[0052] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0053] The present application provides a seedling raising box.

[0054] First embodiment:

[0055] Please refer to Figure 2 to Figure 4 In the first embodiment of the present application, the seedling raising box comprises:

[0056] A box body 1, a front surface of the box body 1 is rotatably provided with a box door 11, and a back surface of the box body 1 is provided with a constant temperature controller 12;

[0057] A driving member 2, the driving member 2 is installed on a top of the box body 1, and a driving part of the driving member 2 is fixedly provided with a rotating pipe 21, and the rotating pipe 21 is rotatably installed in an interior of the box body 1;

[0058] A supporting mechanism 3, the supporting mechanism 3 comprises two supporting cover plates 31, two groups of trays 32, an extension plate 33 and an adjusting device 34, the two supporting cover plates 31 are symmetrically fixed on the rotating pipe 21, the two groups of trays 32 are symmetrically installed on two sides of the supporting cover plates 31, the extension plate 33 is inserted into the supporting cover plates 31 and is slidably connected, the extension plate 33 is slidably sealed with the box body 1, the extension plate 33 is one-to-one correspondingly arranged with the supporting cover plates 31, and the adjusting device 34 is installed on the rotating pipe 21 and is used for driving the extension plate 33 to be telescopically adjusted in the supporting cover plates 31;

[0059] A seedling raising tray 4, the seedling raising tray 4 is slidably installed on the tray 32, the seedling raising tray 4 is one-to-one correspondingly arranged with the tray 32, and both sides of the seedling raising tray 4 are fixedly provided with a butt joint shaft 41;

[0060] A locking frame 5, the locking frame 5 is fixedly provided on the extension plate 33;

[0061] When the extension plate 33 is contracted, the locking frame 5 locks the seedling raising tray 4 through the butt joint shaft 41; when the extension plate 33 is expanded, the locking frame 5 is separated from the butt joint shaft 41, and the seedling raising tray 4 is unlocked.

[0062] When both telescopic plates 33 are extended, the interior of the box 1 is divided into a replacement compartment 100 and a constant temperature compartment 200. The replacement compartment 100 faces the box door 11, and the constant temperature compartment 200 faces the constant temperature controller 12.

[0063] The seedling tray 4 located in the replacement chamber 100 can be replaced by opening the box door 11, while the seedling tray 4 located in the constant temperature chamber 200 can still maintain constant temperature conditions for continuous seedling cultivation, so that replacement and constant temperature do not affect each other.

[0064] In this embodiment, the thermostat 12 is connected to the inside of the enclosure 1 and has a built-in ventilation system and thermostat control system for controlling the temperature and ventilation inside the enclosure 1 (this technology is relatively mature and will not be elaborated on here).

[0065] The driving component 2 is a motor structure used to drive the rotating tube 21 to rotate and adjust. When the rotating tube 21 rotates, it synchronously drives the support cover plate 31, the tray 32 and the telescopic plate 33 to rotate as a whole, so that the seedling tray 4 can be rotated and adjusted in the box 1 after installation.

[0066] The seedling tray 4 is filled with soil and seedling seeds for seedling seed treatment in the soil, where the "soil" can be natural soil or artificial soil.

[0067] In this embodiment, the device includes two usage modes:

[0068] like Figure 4 As shown, in the rotation mode, the telescopic plate 33 is in a fully retracted state, the locking frame 5 is locked on the docking shaft 41, and the seedling tray 4 can be freely rotated and adjusted within the box 1 so that the seedling trays 4 on both sides receive uniform light and temperature distribution.

[0069] like Figure 5 As shown, in the replacement mode, the telescopic plate 33 is in a fully extended state and abuts against both sides of the inner wall of the box 1. The locking frame 5 is separated from the docking shaft 41. The seedling tray 4 in the replacement chamber 100 can be easily replaced without affecting the continuous constant temperature environment of the seedling tray 4 in the constant temperature chamber 200.

[0070] The principle of replacing the seedling tray 4:

[0071] The drive unit 2 controls the rotation of a set of seedling trays 4 that need to be replaced to face the box door 11 in advance.

