Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology for artificially cultivated moss, and in particular to a shallow-buried drip irrigation device for artificially cultivated moss crust formation. Background Technology

[0002] Moss crusts possess unique resilience to harsh environments. When moss crusts cover slopes, as pioneer species, they improve damaged soil conditions and form a dense crust layer to prevent wind erosion. This allows atmospheric sediments sufficient time to remain in the soil, reducing slope water erosion and becoming a key factor in restarting the restoration and succession of certain degraded ecosystems. From a biological perspective, the formation of moss crusts makes the soil surface significantly different from loose sand in terms of physical, chemical, and biological properties, giving it strong resistance to wind and water erosion. The moss crust layer is an important component of desert ecosystems, playing a crucial role in maintaining soil fertility for fixed dunes, protecting ecosystem biodiversity, improving the microenvironment, and regulating the material and water cycle. However, due to various factors such as uneven temporal and spatial distribution of water, severe water shortages significantly affect the growth and development of moss crusts, especially during the formation stage. Shallow-buried drip irrigation, as a mature agricultural water supply method, is widely used in agricultural production. Combining this water-saving water supply facility with the ecological restoration of moss crusts will greatly increase the propagation speed of moss crusts, thereby accelerating the progress of ecological restoration.

[0003] Bryophytes are less dependent on deep soil moisture and rely more on a moist surface environment to maintain normal life activities. When a large number of bryophytes need to form a crust, shallow-buried drip irrigation devices are the most water-efficient. However, because bryophytes have shorter root systems (rhizoids) than common plants, conventional drip irrigation devices deliver water to a certain depth in the soil. The water then seeps downwards under gravity and capillary action. Since bryophytes are mainly distributed on the surface of the soil or substrate, the effective water that they can actually absorb is greatly reduced. Because the water is not concentrated in the bryophyte growth area, some water resources are wasted in non-target areas, resulting in resource waste and increased irrigation costs. Moreover, excessive water flow can easily erode bryophytes that have not yet formed a crust, which is not conducive to the formation and development of the bryophyte crust.

[0004] Therefore, for the aforementioned shallow-buried drip irrigation devices, since water is not effectively concentrated in the main growth area of ​​bryophytes, some irrigation water resources seep into non-target soil layers, resulting in a decrease in water utilization rate, there is an urgent need to design a new type of shallow-buried drip irrigation device that artificially cultivates bryophyte crusts. Utility Model Content

[0005] To overcome the problem that common shallow-buried drip irrigation devices fail to effectively concentrate water in the main growth areas of bryophytes, causing some irrigation water to seep into non-target soil layers and resulting in a decrease in water use efficiency.

[0006] The technical solution of this utility model is as follows: a shallow-buried drip irrigation device for artificially cultivating moss crusts, including an installation platform; a water pump is installed on the upper part of the installation platform, the input end of the water pump is connected to a water pipe, and the end of the water pipe away from the water pump is connected to a connector for connecting to an external water source delivery pipe. The water pump provides a power source, and the output end of the water pump is connected to a main pipe for receiving water from the water pipe. The lower end of the main pipe is connected to a drip irrigation assembly, which includes a flow direction switching module, a diversion module, a drip irrigation module, and a water retention module. The flow direction switching module can control the direction of water flow, the diversion module is used to distribute the water in the main pipe to each drip irrigation module, the drip irrigation module is used to supply the water required for the moss crusts, the water retention module prevents water loss, and a reverse osmosis assembly is installed on the upper part of the drip irrigation module. The reverse osmosis assembly includes a support module and a reverse osmosis module. The support module is used to install and support the reverse osmosis module, and the reverse osmosis module conducts water to the vicinity of the plant roots.

[0007] Preferably, the mounting platform ensures the water supply equipment is stably installed on the ground. The water pump serves as the power source, drawing external water into the device through water pipes. The connector is used to achieve quick connection and sealing with the external water supply pipeline. The main pipeline receives the water flow from the water pump and delivers the water to the drip irrigation components below. The flow direction switching module can adjust the water flow direction for easy zone control or maintenance. The diversion module distributes the water in the main pipeline to multiple drip irrigation modules to achieve uniform irrigation. The drip irrigation modules slowly release water, directly supplying it to the soil. The water retention module absorbs and stores the dripped water, slowing down evaporation and loss. The reverse osmosis component guides the water upward from the soil, diffusing it to the vicinity of the roots of the bryophytes, effectively solving the problems that bryophytes have difficulty absorbing deep water due to their short root systems and that excessive water flow can easily erode the bryophytes.

