Description

System for plant root irrigation and soil drainage

technical field

The invention relates to a system for plant root system seepage irrigation and soil body drainage.

Background technique

The existing plant watering and irrigation mostly adopts the surface watering method, and the water flow seeps into the roots of the plants from the surface, so that the roots of the plants can replenish water and complete the required water replenishment. Although irrigation technology has been continuously innovated in recent years, various plant irrigation and watering methods such as sprinkler irrigation and drip irrigation have been adopted, as shown in Figures 1 and 2, but the watering and irrigation methods are all surface irrigation.

However, the surface watering method has the following defects:

1. The watering area of sprinkler irrigation and drip irrigation is large, and the water consumption is large;

2. Due to the continuous and rapid infiltration of surface water flow, surface runoff is generated, and a large amount of surface water flow is lost and wasted;

3. Surface watering and irrigation cause a large amount of water to evaporate and dissipate, which cannot achieve water-saving and time-saving effects;

4. Due to the solid topsoil, the surface watering irrigation method makes the water flow infiltrate slowly. In severe cases, the water flow cannot infiltrate to the roots of the plants, causing the roots to fail to absorb water and the plants cannot grow normally;

5. The nutrient solution and liquid fertilizer required by plants also have the defects of large loss and evaporation by surface pouring and irrigation;

6. Existing plant watering methods. After the soil is oversaturated, the excess water flow cannot be effectively collected, discharged and recycled, and the excess water flow soaks the plant root system and cannot be discharged, which will lead to plant rotten roots, poor growth, and even plant death;

7. Both sprinkler irrigation and drip irrigation are carried out on the ground surface. Due to the photosynthetic reaction, sun and rain, and the influence of hot and cold temperature changes, moss or moss will grow in the nozzle holes and drip holes, which will block the nozzles and drip irrigation outlet holes, causing watering problems. The device is blocked and fails or the irrigation device is aged and damaged.

Contents of the invention

The object of the present invention is to provide a system for infiltration irrigation of plant roots and drainage of soil body, so as to solve the problems of wasting water resources and poor irrigation effect in the existing irrigation methods.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

A system for plant root infiltration irrigation and soil drainage, including a water collection pipe, and a drainage belt arranged on the water collection pipe for leading water into or out of the water collection pipe; the two ends of the water collection pipe are respectively provided with water inlet A valve and a drainage control valve; the drainage belt is a belt-shaped member or a plate-shaped member, and at least one side thereof is provided with a groove for drainage; the drainage belt is located under the ground.

Further, at least one side of the drainage belt has a plurality of small-diameter collection and drainage grooves arranged at intervals along the belt width direction and extending along the entire length of the belt length direction. The narrow gaps of capillary action.

In addition, the present invention also includes an irrigation water reservoir connected to one end of the water collection pipe; the end of the irrigation water reservoir connected to the water collection pipe is the end provided with a water inlet valve.

Further, a water pressure control regulating pool communicated with the irrigation water storage tank and the water inlet valve is also provided.

In addition, the present invention also includes a water flow collection pool connected to the other end of the water collection pipe; the end of the water flow collection pool connected to the water collection pipe is the end provided with a drainage control valve.

Still further, a circulating water delivery pipe communicating with both of the irrigation water storage tank and the water flow collection tank is provided, and a water pump is also provided on the circulating water delivery pipe.

Furthermore, a water quality filter is also provided between the irrigation water storage tank and the water pressure control adjustment tank.

As a preference, a water flow control valve is further provided between the water quality filter and the water pressure control regulating tank.

In order to make the soil and plant root system breathable and transparent, the water collecting pipe is also provided with a vertical air pipe with one end connected to it and the other end located on the ground surface.

In addition, the water collecting pipe is also provided with a nutrient solution and a liquid pesticide supply storage tank connected thereto.

The basic principle of plant root seepage irrigation in the present invention is: when the water collection pipe is filled with water or nutrient solution, liquid pesticide, the water in the water collection pipe will be collected by the drainage belt installed on the water collection pipe in the groove made on the surface of the drainage belt Inside and out of the water collection pipe, the water flow is introduced into the soil through the self-flow of water flow, the osmotic pressure between the water collection pipe and the soil, and the capillary force of the soil and plant roots, so that the plant roots and soil can achieve water supply and complete the purpose of plant root system infiltration irrigation. Since the plant infiltration irrigation method is to directly infiltrate water, nutrient solution, and liquid pesticides into the root of the plant or the soil around the root, it is characterized by avoiding the water consumption of surface runoff, water evaporation, and water flow down in the traditional surface soil watering method. Slow infiltration, large irrigation area, large water consumption, long irrigation time and other defects. Save more than 70% of irrigation water, saving water and energy.

The basic principle of drainage in the present invention is: when there is a large amount of water flow in the atmospheric rainfall or the soil body, and the soil is in a supersaturated state, the plant root system will be filled with water to soak in the surroundings, resulting in hypoxia and root rot diseases in the plant root system. At this time, it is necessary to eliminate excess water flow around the root system to ensure that the soil around the plant root system is in a saturated state, which is conducive to the good growth of plants. The specific steps are to stop injecting water into the water collection pipe, and use the drainage belt to suck the supersaturated water in the soil into the surface of the drainage belt. Open the capillary groove and guide it into the water collection pipe, and discharge the excess water through the water collection pipe.

