Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] The following combines with Figures 1 to 7 , to describe the embodiments of the present invention.

[0055] According to an embodiment of the present invention, a cascade drip irrigation water-salt regulation saline-alkali land management platform is provided, comprising: at least one first display platform 1, on which a plurality of first display units are arranged, the first display units comprising a saline-alkali land block 11, a first drip irrigation assembly 12 for drip irrigation to the saline-alkali land block 11, and a detection member 13 arranged in the saline-alkali land block 11, the detection member 13 is used to detect soil indicators of the saline-alkali land block 11; a display member 2 is arranged on one side of the first display platform 1, the display member 2 is electrically connected to the detection member 13, and is used to display the dynamic changes of the soil indicators.

[0056] By setting up multiple first display units on the first display platform 1, the first display units can display the application of drip irrigation technology, and display the changes in soil indicators of the saline-alkali land plot 11 through the display unit 2, so that practitioners can more conveniently study, visit and learn the application of drip irrigation technology in saline-alkali land management, and enhance the practitioners' understanding and application capabilities of saline-alkali land management, and provide examples for the management of saline-alkali land; multiple first display units can be set up with saline-alkali land plots 11 of different saline-alkali types, and then more intuitively compare the differences between the saline-alkali land plots 11, so as to display the management results of drip irrigation technology and provide theoretical support for the improvement of saline-alkali land in different regions.

[0057] like Figures 1 - 2 As shown, in one embodiment, three first display platforms 1 are provided, and the three first display platforms 1 are arranged in a stepped manner in the vertical direction, and the cross-sectional size of the first display platform 1 located above is smaller than the cross-sectional size of the first display platform 1 located below. Among them, the first display platform 1 of the upper layer is indented 1.5m inwards than the first display platform 1 of the lower layer. Here, inwards refers to the direction away from the visitors. By setting up three first display platforms 1, the space utilization efficiency can be improved, and differentiated drip irrigation can be performed for saline-alkali plots 11 at different heights, thereby displaying the corresponding governance results. As a convertible implementation method, two or four first display platforms 1 can also be provided, and there are no excessive restrictions here. As a convertible implementation method, it can also be that the cross-sectional sizes of the three first display platforms 1 are the same and they are arranged in a straight line in the vertical direction. As a convertible implementation method, it can also be that the first display platform 1 of the upper layer is indented 1m or 2m inwards than the first display platform 1 of the lower layer, and there are no excessive restrictions here.

[0058] In one embodiment, the length of the stepped drip irrigation water and salt regulation saline-alkali land treatment platform is 12.5 m, the width is 5.8 m, the height is 10 m, and the height of the first display platform 1 is 3 m. The size of the saline-alkali land block 11 on the bottommost first display platform 1 is 1 m * 1 m * 1 m, with a total of three rows, 10 in each row, for a total of 30; the size of the saline-alkali land block 11 on the middle-layer first display platform 1 is 1 m * 1 m * 0.8 m, with a total of two rows, 10 in each row, for a total of 20; the size of the saline-alkali land block 11 on the topmost first display platform 1 is 1 m * 1 m * 0.6 m, with a total of one row, for a total of 10. As a variable implementation method, it can also be that the length of the stepped drip irrigation water and salt regulation saline-alkali land treatment platform is 12 m or 13 m, the width is 5 m or 6 m, the height is 9 m or 11 m, and the height of the first display platform 1 is 2 m or 4 m. The specific set dimensions are determined according to the actual on-site situation and are not overly restricted here. As a variable implementation method, the set dimensions and set quantities of the saline-alkali land blocks 11 on each layer of the first display platform 1 are determined according to the actual on-site situation and are not overly restricted here.

[0059] In one embodiment, the stepped drip irrigation water and salt regulation saline-alkali land treatment platform is welded by a plurality of columns and crossbeams to ensure the integrity and stability of the structure. Among them, both the columns and crossbeams are made of steel, and an anti-corrosion paint is sprayed on the surface of the steel for anti-corrosion treatment to resist the erosion of the harsh environment, thereby extending the service life of the stepped drip irrigation water and salt regulation saline-alkali land treatment platform. As a variable implementation method, the stepped drip irrigation water and salt regulation saline-alkali land treatment platform can also be connected by bolts between the columns and crossbeams to facilitate on-site installation and subsequent maintenance. As a variable implementation method, hot-dip galvanizing technology can also be applied to the surface of the steel for anti-corrosion treatment.

[0060] In one embodiment, the saline-alkali land blocks 11 are placed in planting boxes. By placing the saline-alkali land blocks 11 in planting boxes, it is convenient for transportation and environmental cleaning, and it avoids mutual influence between adjacent two saline-alkali land blocks 11. As a variable implementation method, it can also be that the first display platform 1 includes a plurality of partitions for placing different saline-alkali land blocks 11.