[0008] Preferably, the diversion module includes two diversion pipes connected to the outer side of the main pipe, which are used to divert water from the main pipe.

[0009] Preferably, the flow direction switching module includes a three-way reversing valve installed at the connection between the main pipe and the branch pipe. The three-way reversing valve provides the function of switching the fluid flow direction, and the branch pipe ensures that the water can be evenly distributed in the soil.

[0010] Preferably, the drip irrigation module includes multiple drip irrigation pipes installed on the outer side of the distribution pipe, which supply water to the soil, and each drip irrigation pipe has a flood irrigation hole on its outer side.

[0011] Preferably, the water-retaining module includes a sponge installed on the outer side of the drip irrigation pipe, which is used to store the water dripped from the drip irrigation pipe.

[0012] Preferably, the support module includes a support rod installed on the upper end face of the drip irrigation pipe, and the support rod is provided with multiple fixing brackets.

[0013] Preferably, the reverse osmosis module includes an absorbent felt mounted on the upper end of a support rod, with multiple absorbent ropes connected to the lower end of the absorbent felt.

[0014] The beneficial effects of this utility model are:

[0015] 1. The absorbent rope uses capillary action to draw water upwards from a lower position. After rising along the absorbent rope, the water enters the absorbent mat and eventually diffuses into the surface soil where the bryophytes are located. The absorbent mat absorbs and stores the water transported by the absorbent rope, creating a continuously moist microenvironment near the roots of the bryophytes. This microenvironment serves as a substrate for the attachment, germination, and early growth of bryophyte tissue fragments and spores, slowing down the rate of water evaporation, prolonging the moist period, and thus improving water utilization efficiency.

[0016] 2. The sponge is placed close to the outside of the drip irrigation pipe. During the drip irrigation process, it absorbs and stores some of the dripped water. The sponge slowly releases the stored water, prolonging the soil moisture time, reducing water loss due to evaporation or seepage, and improving water resource utilization efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment of a shallow-buried drip irrigation device for artificially cultivating moss crusts, including an installation platform 1; a water pump 2 is installed on the upper end of the installation platform 1, the input end of the water pump 2 is connected to a water pipe 3, and the end of the water pipe 3 away from the water pump 2 is connected to a connector 4 for connecting to an external water source delivery pipe. The water pump 2 provides a power source, and the output end of the water pump 2 is connected to a main pipe 5 for receiving water from the water pipe 3. The lower end of the main pipe 5 is connected to a drip irrigation assembly, which includes a flow direction switching module, a diversion module, a drip irrigation module, and a water retention module. The flow direction switching module can control the water flow direction, the diversion module is used to distribute the water in the main pipe 5 to each drip irrigation module, the drip irrigation module is used to supply the water required by the moss crusts, the water retention module prevents water loss, and a reverse osmosis assembly is installed on the upper end of the drip irrigation module. The reverse osmosis assembly includes a support module. The system consists of a block and a reverse osmosis module. The support module is used to install and support the reverse osmosis module, which conducts water to the vicinity of plant roots. The mounting platform 1 ensures that the water supply equipment is stably installed on the ground. The water pump 2 serves as a power source, drawing external water into the device through the water pipe 3. The connector 4 is used to achieve quick connection and sealing with the external water supply pipe. The main pipe 5 receives the water flow from the water pump 2 and delivers the water to the drip irrigation components below. The flow direction switching module can adjust the water flow direction for easy zone control or maintenance. The diversion module distributes the water in the main pipe 5 to multiple drip irrigation modules to achieve uniform irrigation. The drip irrigation modules slowly release water, directly supplying it to the soil. The water retention module absorbs and stores the dripped water, slowing down evaporation and loss. The reverse osmosis component guides water upward from the soil, diffusing it to the vicinity of the roots of bryophytes, effectively solving the problem that bryophytes have difficulty absorbing deep water due to their short root systems.