The working principle of the ventilation function of the plant root system and the soil body of the present invention: when the seepage irrigation is stopped, in order to make a certain porosity between the soil body and the plant root system air-permeable, the drainage control valve is opened and the water flow control valve is closed. At this time, because the ventilation pipe is vertically installed on the water collection pipe, and because of the physical phenomenon of pressure difference between the upper and lower layers of the soil, the external air enters the water collection pipe through the water outlet hole, and the slotted holes on the surface of the soil and the drainage belt communicate with the water collection pipe, forming It provides a channel for the external air to communicate with the soil and plant roots for convection, circulation, and ventilation, and completes the ventilation function of the system.

It is worth noting that although all the components shown in the figures of the present invention are located under the ground surface, the present invention does not limit that all equipment is located under the ground surface, and can also be located on the ground surface, such as: water inlet valves and drainage control valves can be set On the surface, it only needs to be installed on the surface where the two ends of the water collecting pipe are located on the surface. Of course, grooves can also be opened near the two ends of the water collecting pipe, and then corresponding valves can be installed to facilitate control; however, if it is installed under the surface It is still able to realize the corresponding function.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

(1) The present invention irrigates the plants through the cooperation of the water collection pipe and the drainage belt, and can also discharge excess water from the roots of the plants, thus avoiding the root rot caused by excessive water accumulation in the roots; at the same time, through the drainage belt The water in the water collection pipe is introduced into the vicinity of the roots of the plants, which can effectively avoid the waste of water resources.

(2) The present invention can ensure that the water source in the water collection pipe is sufficient by setting the irrigation water storage tank, and there will be no water shortage, which will cause the plants to lack water.

(3) Since the present invention is provided with a water flow collection pool, the water near the roots of the plants can be introduced into the water collection pipe through the drainage belt, and then flow into the water flow collection pool, which avoids the waste of water resources; at the same time, the water flow collection pool and the irrigation water storage tank Connected, the water resources collected by the water flow collection pool can be recycled, so as to realize the purpose of recycling water resources, further save water resources, and reduce irrigation costs.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

Example 1

As shown in Figure 3, a kind of system that is used for plant root system seepage irrigation and soil body drainage, comprises water collection pipe 1, and is arranged on the water collection pipe and is used for the drainage belt 2 that water imports or exports water collection pipe; Said drainage belt It is a belt-shaped member or a plate-shaped member, and at least one side thereof is provided with a groove for drainage; the drainage belt is located under the ground.

As a preference, at least one side of the drainage belt has a plurality of small-diameter collection and drainage grooves arranged at intervals along the belt width direction and extending along the entire length of the belt length direction. Narrow gaps that produce capillary action. Of course, the use of ordinary drainage belts can also realize the seepage irrigation and drainage functions of the present invention, because when the water volume in the water collection pipe reaches a certain level, the water will naturally flow out of the water collection pipe along the groove. On the contrary, when the external water volume is too much, it will also Flow into the water collecting pipe along the groove.

Irrigation and drainage of excess water near the plant roots can be achieved through the above system. The specific setting method is to bury the water collection pipe next to the plant root system, and at the same time insert one end of the drainage belt into the water collection pipe, and the other end is close to the plant root system, and then only need to inject irrigation water, nutrient solution or liquid pesticide into the water collection pipe When the liquid flows into the water collection pipe and reaches a certain degree of saturation, the liquid will be sucked into the groove due to the capillary force of the drainage belt, and then the water will be introduced into the soil with the self-flow of water and the capillary force of the soil and plant roots, so as to achieve irrigation. The role of plants.

When there is too much water near the plant root system due to rainfall or other reasons, the water near the plant root system can be sucked into the groove through the drainage belt, and then flow into the water collection pipe, so as to achieve the purpose of discharging excess water near the plant root system, thereby avoiding The waste of water resources can also prevent the root system of plants from being soaked in too much water and cause diseases such as root rot.

In addition, a water inlet valve 3 and a drainage control valve 4 are respectively provided at both ends of the water collecting pipe. By setting two valves, water inlet and outlet can be effectively controlled. In the specific operation mode, when irrigation is required, you only need to open the water inlet valve, close the drainage control valve, and then inject water into the water collection pipe. After the water in the water collection pipe reaches a certain level, the drainage belt will export the water to the Water near the roots of the plants. When it is necessary to discharge excess water near the plant root system, just close the water inlet valve, that is, stop injecting water into the water collection pipe, and then open the drainage control valve. At this time, there is too much water near the plant root system, and the water collection pipe has less water. , the drainage belt will quickly absorb the water near the plant root system into the water collection pipe and discharge it, so as to achieve the purpose of drainage.