[0061] In one embodiment, the soil types of the saline-alkali land blocks 11 are classified by particle size, including three categories: coarse soil, medium soil, and fine soil; classified by the degree of salinity-alkalinity, including three categories: mild, moderate, and severe, specifically typical saline-alkali soil types in the southern and northern regions of Xinjiang such as pure salt soil, pure soda soil, mixed saline-alkali soil, chloride saline-alkali soil, and sulfate saline-alkali soil. By simulating and displaying typical saline-alkali soils in different regions of Xinjiang, it is possible to compare the effectiveness of various typical saline-alkali soil treatment modes, and it is more convenient to display research results for practitioners.

[0062] Such as Figure 2As shown, in one embodiment, the first drip irrigation assembly 12 includes: a first water storage member 121; a first drip irrigation member 122 disposed at the saline-alkali land 11, one end of the first drip irrigation member 122 is connected to the first water storage member 121 for drip-irrigating the crops on the saline-alkali land 11. Among them, the first water storage member 121 is a water tank; all the first water storage members 121 can independently regulate the water supply to achieve differential treatment of saline-alkali lands 11 with different saline-alkali degrees; under normal circumstances, the first water storage member 121 stores drip irrigation water to provide water for the crops, and every once in a while, fertilizers are added to the first water storage member 121 and mixed with the drip irrigation water to provide nutrients for the crops; the other end of the first drip irrigation member 122 is connected to a capillary tube, and the drip heads on the capillary tube transport the water to the roots of the crops for local irrigation. By using drip irrigation technology to supply water to the crops on the saline-alkali land 11, the supply position of the water can be accurately controlled, the leaching of soil salts and the cultivation of plant roots can be effectively carried out, the utilization efficiency of water resources can be improved, and the ecological restoration and vegetation restoration of saline-alkali land can be promoted. As an alternative implementation, it can also be that the end of the first drip irrigation member 122 is directly provided with drip heads, and the drip heads are fixed near the roots of the crops on the saline-alkali land 11.

[0063] As Figure 2 , Figures 4 - 7 shown, in one embodiment, the first water storage member 121 of the first display platform 1 located below is disposed on the first display platform 1 of the upper layer. By disposing the first water storage member 121 above the saline-alkali land 11, the drip irrigation water flows towards the saline-alkali land 11 under the action of gravitational potential energy, which can reduce the power loss caused by the long-term operation of the water pump during drip irrigation and is also convenient for studying the influence of the water flow rate on the salt migration. As an alternative implementation, it can also be that the first water storage member 121 is fixed above the saline-alkali land 11 with a support frame to achieve a height difference. As an alternative implementation, it can also be that the first water storage member 121 for supplying water to the first display platform 1 is on the same layer as the corresponding first display platform 1 or at a lower position, and a driving pump can be set in the first water storage member 121 to achieve water supply.

[0064] As Figure 3 shown, in one embodiment, the first drip irrigation assembly 12 includes: a water supply member 123, one end of which is connected to the first water storage member 121 for supplying water to the groundwater level of the saline-alkali land 11. By providing the water supply member 123 to supply water to the groundwater level of the saline-alkali land 11, the height of the groundwater level of the saline-alkali land 11 can be controlled, and then the dynamic change law of salts under different environmental conditions can be revealed. As an alternative implementation, it can also be that a blind pipe or a pipe well is provided at the groundwater level of the saline-alkali land 11 for water supply.

[0065] In one embodiment, the detection component 13 is a comprehensive soil detection sensor, which can be used to detect soil pH value, soil EC value (i.e., conductivity), soil temperature, soil humidity, soil water content and other indicators of the saline-alkali land plot 11. By setting the detection component 13, it is possible to collect some soil indicators of the saline-alkali land plot 11 to monitor the movement and change of water in real time, and then to explore the evolution law of the saline-alkali land under different environmental conditions. As an alternative implementation, the detection component 13 can also be other detection structures such as a rapid soil nutrient tester, and no more restrictions are imposed here. As an alternative implementation, the detection component 13 can also be used to detect other indicators such as soil salinity, and no more restrictions are imposed here.

[0066] As Figure 3 shown, in one embodiment, the first display unit includes: a control mechanism 14, which is used to control the water supply component 123 to supply water to the saline-alkali land plot 11 to simulate the groundwater level of the saline-alkali land plot 11. By setting the control mechanism 14, it can be used to adjust the height of the groundwater level, and then to analyze the salinization process and its evolution law of the saline-alkali land plot 11 under the action of various environmental factors, providing a scientific basis for the ecological restoration of the saline-alkali land and the optimal allocation of water resources.

[0067] As Figure 3 shown, in one embodiment, the control mechanism 14 includes: a control component, which is arranged on the water supply component 123 and is used to control the flow state of the water supply component 123; a measurement component, which is communicated with the groundwater level of the saline-alkali land plot 11 and is used to measure the groundwater level; a controller, which is electrically connected to the measurement component and the control component and is used to control the start and stop of the control component according to the groundwater level. Among them, the control component is a valve. When the groundwater level of the saline-alkali land plot 11 is relatively high, the valve is closed to stop supplying water to the saline-alkali land plot 11; when the groundwater level of the saline-alkali land plot 11 is relatively low, the valve is opened to start supplying water to the saline-alkali land plot 11. By setting the measurement component, it is possible to judge the groundwater level of the saline-alkali land plot 11, and then to control whether the water supply component 123 supplies water, which can ensure that the groundwater level is always at a relatively low height and avoid increasing the salinity of the surface layer of the saline-alkali land plot 11. As an alternative implementation, the measurement component may not be provided, but the start and stop of the control component may be adjusted manually. As an alternative implementation, the control component can also be other structures such as a plug or a piston, and no more restrictions are imposed here.

