The water supply tank the injecting process is following: close the water supply tank flowing water Valve, open the water supply tank Water filling valve, inject irrigation water from the water supply tank water filling port, till irrigation water overflows from the upper edge, top of water supply tank water filling port, close the water supply tank Water filling valve, finish the injecting process.
Irrigator water-filling and automatic irrigation process are following: open the water supply tank flowing water Valve, the irrigation water in the water supply tank flows into water level control pond through the water supply tank flowing water Valve of opening, and from the lower port air inlet of water supply tank air inlet pipe, the process that makes irrigation advance go into water level control pond is able to continue; The water level in water level control pond is raised gradually, and irrigation water gets into the bottom intake tunnel in the U type groove groove of several irrigators that communicate with it through the delivery main collecting pipe, before U type groove behind water fender and the U type groove under the stopping of water fender, and the irrigation water that water level continues to raise; Through permeable cover plate and sandstone loaded filter, get into the zone of banketing of U type groove groove internal upper part, the water level when water level control pond surpasses h1, and the lower port of water supply tank air inlet pipe is submerged; The lower port of water supply tank air inlet pipe changes into water into by air inlet, water level in the water supply tank air inlet pipe and the grade of the water level in water supply tank height, and the lower port water inlet of water supply tank air inlet pipe stops, and the irrigation water in the water supply tank also stops to flow into water level control pond; The stable level in water level control pond in the zone of banketing of U type groove groove internal upper part, has formed the soil saturation water layer of controlling height such as pool water level grade with water level, because of the suitable cell wall upper edge height h2 that has been lower than U type groove of h1 on the water level a little more than h1; The gravitational water of soil saturation water layer is bound in the groove of U type groove, can not produce the gravitational water seepage loss, under soil capillarity, and the water of soil saturation water layer in the U type groove groove; With the form of capillary water, rise to the crop root layer, a spot of water of depolarization can continue to rise to outside the evaporation of soil table, the water of the overwhelming majority; After arriving the crop root layer, because the effect of the water potential energy difference of soil, plant, atmosphere finally is delivered in the atmosphere with the rising form of crop plant, the crop plant transpiration has consumed the water of the soil saturation water layer in the U type groove groove; Soil saturation water layer height in the U type groove groove is descended, and the water level in water level control pond also descends thereupon, when water level is lower than h1, the lower port of water supply tank air inlet pipe is surfaced; Beginning is with the form air inlet of bubble, and the irrigation water in the water supply tank begins to flow into water level control pond again, and the water level in water level control pond raises, and floods the lower port of water supply tank air inlet pipe again; Air inlet stops, and the irrigation water in the water supply tank stops to flow into water level control pond again, and the crop water consumption causes the water level depression in water level control pond, and the lower port of water supply tank air inlet pipe is surfaced; Beginning is with the form air inlet of bubble, and the irrigation water in the water supply tank begins to flow into water level control pond again, and the water level in water level control pond raises, and floods the lower port of water supply tank air inlet pipe again; Air inlet stops, and the irrigation water in the water supply tank stops to flow into water level control pond again, and the crop water consumption causes above-mentioned water supply process ceaselessly to be repeated, in water supply process; The water level in water level control pond fluctuates around h1 a little, and the water level in the water supply tank air inlet pipe together descends with the water level in the water supply tank, if vertical section of water supply tank air inlet pipe is transparent, can directly observe the water level depression degree of intake process and water supply tank; Judge operation whether normal with decision whether to the water supply tank water filling, rainfall will make the soil saturation water layer be higher than h1, the water level in water level control pond also is higher than h1 thereupon, supplying water stops automatically; Be lower than h1 up to the soil saturation water layer, supply water and recover automatically, the crop water consumption causes water supply; Make how much water of material consumption, just supply how much water, output increases and decreases with water consumption; Self adaptation need not human intervention and artificial external energy, has realized irrigation automation cheaply.
The present invention has following good effect:
What common infiltrating irrigation was adopted is that the intermittent water application of pressure mode is arranged, because water is a kind of elastomer, when stopping to supply water, pressure oscillation is violent, is easy to negative pressure occur at apopore, sucks soil particle, causes apopore to stop up.The intermittent water application mode also is the major reason that crop root stops up apopore; Because root system of plant hydrotropism growth characteristics; The back ground moistening scope that stops to supply water is shunk to apopore gradually; Because the existence of soil moisture gradient, root system of plant is also being followed to the apopore extension in order to obtain moisture, finally stops up apopore.And novel nothing of the present invention is pressed irrigation rig, and flowing of water is very slow, and under the effect of loaded filter and non-fine concrete, soil particle can not move, and can not take place to stop up and alluvial.Novel nothing of the present invention is pressed irrigation rig, has the soil saturation water layer, even there is root system to get into the soil saturation water layer, does not lose the direction of growth because of there being the soil moisture gradient, can not pass through the soil saturation water layer and get into loaded filter, and the root system blockage problem takes place.