[0072] The adjusting device 34 is started, the adjusting device 34 drives the telescopic plate 33 to extend, the telescopic plate 33 extends while driving the locking frame 5 to move synchronously, so that the locking frame 5 is automatically separated from the butt joint shaft 41, until the telescopic plate 33 completely abuts against the inner wall of the box body 1, so that the device is switched from the rotation mode to the replacement mode.

[0073] Then the box door 11 is opened, the seedling tray 4 to be replaced is removed and a new seedling tray 4 is replaced, and during the replacement, another group of seedling trays 4 continuously grow seedlings in the constant temperature warehouse 200 under the constant temperature state.

[0074] The telescopic plate 33 provides two use modes for the device; in the rotation mode, the driving part 2 can provide rotation adjustment support for two groups of seedling trays 4 in the box body 1, so that the two groups of seedling trays 4 can be uniformly lighted and ventilated; in the replacement mode, the telescopic plate 33 can also drive the locking frame 5 and the butt joint shaft 41 to separate synchronously during the switching from the retracted state to the extended state, so as to unlock the seedling tray 4, and facilitate the removal and replacement of the seedling tray 4; during the replacement of the seedling tray 4, the stable constant temperature seedling growing environment of the seedling tray 4 in the constant temperature warehouse 200 is maintained.

[0075] In an optional embodiment of the embodiment, the adjusting device 34 can be an electric telescopic rod. The adjusting device 34 is in one-to-one correspondence with the telescopic plate 33, and the telescopic plate 33 is controlled to extend or retract by the individual adjusting device 34.

[0076] In another optional embodiment of the embodiment, please refer to Figure 3 and Figure 4 An active sliding hole 211 is formed in the rotating pipe 21, and the active sliding hole 211 communicates the interiors of the two support cover plates 31.

[0077] The adjusting device 34 includes a first telescopic part 341, a synchronous sliding plate 342 and a first transmission rod 343, the first telescopic part 341 is fixedly connected with the rotating pipe 21 and the synchronous sliding plate 342, the first transmission rod 343 passes through the active sliding hole 211 and is hinged to the synchronous sliding plate 342 and the telescopic plate 33, and the first transmission rod 343 is in one-to-one correspondence with the telescopic plate 33.

[0078] In the embodiment, the first telescopic part 341 is an electric telescopic rod, which is used to directly drive the synchronous sliding plate 342 to ascend and descend for adjustment, and the synchronous sliding plate 342 can conveniently and simultaneously adjust the telescopic plates 33 on both sides through the two first transmission rods 343.

[0079] The synchronous adjustment principle of the two telescopic plates 33:

[0080] When it is necessary to install or replace the seedling tray 4, the first telescopic part 341 is started, which drives the synchronous sliding plate 342 to move downward, and the synchronous sliding plate 342 synchronously pushes the two telescopic plates 33 away from each other through the two first transmission rods 343, so that the two telescopic plates 33 are simultaneously switched from the retracted state to the expanded state, thereby facilitating the switching of the device from the rotating mode to the replacement mode, so as to facilitate the removal or replacement of the seedling tray 4.

[0081] Similarly, when the first telescopic part 341 drives the synchronous sliding plate 342 to move upward, the synchronous sliding plate 342 can pull the telescopic plates 33 to retract through the first transmission rods 343, so that the device is switched from the replacement mode to the rotating mode.

[0082] Conveniently, the synchronous expansion or retraction adjustment of the two telescopic plates 33 on both sides is realized synchronously under the driving action of the first telescopic part 341, so as to facilitate the synchronous switching of the use states of the two telescopic plates 33 on both sides.

[0083] Please refer to Figure 1 , the box 1 is integrally provided with temperature and humidity sensors (not shown in the figure), and the box door 11 is integrally provided with a display 13, which is signal-connected with the temperature and humidity sensors.

[0084] Conveniently, the real-time temperature and humidity in the box 1 can be collected and displayed.

[0085] Please refer to Figure 1 , the box door 11 is provided with a transparent window structure.

[0086] The transparent window structure can facilitate the entry of external light into the box 1, reduce the need for light supplement, and facilitate the intuitive observation of the seedling state in the seedling tray 4 in the box 11 without opening the box door 11.

