A kind of water cable subirrigation system, its composition comprises: irrigate main-supply and water cable, opened one group of water supply hole on the described main-supply, described main-supply and water cable are communicated with in the water supply hole position, and both are fixed and seal at this, with described another end sealer of water cable, described water cable is mated formation in underground 10～25 centimetres of degree of depth in plant plantation farmland according to ridge length.
Described water cable subirrigation system, described water cable adopt connector to carry out spreading along its length and handle.
A kind of method of utilizing the water cable to irrigate, comprise: main-supply curb farmland one side is installed, according to a ridge or every mode perforate on the main-supply road on ridge, described water cable one end is installed on the water supply hole and along the trend on ridge mats formation in underground 10-25 centimetre depths, form subirrigation system, described feed pipe is transported to water in the water cable, driving the water cable by soil water potential energy and provide continual moisturizing to soil and plant, is a kind ofly not need the machine power method of driving irrigating running.
The described method of utilizing the water cable to irrigate, water cable adopt bionical pervious function pellicle to make, and form and do not produce the water-saving irrigation mode of runoff and filter loss, have avoided most of evaporation loss; Pellicle discharges the absorption water behavior of the behavior match plant root pellicle of water in the water cable, and causes the fluctuation of soil water potential to be fluctuateed with the fluctuation of different period plant water consumption, and plant is carried out continual continuous irrigation.
Effect of the present invention:
Core of the present invention is that the pellicle function of material and the absorbent function of crop root part are appropriately mated, irrigation process and water absorption course carry out synchronously, avoid or reduced evaporation loss and filter loss in the irrigation process significantly, for agricultural production provides a kind of very irrigation method of water saving.
The cell membrane of plant root is a pellicle, plant depends on the infiltration function of these cell membranes, under the driving of potential energy, absorb moisture from soil, when the flow of water in the root cells is lower than soil water potential, moisture is under water potential energy drives, and to the migration of potential energy lower, promptly soil moisture is passed through the cell pellicle and moved in cell by the potential energy eminence, make plant absorbing arrive enough moisture, keep normal growth; But when arid took place, soil moisture content reduced, and soil water potential reduces gradually, when the flow of water is lower in being reduced to than root cells, at this moment intracellular moisture is in the high potential energy attitude, and plant not only can not absorb water from soil again, and is opposite, intracellular moisture is under the flow of water drives, pass through pellicle and in soil, move, the plant dehydration, turgescence descends, wilt, growth course is rented.If at this moment bury a water cable at the plant root of suffering from drought, because the water cable is made with the plastics pellicle, the Free water flow of water of water cable inside is zero, be in the high state of the flow of water, the flow of water that is higher than the outer dry soil of water cable, moisture passes through water cable pellicle and moves to soil, causes soil moisture content to increase gradually, and the flow of water rises gradually.When soil water potential rises to when higher than the plant roots flow of water, according to preceding described, soil moisture begins again to make plant absorbing moisture to plant migration, is irrigated.
As seen, because the use of water cable,---soil---plant has formed the dynamical system of a water translocation at the water cable, the water of water cable inside is in the highest flow of water state all the time, the dry soil flow of water is lower, under flow of water difference drives, moisture is by striding the film migration, the pellicle that water in the water cable passes self moves in soil, and soil moisture is increased, and the flow of water is increased on the higher level, the root flow of water that is higher than plant, the flow of water difference of the two causes another time to stride the film migration again, makes moisture see through the plant root pellicle to plant migration, and plant is irrigated.From another perspective, when the moisture in the plant through the blade face during rising the dissipation, the flow of water descends, plant and soil water potential difference strengthen, causing moisture is the migration amount increase of unit interval from soil to the migration velocity of plant, and then causing soil water potential to reduce, the flow of water difference of soil water potential and water cable strengthens, and impels more water to move to the interior from the water cable and shifts to soil.As seen, the dynamic interaction relation of moisture between the three produced such result, and promptly the plant water consumption is many more, and the water cable supplies water many more, and the plant water consumption is few more, the also corresponding minimizing of water cable water supply.This best that is field irrigation is pursued is irrigated state.
Why the water cable can make farmland moisture be in optimum state if being irrigated, be because water cable irrigation water supply principle is by the pellicle feedwater, and plant is by the pellicle suction, is isomorphisms at two kinds of films aspect the water shift function.Aspect power mechanism, they are tended to act by the flow of water again by same rule, and when they constituted same system, water cable inner membrance can be realized supplying water according to the rhythm of biomembrane suction and number change.Therefore, it is a bionical irrigation system that the water cable is irrigated, and is characterized in:
1, very water saving
Because the irrigation process of water cable is driven by flow of water difference, soil is dry more, flow of water difference is big more, the water cable supplies water many more, vice versa, when soil moisture content reaches full when closing water content, soil water potential rises to zero, with the flow of water difference of water in the water cable be zero, the water cable stops to supply water, so the irrigation of water cable can not cause runoff loss or filter loss.In addition, the water cable is to be embedded in the main root district floor at below ground 10～25cm place when using, and the face of land is one deck dry ground layer, and the interior moisture of dry ground layer protection its underpart wetting layer is avoided evaporation loss, makes that evaporation loss reduces significantly in the irrigation process.In a word, because the irrigation of water cable is avoided or alleviated three kinds of main moisture loss modes of common field irrigation, make this system become a kind of very effective irrigation method of water saving.Application experiment shows, is subjected under the sufficient preceding topic of irrigating crop, and the water consumption that the water cable is irrigated is 10～20% of the average at present mu water consumption of China, i.e. water saving reaches 80～90%, is a kind of very irrigation method of water saving.
2, consumption of power not
The water cable irrigation system structure is very simple, only form by water tank, pipeline, water cable three parts, do not contain mechanical and power equipments such as water pump, not consumption of power in service, these characteristics have been saved the energy on the one hand, reduced operating cost, making does not on the other hand have the remote districts of power supply can conveniently use yet.
3, irrigate continuously
The process of any plant absorbing moisture all is 24 hours continual continuous process.And prolong till the present, adopt irrigation method in the agricultural production, no matter be canal irrigation, sprinkling irrigation, drip irrigation, infiltrating irrigation, be batch (-type) is irrigated without exception all.In the watering period that batch (-type) is irrigated, only some period can fully be satisfied the demand of plant suction, all the other periods then right and wrong fully satisfy or moisture association compels the period, make the growth of plant be subjected in various degree inhibition and influence.
The water supply process that the water cable is irrigated is 24 hours continual continuous process, and is synchronous with the water absorption course of plant, makes any time of plant in growth period all be subjected to abundant irrigation, is not subjected to periodicity moisture association to compel to influence, and helps the high yield good harvest of crop,
