Embodiment
The exemplary embodiment of the present invention is more fully described below with reference to accompanying drawings.Although the present invention is shown in accompanying drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
Limited.Conversely, there is provided these embodiments are to be able to be best understood from the present invention, and can be by the scope of the present invention
Completely it is communicated to those skilled in the art.
Water circulation system of the embodiment of the present invention and method are described in detail below in conjunction with the accompanying drawings.
Embodiment one
Fig. 1 is the structural representation of water circulation system one embodiment provided by the invention.As shown in figure 1, the present invention is real
Applying the water circulation of example specifically may include：Above each layer planting groove 1, water or nutrition are injected into planting groove 1 for periodicity
The water inlet 2 of liquid；It is arranged in planting groove 1, a delivery port 3 of restricting water supply for the water level for limiting the reclaimed water of planting groove 1 or nutrient solution；
The bottom of planting groove 1 is arranged at, for emptying the discharge outlet 4 of water or nutrient solution in planting groove 1；Water inlet 2, a water outlet of restricting water supply
Mouth 3 and discharge outlet 4 are arranged to meet following relation：The restrict water supply water of a delivery port 3 or the body of nutrient solution are flowed through in unit interval
Product, which was more than in the unit interval, flows through the water of water inlet 2 or the volume of nutrient solution；Water or the nutrition of water inlet 2 are flowed through in unit interval
The volume that the volume of liquid is more than water or nutrient solution that discharge outlet 4 is flowed through in the unit interval (illustrate only one layer of planting groove in Fig. 1
Structural representation).
Specifically, side view as shown in Figure 1, the direction of arrow in Fig. 1 represents the flow direction of water or nutrient solution, water
Or nutrient solution is injected into planting groove 1 via the water inlet 2 of the top of planting groove 1, because upper water speed (flows through in the unit interval
The water of water inlet 2 or the volume of nutrient solution)>Drainage speed (flows through the water of discharge outlet 4 or the body of nutrient solution in the unit interval
Product), thus the water or nutrient solution injected by water inlet 2 only have part flowed out via discharge outlet 4, now the water in planting groove 1 or
The water level of nutrient solution is gradually started from scratch rising.When the water in planting groove 1 or the water level of nutrient solution are higher than a delivery port 3 of restricting water supply
During height, water or nutrient solution in planting groove 1 can also flow out via a delivery port 3 of restricting water supply, due to lower water speed (i.e. unit when
It is interior to flow through the restrict water supply water of a delivery port 3 or the volume of nutrient solution)>Upper water speed (flows through the water of water inlet 2 in the unit interval
Or the volume of nutrient solution), therefore the now water level (i.e. peak level) of the water in planting groove 1 or nutrient solution and a delivery port of restricting water supply
3 height keeps equal.After water inlet 2 stops injecting water or nutrient solution into planting groove 1, water or nutrition in planting groove 1
Liquid flows out via discharge outlet 4, until the water or nutrient solution in planting groove 1 all empty.
This periodicity water feeding mode so that the water level of water or nutrient solution in planting groove 1 is periodically raised to most from above freezing
High water level, then drop to zero from peak level, i.e. the root of plant is periodically soaked in water or nutrient solution or exposed to air
In, while plant nutrient and moisture absorption is ensured, the oxygen absorbed of plant root is added, so that the more conducively life of plant
It is long.
Further, the position in the corresponding planting groove 1 of water inlet 2 and the position for a delivery port 3 of restricting water supply should try one's best be spaced compared with
Far, such as respectively positioned at two of planting groove 1 it is diagonal near, to strengthen the water circulation effect in planting groove 1 so that planting groove 1
In water or nutrient solution be more evenly distributed.
Further, the position in the corresponding planting groove 1 of water inlet 2 and the position of discharge outlet 4 should try one's best interval farther out, and arrange
The position at the mouth of a river 4 and the position for a delivery port 3 of restricting water supply also are spaced farther out as far as possible, such as respectively positioned at the two of the both ends of planting groove 1
Near individual adjacent angle, to strengthen the water circulation effect in planting groove 1 so that water or nutrient solution in planting groove 1 are more evenly distributed.
Further, the root for guarantee plant can all be immersed in water or nutrient solution and fully absorb water and nutrition
Liquid, during upper water, the water level of water or nutrient solution in planting groove 1 should be able to reach peak level and preferably be maintained at peak level
For a period of time.To reach this purpose, following two control modes can be used：The first, because planting groove 1 fills water or nutrition
The time of liquid (i.e. water level reaches the height i.e. peak level of a delivery port of restricting water supply from zero) is fixed, therefore can control water inlet 2
The upper water time is equal to or more than planting groove 1 and fills time of water or nutrient solution, i.e., water inlet 2 injected into planting groove 1 water or
The duration of nutrient solution, a delivery port 3 of restricting water supply is reached from zero equal to or more than the water in planting groove 1 or the water level of nutrient solution
The highly desirable time.Second, the water level of the water or nutrient solution in planting groove 1 is detected, when the water level in planting groove 1 reaches
Restrict water supply a delivery port height when, water inlet 2 stops upper water or continued for some time to stop upper water again immediately, i.e., water inlet 2 is vertical
Even after waiting setting time, stop injecting water or nutrient solution into planting groove 1.
Further, the root for guarantee plant can all expose in atmosphere and fully absorb oxygen, water in stopping
When, the water level of water or nutrient solution in planting groove 1 should be able to drop to zero and preferably be maintained at for zero a period of time.To reach this
Purpose, following two control modes can be used：The first, due to the emptied of water of planting groove 1 or nutrient solution, (i.e. water level is from position of restricting water supply
The height of delivery port is to fix zero) time that peak level drops to, therefore the stopping of the water inlet 2 upper water time can be controlled to be equal to
Or more than the emptied of water of planting groove 1 or the time of nutrient solution, i.e., water inlet 2 stops injecting water or nutrient solution into planting groove 1
Duration, reached equal to or more than the water in planting groove 1 or the water level of nutrient solution from the height equal to a delivery port 3 of restricting water supply
Zero time needed.Second, the water level of the water or nutrient solution in planting groove 1 is detected, when the water level decreasing in planting groove 1 to zero
When, water inlet 2 immediately begins to water or continued for some time start upper water again, i.e., water inlet 2 immediately or wait setting time after,
Start to inject water or nutrient solution into planting groove 1.
The water circulation system of the embodiment of the present invention, water inlet periodically injects water or nutrient solution into planting groove, and flows through
The speed of a delivery port of restricting water supply is more than and flows through the speed of water inlet, and the speed for flowing through water inlet is more than the speed for flowing through discharge outlet,
So that the water level of the water or nutrient solution in planting groove is periodically raised to peak level from above freezing, then drop to zero from peak level,
I.e. the root of plant is periodically soaked in water or nutrient solution or in air, is ensureing plant nutrient and moisture absorption
Meanwhile the oxygen absorbed of plant root is added, so that the more conducively growth of plant.