[0087] Please refer to Figure 4 , the seedling box further comprises two groups of light supplement lamp groups 6, which are symmetrically installed inside the box 1.

[0088] The auxiliary light supplement can facilitate the supplement of the light duration under insufficient light source.

[0089] Preferably, each group of the tray 32 is provided with four, and the four trays 32 are uniformly distributed on one side of the support cover plate 31.

[0090] Increase the installable quantity of the seedling raising tray 4, so as to facilitate the simultaneous installation and constant temperature seedling raising of multiple groups of the seedling raising tray 4.

[0091] The working principle of the seedling raising box provided by the embodiment is as follows:

[0092] A1, when it is necessary to replace the seedling raising tray 4 on one side, the driving member 2 is started in advance, the driving member 2 drives the rotating pipe 21 to rotate, the rotating pipe 21 drives the support cover plate 31 to rotate, the support cover plate 31 drives the tray 32, the seedling raising tray 4, the telescopic plate 33 and the adjusting device 34 to rotate as a whole, until the seedling raising tray 4 is completely aligned to the opening direction of the box door 11, and the telescopic plates 33 on both sides are towards the two sides of the inner wall of the box body 1;

[0093] A2, the first telescopic member 341 is started, the first telescopic member 341 drives the synchronous sliding plate 342 to move downwards, the synchronous sliding plate 342 synchronously drives the two telescopic plates 33 to move away from each other through the two first transmission rods 343, and the telescopic plates 33 are synchronously driven to move away from the locking frame 5 and the butt joint shaft 41 when the telescopic plates 33 move, so that the telescopic plates 33 are switched from the retracted state to the expanded state, and the telescopic plates 33 are completely abutted on the box body 1, forming the replacement warehouse 100 and the constant temperature warehouse 200 which are isolated from each other;

[0094] A3, the box door 11 is opened, the seedling raising tray 4 in the replacement warehouse 100 is removed and replaced, and during the replacement, the constant temperature seedling raising of the seedling raising tray 4 in the constant temperature warehouse 200 is not affected;

[0095] A4, after the replacement is completed, the box door 11 is closed, and the telescopic plates 33 are controlled to return to the retracted state by the first telescopic member 341, and the equipment is switched from the replacement mode to the rotation mode.

[0096] Second embodiment:

[0097] Please refer to Figure 6 , based on the first embodiment of the seedling raising box, the second embodiment of the seedling raising box is provided. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the separate implementation of the first embodiment.

[0098] Specifically, the second embodiment of the present application provides a seedling raising box, which differs from the first embodiment in that the seedling raising box further comprises a spraying mechanism 7, wherein the spraying mechanism 7 comprises a water pump 71, a water suction pipe 72, a water supply pipe 73 and a spray head 74, the water pump 71 is installed in the box body 1, the water suction pipe 72 is installed at the input end of the water pump 71, the water supply pipe 73 is installed at the output end of the water pump 71, and the spray head 74 is installed on the water supply pipe 73 and is inclined towards the rotating range of the seedling tray 4.

[0099] In this embodiment, the water suction pipe 72 penetrates through the box body 1 and is in communication with an external water source, and the output end of the water supply pipe 73 penetrates through the box body 1 and is inserted into the box body 1, and the water pump 71 provides power for water source extraction and supply.

[0100] In this embodiment, the installation position of the spray head 74 is distributed in a staggered manner with the installation range of the seedling tray 4, thereby maintaining the stability of the equipment operation.

[0101] When the seedling tray 4 needs to be replenished with water, the water pump 71 is started, the water pump 71 draws the external water source into the water supply pipe 73 through the water suction pipe 72, and the water source is uniformly sprayed to the rotating range of the seedling tray 4 through the inclined spray head 74, thereby facilitating the provision of spray water replenishment support for the seedling tray 4 according to the use requirements.

[0102] Further, the spray head 74 is arranged in one-to-one correspondence with the seedling tray 4.

[0103] Specifically, the spray head 74 adopts an atomizing spray head, which has a wide and more uniform spraying range.