[0025] Please see Figures 1-4In this embodiment, the diversion module includes two diversion pipes 6 connected to the outer side of the main pipe 5. The diversion pipes 6 are used to divert the water source in the main pipe 5 (the diversion pipes 6 are used to divert the water flow in the main pipe 5 to distribute the water more evenly to different areas, thereby improving the irrigation coverage and efficiency). The flow direction switching module includes a three-way reversing valve 8 installed at the connection between the main pipe 5 and the diversion pipes 6. The three-way reversing valve 8 provides the function of switching the fluid flow direction. The diversion pipes 6 ensure that the water can be evenly distributed to the soil (the three-way reversing valve 8 is installed at the connection between the main pipe 5 and the diversion pipes 6, and can manually or automatically adjust the water flow direction to realize the flow switching during zone control or maintenance, thereby improving the flexibility and adaptability of the device). The drip irrigation module includes multiple drip irrigation pipes 9 installed on the outer side of the diversion pipes 6. The drip irrigation pipes 9 provide water to the soil. Each drip irrigation pipe 9 has a flood irrigation hole 11 on its outer side (the drip irrigation pipes 9 and the flood irrigation holes 11 are responsible for delivering water to the soil near the plant roots, moistening the surrounding soil, reducing waste and improving water utilization through slow drip irrigation).

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, the water retention module includes a sponge 12 installed on the outer side of the drip irrigation pipe 9. The sponge 12 is used to store the water dripped from the drip irrigation pipe 9 (the sponge 12 is used to absorb and store the water released during the drip irrigation process, slow down water evaporation and loss, maintain a local soil moisture environment, and improve water use efficiency). The support module includes a support rod 7 installed on the upper end of the drip irrigation pipe 9. The support rod 7 is provided with multiple fixed frames (multiple support rods 7 form a fixed frame to support the water-absorbing felt 10, ensuring that the water-absorbing felt 10 is stably installed and effectively covers the growth area of ​​bryophytes). The reverse osmosis module includes a water-absorbing felt 10 installed on the upper end of the support rod 7. The lower end of the water-absorbing felt 10 is connected to multiple water-absorbing ropes 13 (the water-absorbing felt 10 has good water absorption and water retention performance, and is responsible for evenly spreading the water conducted by the water-absorbing ropes 13 to the vicinity of the roots of the bryophytes, creating a continuously moist growth environment. The water-absorbing ropes 13 guide the water from the lower part to the water-absorbing felt 10 through capillary action, realizing reverse water transport and supplying the surface bryophytes).

[0027] Working principle: An external water source is connected to the system through connector 4. After the water pump 2 starts, it draws water from the water pipe 3 and pressurizes the water to deliver it to the main pipe 5, providing a stable water flow to the main pipe 5. After the water flows into the main pipe 5, the three-way reversing valve 8 in the flow direction switching module adjusts the water flow direction as needed to achieve zone control. Subsequently, the water flows into the diversion pipe 6, where the diversion module evenly distributes the water to multiple drip irrigation modules. The diverted water then enters the drip irrigation pipe 9 and slowly releases water into the soil through the flood irrigation holes 11 on its outer side, achieving basic irrigation for the bryophyte area. During the drip irrigation process, some water is absorbed and stored by the sponge 12 installed on the outside of the drip irrigation pipe 9, slowing down water evaporation and deep seepage, creating a locally moist environment, and improving water use efficiency. The absorbent rope 13 installed at the upper end of the drip irrigation pipe 9 uses capillary action to pull water from the drip irrigation or soil from bottom to top and transport it to the absorbent felt 10. After absorbing the water from the absorbent rope 13, the absorbent felt 10 evenly diffuses it into the surface soil near the roots of the bryophytes, creating a continuously moist microenvironment suitable for the attachment, germination, and initial growth of bryophyte tissue fragments and spores.

[0028] Through the above steps, the absorbent rope 13 uses capillary action to transport water from a lower position to the absorbent felt 10. The absorbent felt 10 absorbs and stores the water, creating a continuously moist microenvironment at the roots of the bryophytes. This promotes the attachment of tissue fragments and spores to the topsoil and their germination, while also slowing down evaporation and improving water use efficiency. This addresses the common problem in shallow-buried drip irrigation devices where water is not effectively concentrated in the main growth area of ​​the bryophytes, causing some irrigation water to seep into non-target soil layers and resulting in decreased water use efficiency.