Common infiltrating irrigation is except physics stops up, and the most unreasonable dissolving salt that surely belongs to is separated out chemistry obstruction and the biological obstruction of bacterium class, does not have good way to solve so far.And novel nothing of the present invention is pressed irrigation rig, and the non-fine concrete porous disc of employing, sandstone loaded filter can not find out dissolving salt and separate out the record that chemistry stops up, bacterium class biology stops up in existing document.According to one's analysis, possible reason is: non-fine concrete, the distinctive hole of sandstone loaded filter are circuitous dendritic stereochemical structure, and moisture can be ganged up after getting into each other, so even most of hole is blocked, still can keep suitable water penetration.Novel nothing of the present invention is pressed irrigation rig; River constructions such as the U-shaped concrete pit that adopts, non-fine concrete porous disc, sandstone loaded filter are commonly used, draw materials easily, and cost is not high; It is convenient to build, and key is that its reliability and durability are confirmed by the long-term practice of river construction.
It all is to utilize the water potential energy difference and the capillarity of soil, plant, atmosphere to irrigate that novel nothing of the present invention presses irrigation rig and negative pressure to irrigate, and is most effective up to now irrigation method.The irrigation process is carried out automatically, need not to carry out the decision-making of irrigation time and irrigation volume, how much water just to supply how much water with.The negative pressure irrigated soil do not have gravitational water, deep percolation can not take place.Novel nothing of the present invention is pressed irrigation rig; Though soil has gravitational water---the soil saturation water layer; But be bound in the U type groove, do not have the deep percolation that common infiltrating irrigation possibly occur and the situation of nutrient loss, the evaporation of soil table is also very limited; The height of WUEL is that any other irrigation method institute is inaccessible.The energy consumption of the water potential energy difference of soil, plant, atmosphere is come to solar radiant energy, energy-saving and environmental protecting.But negative pressure is irrigated and to be implemented very difficulty, the one, the sealing of water-carriage system there is very strict requirement, and can not leak gas, in case under ground portion bad seals is especially searched and keep in repair ten minutes difficult; The 2nd, the gas that under negative pressure condition, is dissolved in the water will be separated out, if untimely processing will produce cutout.Therefore, need regularly exhaust, and exhaust process complicated and trouble very, it is consuming time to require great effort, and has also increased managerial difficulty simultaneously; The 3rd, it is too small that negative pressure irrigator its specific structure (precondition of negative pressure irrigator and soil water exchange is that outer wall energy forms permeable air-locked moisture film) makes it water yield; Ground moistening is limited in scope; Can only be through increasing the method that the negative pressure irrigator is arranged density or increased single negative pressure irrigator water supply face; Improve the moistening uniformity, making to drop into increases, and safeguards difficulty more; The 4th, the negative pressure irrigator is different with the soil texture, and discontinuous, the not of uniform size interface that causes of tangible hole is arranged, and whether unobstructed, also will depend on the tightness degree that the negative pressure irrigator contacts with soil if supplying water, have certain uncertainty.And novel nothing of the present invention is pressed irrigation rig, and atmospheric pressure supplies water down, and the soil saturation water layer in the irrigator and its top soil texture that supplied water is the same; Hole is consistent continuously; Soil capillarity has performed to ultimate attainment, and it is unobstructed to supply water, and feedwater is sufficient; Under the situation of the same moistening uniformity, can reduce the layout density of irrigator.Under ground portion need not additional seal, also need not special exhaust apparatus is set, and is simple to operate, easy to use.
Adopted law of connected vessels because the present invention supplies water, head is consistent, and according to Darcy's law, soil saturation water layer height is also consistent, and the water supply uniformity is very high.Even and common infiltrating irrigation has been installed flow regulating equipment additional and also can't have been reached so high water supply uniformity.
The underground plastic delivery hose of common infiltrating irrigation road suffers damaged by rats easily.And groundwater supply device of the present invention, there is the soil saturation water layer on top as barrier, and bottom and side are concrete, and mouse has no interest, and also gnaws motionless.