[0104] One spray head 74 is arranged in one-to-one correspondence with the seedling tray 4 on the same horizontal plane, thereby ensuring that each layer of the seedling tray 4 can be quickly and efficiently replenished with water through the corresponding spray head 74 during the rotation adjustment process.

[0105] The working principle of the seedling raising box provided in this embodiment is as follows:

[0106] B1, the seedling tray 4 monitors the humidity in the range of the box body 1 in real time during continuous seedling raising, so as to analyze the water content of the soil in the seedling tray 4;

[0107] B2, when the water in the seedling tray 4 needs to be replenished, the water pump 71 is started, the water pump 71 delivers the external water source into the water supply pipe 73 through the water suction pipe 72, and the water supply pipe 73 uniformly sprays the water source to the soil range of the seedling tray 4 through the spray head 74;

[0108] B3, during the water replenishment of the seedling tray 4, the driving member 2 is started to rotate the seedling tray 4 on both sides of the supporting cover plate 31 to realize the spray water replenishment of the seedling tray 4 on both sides under the action of a group of the spray heads 74.

[0109] Third embodiment:

[0110] Please refer to Figure 7 to Figure 8 Based on the second embodiment of the present application, the third embodiment of the present application provides another seedling box. The third embodiment is only a preferred mode of the first embodiment, and the implementation of the third embodiment does not affect the separate implementation of the first embodiment.

[0111] Specifically, the seedling box provided by the third embodiment of the present application is different in that an adjusting hole 101 is formed on the box body 1, and a locking hole 111 is formed on the box door 11.

[0112] The seedling box further comprises a locking mechanism 8, the locking mechanism 8 comprises a second telescopic member 81 and a locking rod 82, when the box door 11 is locked, the locking rod 82 is inserted into the range of the locking hole 111 through the adjusting hole 101, and the second telescopic member 81 is used to drive the locking rod 82 to extend and retract.

[0113] The second telescopic member 81 is convenient for controlling the extension and retraction of the locking rod 82.

[0114] When the locking rod 82 extends, the locking rod 82 is inserted into the range of the locking hole 111 through the adjusting hole 101, and is used to lock the box door 11 in the closed state, so that the box door 11 cannot be freely opened during the operation of the equipment.

[0115] When the locking rod 82 retracts, the locking rod 82 is completely retracted into the adjusting hole 101 and separated from the locking hole 111, and is used to unlock the box door 11, so as to unlock and open the box door 11, thereby facilitating the replacement of the seedling tray 4.

[0116] In this embodiment, when the telescopic plate 33 is in the retracted state, the locking of the box door 11 should be maintained to avoid opening the box door 11 during the rotation operation of the seedling tray 4.

[0117] After the telescopic plate 33 is adjusted to the extended state, the box door 11 is controlled to be unlocked and opened.

[0118] In an optional embodiment of the present embodiment, the second telescopic member 81 can be any one of an electric telescopic rod, a telescopic cylinder or a hydraulic telescopic rod, which is used to directly drive the extension and retraction of the locking rod 82, so as to facilitate the independent control of the locking or unlocking of the box door 11.

[0119] In another optional embodiment of the present embodiment, please refer to Figure 8 , the second telescopic part 81 comprises an elastic support 811, a sliding cover 812 and a second transmission rod 813, both ends of the elastic support 811 are elastically connected with the box 1 and the sliding cover 812, both ends of the second transmission rod 813 are hinged with the sliding cover 812 and the locking rod 82;

[0120] When the telescopic plate 33 is extended to abut against the sliding cover 812, the sliding cover 812 pushes the locking rod 82 to adaptively contract through the second transmission rod 813.

[0121] In the present embodiment, the elastic support 811 is a spring support pipe, which provides elastic support force for the sliding cover 812, so that when the sliding cover 812 is not in contact with the telescopic plate 33, the locking rod 82 can maintain insertion with the locking hole 111, maintaining the locking of the box door 11.

[0122] The unlocking principle of the box door 11 is as follows:

[0123] When the telescopic plate 33 is in the contracted state, the elastic support 811 pushes the sliding cover 812 to extend, the sliding cover 812 pulls the locking rod 82 to extend through the second transmission rod 813, and the locking rod 82 is inserted into the range of the locking hole 111, so as to lock the box door 11 in the closed state, and the box door 11 cannot be opened.