It is worth noting that the water collection pipe of this embodiment can not only be buried in the soil above the plant root system, but also can be buried in the soil below the plant root system, and can also be on the same level as the plant root system. No matter how it is installed, as long as it is buried in the Near the plant root system, it is enough to make the drainage belt close to the plant root system. No matter how the water collection pipe is arranged, the drainage belts all play the role of exporting the water in the water collection pipe to the vicinity of the plant root system and introducing the water near the plant root system into the water collection pipe.

In addition, as shown in Figures 10 and 11, there are two kinds of drainage strips with different structures, and one or two of them can be selected for installation according to the actual situation in actual use.

Example 2

As shown in Figure 4, the difference between this embodiment and Embodiment 2 is that the present invention also includes an irrigation water reservoir 5 communicated with one end of the water collection pipe; end of the inlet valve. By setting the irrigation water storage tank, it can be realized that when irrigation is needed, only the water inlet valve can be opened for irrigation, which is very convenient, and the irrigator does not need to find another water source, which reduces the labor intensity.

Example 3

As shown in Figure 5, the difference between this embodiment and Embodiment 3 is that the present invention also includes a water flow collection pool 7 communicated with the other end of the water collection pipe; the end of the water flow collection pool connected to the water collection pipe is provided with a drainage control valve one end. By setting the water flow collection pool, the water resources discharged from the water collection pipes can be effectively recycled, further avoiding the waste of water resources.

Example 4

As shown in Figure 6, the difference between this embodiment and Embodiment 4 is that a circulating water delivery pipe 8 communicating with both of them is also provided between the irrigation water storage tank and the water flow collection pool, and on the circulating water delivery pipe Also be provided with water pump 9. By arranging the circulating water delivery pipe and the water pump, the water flow in the water flow collecting tank can be pumped into the irrigation water storage tank, so as to realize recycling and realize the recycling of water resources at the same time. Thereby greatly improving the utilization rate of water resources and saving irrigation costs.

Example 5

As shown in FIG. 7 , the difference between this embodiment and Embodiment 5 is that the water collecting pipe is further provided with a vertical ventilation pipe 12 with one end connected to it and the other end located on the ground surface. By arranging the vertical ventilation pipes on the water collection pipes, the ventilation of the soil and plant roots can be realized. The specific principle of ventilation: when the seepage irrigation is stopped, in order to make the soil and plant roots breathable, open the drainage control valve and close the water flow control valve. At this time, due to the vertical installation of the ventilation pipe on the water collection pipe, due to the physical phenomenon of pressure difference between the upper and lower layers of the soil, the external air enters the water collection pipe from the outlet end of the water collection pipe, and the grooves on the surface of the soil and the drainage belt and the water collection pipe The intercommunication forms an in-and-out channel for the external air to communicate with the soil and plant roots for convection, circulation, and ventilation, completing the ventilation function of the system.

Example 6

As shown in Figure 8, the difference between this embodiment and Embodiment 6 is that a water quality filter 10 is also provided between the irrigation water reservoir and the water pressure control adjustment pool; There is also a water flow control valve 11 between them. By installing a water quality filter and a water flow control valve, the water entering the water collection pipe can be filtered to prevent impurities from entering the water collection pipe and causing blockage. In addition, a water pressure control regulating pool 6 communicating with the irrigation water reservoir and the water inlet valve is also provided. The purpose of setting the water pressure control adjustment pool is to control the pressure of the water entering the water collecting pipe, avoiding excessive or too small pressure, so as to ensure that the water will not cause strong pressure on the water collecting pipe and the drainage belt, and prolong the service life of the present invention; Prevent excessive water from being discharged from the vertical ventilation pipe to the ground, causing waste of water resources.

Example 7

As shown in FIG. 9 , the difference between this embodiment and Embodiment 7 is that the water collecting pipe is also provided with a nutrient solution and a liquid pesticide supply storage tank 13 communicating with the water collecting pipe. By setting up nutrient solution and liquid pesticide supply storage tanks, when pesticides or other nutrient solutions need to be added, they can be directly injected into the water collection pipes through the nutrient solution and liquid pesticide supply storage tanks, without adding pesticides or other nutrient solutions to the irrigation water storage tanks. Nutrient solution, through the nutrient solution and liquid pesticide supply storage tank, can ensure that the medicinal solution can be irrigated to the root system more conveniently. Of course, in order to better achieve this effect, a valve for controlling the opening/closing of the nutrient solution, liquid pesticide supply storage tank and the water collection pipe can also be set, and the valve can be used to control the pesticide very conveniently. The injection volume of liquid can avoid the waste of liquid medicine.

It is worth noting that the present invention is not limited to the above-mentioned embodiments, and the present invention can also combine various features of the above-mentioned embodiments, such as: Embodiment 1 + irrigation water storage tank + water flow collection tank; Embodiment 1 + vertical ventilation Pipe + water pressure control adjustment pool; embodiment 2 + water flow collection pool; embodiment 1 + irrigation water storage tank + nutrient solution, liquid pesticide supply storage tank, etc.; all can achieve the effect of water-saving irrigation. The present invention will not be described in detail here.
