipeline by the promotion of pressure.Having little infiltration hole or slit on the described pipeline (uses when underground best aperture of opening or slit above pipeline, the hole is blocked by earth in order to prevent to seep water, pipeline is outer can be placed with anti-blocking layer), the water that allows to store in the pipeline slowly discharges in the earth that infiltrates the pipeline top and does not permeate the ground easily.For strengthening the intensity of pipeline load capacity, also can put into network structure in the pipeline with certain intensity, absorption or absorbent material were filled in the structure of network and were positioned this moment, made the filling material be difficult for moving in pipeline.
Appended view is illustrated the interior of described pipeline.
Fig. 1 is the cross sectional representation that is filled with absorption or absorbent material in the pipeline.Fig. 2 be pipeline when being embedded in underground use an end have the structural representation that stops silt to enter.Among the figure: 1. pipe wall, 2. tube wall opening or slit, 3. filling material, 4. entrance, 5. landscape position.
Irrigation method of the present invention is that the above-mentioned pipeline that is filled with absorption or absorbent material is embedded in (or installing on the ground) under the field equably with network-like or parallel arrangement mode, can be made into 20 centimetres as pipe diameter, be embedded in underground 30 centimeters, but the inlet of water is left in one or both ends, allows rainwater or irrigation water to enter pipeline from the inlet of water.The porch of water is provided with material or the structure (as shown in Figure 2) that stops silt to enter.
The advantage of irrigation method of the present invention is that absorption or absorbent material are subjected to the protection of pipeline, can be not and earth Directly contact; In addition, be embedded in underground pipeline and not only can be used as aqueduct and use, can also play when long Between the effect of storing up, preserving rainwater or storage, storage irrigation water or replenishing water soluble fertilizer to plant. Therefore can with Rainwater or irrigation water are stored in the underground of field, avoid the evaporation loss of moisture, with balance rainy season and dry season plant water sources Needs. When taking place, damage caused by waterlogging can also utilize the piping network under the field to carry out draining to the field.
Pipeline with long-time storage water function of the present invention should ooze little during as ground droping irrigating pipe Open below pipeline in the water hole, and the water of storing in the pipeline is splashed in the earth under the pipeline lentamente.