[0124] When the telescopic plate 33 is switched from the contracted state to the extended state, the telescopic plate 33 also pushes the sliding cover 812 to contract, and the sliding cover 812 pushes the locking rod 82 to contract through the second transmission rod 813 when it contracts, and the locking rod 82 is out of the range of the locking hole 111 when it contracts, so that the box door 11 is switched from the locked state to the unlocked state, and the automatic unlocking of the box door 11 is realized at the same time when the telescopic plate 33 is switched from the contracted state to the extended state.

[0125] Similarly, when the box door 11 maintains the closed state, the telescopic plate 33 recovers from the extended state to the contracted state, and the box door 11 is automatically locked to maintain the stability of the equipment operation.

[0126] Only when the telescopic plate 33 is adjusted to the extended state, the box door 11 can be unlocked; when the telescopic plate 33 is in the contracted state, the box door 11 cannot be unlocked and opened, preventing the equipment from being opened by mistake during operation.

[0127] In the preferred embodiment of the present embodiment, a resilient door closer is additionally arranged between the box door 11 and the box body 1, so that the box door 11 can be automatically closed in the state without any force, and the box door 11 is prevented from being in the open state when the device is not used.

[0128] The working principle of the seedling raising box provided by the present embodiment is as follows:

[0129] C1, during the switching of the telescopic plate 33 from the contracted state to the expanded state, on the one hand, the switching of the device mode is realized, and on the other hand, the locking frame 5 is separated from the docking shaft 41 to be unlocked;

[0130] C2, in combination with Figure 9 (a) to Figure 9 (b), during the expansion of the telescopic plate 33, the telescopic plate 33 first contacts the sliding cover 812, so that the sliding cover 812 is pressed to contract, the sliding cover 812 drives the locking rod 82 to contract through the second transmission rod 813, the locking rod 82 is extracted from the range of the locking hole 111 and separated, the unlocking of the box door 11 is realized, and the automatic unlocking of the box door 11 is realized when the device is switched from the rotating mode to the replacement mode;

[0131] C3, after the box door 11 is opened, the seedling tray 4 in the replacement bin 100 is replaced.

[0132] So as to realize the switching of the device working mode, the unlocking of the seedling tray 4 and the unlocking of the box door 11 synchronously under the control of the first telescopic part 341.

[0133] The present application also provides a preparation method of a lithium mica slag-based artificial soil, comprising the following steps:

[0134] S1: drying, crushing and sieving the mica slag, natural soil, fly ash, rice carbon husk and humic acid;

[0135] S2: uniformly mixing the raw materials obtained in step S1 according to the proportion;

[0136] S3: adding water to the mixture in step S2 and placing it in the seedling raising box for constant temperature culture for 30 days.

[0137] Specifically, the drying is natural air drying in a cool and ventilated place.

[0138] Specifically, the sieving removes particles with a particle size greater than 2 mm.

[0139] Specifically, after the water is added, the mixture is maintained at a moisture content of 40-60% of the maximum water holding capacity.

[0140] Preferably, the mixture is maintained at a moisture content of 50% of the maximum water holding capacity.

[0141] Specifically, the constant temperature culture is maintained at 25 DEG C in a constant temperature culture room.

[0142] Specifically, during the constant temperature culture for 30 days, the water loss due to evaporation is supplemented by weighing method at the same time every day, so that the relative stable moisture content is maintained during the whole constant temperature culture process, and periodic stirring is carried out during the period.

[0143] Preferably, the stirring is carried out once every 10 days during the culture.