[0068] As Figure 3As shown, in one embodiment, the measurement component includes: a connecting member 141, one end of which is connected to the other end of the water supply member 123. The other end of the connecting member 141 is provided with an opening, and the opening is connected to the groundwater level of the saline-alkali land 11 through a pipeline for supplying water to the groundwater level; a measuring member 142 is disposed inside the connecting member 141, and the measuring member 142 is electrically connected to the controller for measuring the liquid level change in the connecting member 141. Among them, the measuring member 142 is a float valve. By setting the connecting member 141 to communicate with the groundwater level of the saline-alkali land 11 and arranging the measuring member 142 inside the connecting member 141, the height of the groundwater level of the saline-alkali land 11 can be accurately judged by observing the liquid level change in the connecting member 141. As an alternative embodiment, it is also possible that the water supply member 123 directly extends into the groundwater level of the saline-alkali land 11. As an alternative embodiment, the measuring member 142 can also be other measuring structures such as a liquid level sensor, and no further restrictions are made here.

[0069] As Figure 3 shown, in one embodiment, the measurement component includes a scale 143, and the scale 143 is disposed on one side of the connecting member 141. By setting the scale 143, when the measuring member 142 fails, the change in the height of the groundwater level of the saline-alkali land 11 can be observed with the naked eye, and then the state of the control member can be manually adjusted to avoid affecting the regulation of the groundwater level. As an alternative embodiment, it is also possible that the connecting member 141 is a graduated cylinder, and then there is no need to separately set the scale 143.

[0070] In one embodiment, the first display unit includes: a lighting component 15, which is disposed above the saline-alkali land 11 for providing heat to the saline-alkali land 11. By arranging the lighting component 15 above the saline-alkali land 11, it is possible to simulate sunlight irradiation, provide necessary lighting conditions for the growth of crops, and explore the influence of light intensity on soil salinization.

[0071] As Figure 3As shown, in one embodiment, the lighting assembly 15 includes: a lighting member 151; a connecting member 152 connected to the lighting member 151. The connecting member 152 is movably disposed at the bottom of the first display platform 1 on the upper layer.

Among them, the lighting member 151 is an LED lighting lamp; a slide rail is provided at the bottom of the first display platform 1 on the upper layer. A slider is provided at one end of the connecting member 152 away from the lighting member 151. The slider moves on the slide rail to adjust the relative position between the lighting member 151 and the saline-alkali land 11; through holes are formed in the slider. The connecting member 152 is a steel wire rope. One end of the steel wire rope is fixed with the lighting member 151, and the other end passes through the through hole and hangs freely. A buckle is provided at the connection between the other end of the steel wire rope and the through hole to limit the movement of the steel wire rope. By setting the position of the lighting member 151 to be adjustable, the light intensity on the saline-alkali land 11 can be adjusted, and further, the water evaporation rate on the surface layer of the saline-alkali land 11 under different lighting conditions can be simulated. As an alternative embodiment, it may also be that the lighting intensity of the lighting member 151 can be adjusted, and thus there is no need to adjust the position of the lighting member 151. As an alternative embodiment, it may also be that only the connecting member 152 is movably disposed at the bottom of the first display platform 1 on the upper layer, or only the connecting member 152 is set to be telescopic.

[0072] In one embodiment, the display member 2 is a display screen, which is disposed on one side of the first display platform 1 away from the visiting passage and is used to display the dynamic changes of indicators such as the soil pH value, soil EC value (i.e., conductivity), soil temperature, soil humidity, and soil water content collected by the soil detection comprehensive sensor; a control device is provided on one side of the first display platform 1 at the bottom layer. The control device is connected to the detection member 13 and is used to collect information and transmit it to the display member 2.

Among them, the second drip irrigation assembly 32 includes a drip arrow and a water storage bottle communicated with the drip arrow. The water storage bottle is fixed on the side wall of the second display platform 3. As an alternative embodiment, the second display unit may also include a saline-alkali land 11 or other structures to be displayed, which are not limited here too much.

[0074] As Figures 1 - 2As shown, in one embodiment, guardrails are provided on the outer sides of the first display platform 1 and the second display platform 3, and the height of the guardrails is 1 m. By providing the guardrails, the personal safety of the visitors can be ensured. As an alternative embodiment, it is also possible that the opening of the planting box in the saline-alkali land plot 11 is set at a relatively high level, and then there is no need to specifically provide guardrails. As an alternative embodiment, the height of the guardrails can also be 0.8 m or 1.2 m, and no further restrictions are imposed here.