[0144] In summary, the artificial soil prepared by the present application realizes the optimized combination of inorganic matter and organic matter, has uniform texture, good water holding capacity and aggregate stability; the lepidolite slag is rich in trace nutrients such as calcium, magnesium, iron and silicon, and has a promoting effect on plant growth, meanwhile, the lepidolite slag has the characteristics of uniform particle size and good water retention; the addition of natural soil makes the artificial soil inherit the parent material characteristics of natural soil and integrate the unique microbial population of local natural soil, thereby enhancing the ecological function of the soil; the addition of fly ash not only improves the water holding and water retention performance of the soil, but also effectively passivates heavy metals and kills pathogenic microorganisms, thereby ensuring the safe use of the soil; the addition of rice charcoal shell improves the porosity of the soil and reduces the bulk density of the soil, thereby providing a more relaxed environment for the growth of plant roots; the addition of humic acid provides rich organic matter for the soil and promotes the formation of aggregate structure, thereby enhancing the water and fertilizer retention capacity of the soil. Therefore, in the artificial soil of the present application, the components synergize with each other and jointly form a high-efficiency soil system supporting plant growth, thereby providing an ideal growth environment for plants and having significant ecological restoration and agricultural planting application potential.

[0145] By pretreating the lepidolite slag and mixing it with the remaining raw materials, an artificial soil with physicochemical properties close to real soil is prepared, which can not only solve the problem of large amount of lepidolite slag accumulation and reduce the pollution to the surrounding environment, but also realize the resource utilization of lepidolite slag and alleviate the tight land resources. In addition, the raw materials of the artificial soil are easy to obtain, the manufacturing process is simple, and the cost is low, which has certain environmental and economic benefits.

[0146] The manufacturing process can be adjusted according to the actual situation of the site. Considering that it is very difficult to mix the raw materials in the actual site, a lot of manpower and material resources are needed, therefore, in the actual treatment process, the raw materials can be first buried in the pit according to a certain proportion, and then mixed and stirred by using a rotary tiller.

[0147] Example 1:

[0148] A preparation method of a lepidolite slag-based artificial soil:

[0149] Step (1), take the lithium mica residue with water content of 18%, 10 kg of mica residue, 2 kg of natural soil, 4 kg of fly ash, 2 kg of rice carbon shell and 2 kg of humic acid are naturally air-dried, crushed and sieved to remove particles larger than 2 mm in size in a cool and ventilated place, and then the above raw materials are uniformly stirred and mixed;

[0150] Step (2), water is added to the mixture obtained in step (1) until it maintains a water content of 50% of the maximum water content, and is exposed to an artificial culture room for constant temperature culture at 25°C for 30 days. During the period, the water loss due to evaporation is supplemented by weighing method at the same time every day, so that a relatively stable water content is maintained during the whole constant temperature culture, and stirring is carried out every 10 days, to obtain the artificial soil;

[0151] Step (3), select corn seeds with plump particles, soak them in 1% potassium permanganate solution for 1 h, then soak them in water in the dark for 1 day, and use wet gauze to culture for 1 day. When the corn seeds sprout, the culture is completed. Plant the seeds in a flowerpot containing 1.2 kg of artificial soil, and observe and record the growth of corn.

[0152] Example 2:

[0153] The difference from example 1 is that in step (1), the raw materials are 8 kg of mica residue, 2 kg of natural soil, 4 kg of fly ash, 2 kg of rice carbon shell and 4 kg of humic acid.

[0154] Example 3:

[0155] The difference from example 1 is that in step (1), the raw materials are 6 kg of mica residue, 2 kg of natural soil, 4 kg of fly ash, 2 kg of rice carbon shell and 6 kg of humic acid.

[0156] Example 4:

[0157] The difference from example 1 is that in step (1), the raw materials are 12 kg of mica residue, 2 kg of natural soil, 3 kg of fly ash, 2 kg of rice carbon shell and 1 kg of humic acid.

[0158] Comparative example 1:

[0159] Use natural soil instead of artificial soil, and the rest of the steps are the same as step (3) of example 1.

[0160] Comparative example 2:

[0161] The difference from example 1 is that in step (1), all 4 kg of mushroom residue is mixed with other raw materials, without adding humic acid.

[0162] The physicochemical properties, biological toxicology, heavy metals, water retention, and compression and scouring resistance of Examples 1-4 and Comparative Examples 1-2 were measured, and the results of the soil performance and properties, heavy metal content measurement, and biological toxicology test of Examples 1-4 and Comparative Examples 1-2 are shown in Tables 1, 2, and 3:

[0170] As shown in Table 1, the pH range of the artificial soils prepared in Examples 1-4 is 6.2-7.6, all within the suitable range for plant growth. Pot experiments also demonstrate that the artificial soils effectively support plant growth, ensuring that the reclaimed artificial soils can be used for crop cultivation. The EC and CEC values ​​of the artificial soils are all within suitable ranges, exhibiting a long water retention time and good properties suitable for plant growth. The water-stable aggregate content of the soil is between 32.8% and 49.1%, showing a significant increase compared to lepidolite slag, reaching the level of normal natural soils. This ensures that the reclaimed artificial soils have appropriate texture, meeting the plant's requirements for a good physical environment such as aeration and permeability. The organic matter content of the artificial soils ranges from 5.95% to 18.56%, with high levels of both total phosphorus and available phosphorus, ensuring that the reclaimed artificial soils provide sufficient nutrients to support crop growth. The water-holding time of the artificial soil ranges from 23 to 34 days, ensuring that the artificial soil has the ability to maintain a certain level of moisture after reclamation, which is beneficial to crop growth. Table 2 shows that the heavy metal content of the artificial soils all meet the "Soil Environmental Quality Standard for Agricultural Land Soil Pollution Risk Control" (GB 15618-2018), indicating that they pose a low risk to agricultural product quality and safety, crop growth, or the soil ecological environment, and can be used for crop cultivation. Table 3 shows that the seed germination index in the saturated solution of the artificial soils prepared in each embodiment exceeds 100%, indicating that the artificial soils in these embodiments promote plant growth and have high bioavailability; at the same time, the potted plants grow well, with plant heights exceeding those of the natural soil (Comparative Example 2), further proving that the artificial soils prepared in each scheme have environmental and biological safety, and have a small risk impact on the environment after reclamation, and can replace normal natural soil for crop cultivation.

[0171] Comparing Examples 1-4 with Comparative Example 1, it can be seen that the physicochemical properties and nutrient content of artificial soil are similar to those of natural soil, and the plant germination index and pot height are better than those of natural soil. It can be seen that the overall performance of artificial soil is good and it has the function of promoting plant growth.

[0172] A comparison of Examples 1-4 and Comparative Example 2 shows that the bulk density of the Examples is lighter than that of the Comparative Example, and the water retention time is longer. The plant growth and seed germination are more ideal. It can be seen that using humic acid to replace mushroom residue can improve the water and fertilizer retention capacity of artificial soil and is more suitable for plant growth.

[0173] Since there are many property indicators of artificial soil, in order to achieve comprehensive comparison of various formulations, PCA analysis was performed on various indicators of the artificial soils prepared in Examples 1-4 and Comparative Example 2 of this invention. In accordance with the soil health assessment method of SMAF, soil physical health indicators, chemical health indicators, biological health indicators and nutrient health indicators were determined and scored using membership functions.

[0174] The values of all indexes are transformed into normalized scores, and then the comprehensive properties of Examples 1-4 and Comparative Example 2 are obtained. The physical, chemical, biological, and nutrient scores of Examples 1-4 and Comparative Example 2 are calculated, and the comprehensive scores are obtained by further processing, as shown in Table 4:

[0177] The physical, chemical, biological, and nutrient scores and the total scores of Examples 1-4 and Comparative Example 2 provided by the present application and the visualization results of significance analysis are shown in Figure 1 It can be seen from the figure that the physical, chemical, biological, and nutrient scores of each example are different, but all the scores are significantly higher than those of Comparative Example 2. For the soil physical health indexes, the bulk density of Example 2 is light, and the water holding time is long, so the score is higher, while the water holding time of Example 4 is shorter due to the smaller amount of humic acid added, so the physical score is lower. Example 3 has the most organic matter content, and the fertilizer retention capacity is excellent, which is more suitable for plant growth, so the chemical and biological scores are significantly higher than those of other examples. Overall, the artificial soil of each formula has good performance, and the comprehensive score of Example 3 is the highest, so Example 3 is determined as the optimal experimental scheme.

[0178] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the concept of the present application, using the content of the present application specification and drawings, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
