As for watering the seedlings, since the mango tree is a water-loving plant, it is necessary to ensure that the soil has sufficient moisture. The existing watering method is generally mechanical spraying or manual handheld sprinkler equipment for watering. Although the mechanical spraying method can ensure the efficiency and automation of watering, its watering range is inconsistent. The seedlings in the center position are watered more, while the seedlings at the edge may be watered less. The manual sprinkler method is less efficient, so there is a need for a mango tree seedling raising and cultivation device. Summary of the invention

[0009] As an improvement of the above technical solution, the elastic member is a spring, one end of the spring is fixed to the upper end surface of the adjustment plate, and the other end of the spring is fixed to the lower end surface of the support seat.

[0010] As an improvement of the above technical solution, a through slot is provided in the middle of the adjustment plate, a drainage rod is provided through the slot, and a drainage micro hole is provided through the axis of the drainage rod.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Existing seedling raising equipment is generally various seedling raising pots, which are then placed in a greenhouse for constant temperature seedling raising. During the process, artificial lights are used to ensure that the cultivation environment has sufficient light. As for watering the seedlings, since the mango tree is a water-loving plant, it is necessary to ensure that the soil has sufficient moisture. The existing watering methods are generally mechanical spraying or manual handheld sprinkler equipment for watering. Although the mechanical spraying method can ensure the efficiency and automation of watering, its watering range is inconsistent. The seedlings in the center position are watered more, while the amount of water at the edge may be less, and the manual sprinkler method is less efficient.

[0033] In order to solve the above problems, the following embodiments are provided: Embodiment 1

[0034] See also Figures 1 to 5 , provides a mango tree seedling cultivation device, including: a support base 10 and an adjustment plate 20.

[0035] The upper end surface of the support seat 10 is provided with a plurality of centrally penetrating seedling tubes 13 and a liquid tank 14 provided on the outside of the seedling tube 13. The upper end surface of the support seat 10 is provided with an outer flow channel 15 and a central tank 16 provided at the central position. The outer flow channel 15 connects the plurality of liquid tanks 14 in sequence, and the terminal liquid tank 14 is connected with the central tank 16. A partition 132 with a permeable hole 133 provided on the surface is fixed inside the seedling tube 13. The bottom of the liquid tank 14 is provided with an inner flow channel 141 which runs through the inside of the seedling tube 13, and the inner flow channel The other end of 141 is located below the partition 132. The upper end surface of the adjusting plate 20 is fixed with a sealing plug 21 inserted into the bottom opening of the seedling tube 13 and an elastic member 22. The sealing plug 21 closes the inner flow channel 141. At least one sealing plug 21 is inserted into the central groove 16. The other end of the elastic member 22 is fixed to the lower end surface of the support seat 10. When the liquid tank 14 at the head end is filled with water, the water source overflows along the external flow channel 15 to the internal pressure adjusting plate 20 of the central groove 16 in turn to open the inner flow channel 141 and simultaneously inject water into the seedling tube 13.

[0036] First, water is injected into the liquid tank 14 at the head end. After the water source fills the liquid tank 14 at the head end, the water source will overflow. Since the outer flow channel 15 is connected to the liquid tank 14, the overflowing water source flows along the outer flow channel 15 to the inside of the next liquid tank 14. When the water source is injected into the liquid tank 14, the water source will first enter the inner flow channel 141. However, since the inner flow channel 141 enters from the side of the seedling tube 13, and the sealing plug 21 is directly inserted, the pressure of the water source inside the inner flow channel 141 acts on the side of the sealing plug 21, so it will not cause the sealing plug 21 to move. When all the liquid tanks 14 are filled, the last water source will enter the inside of the central tank 16. Since the inside of the central tank 16 is injected with water, the whole The gravity balance of the body is broken, causing the elastic member 22 to deform, thereby causing the adjusting plate 20 to move downward as a whole. At this time, the water source is filled between the sealing plug 21 and the partition 132. Since the elastic member 22 has a limit to its deformation, the injected water source will not cause the sealing plug 21 to directly detach from the interior of the seedling tube 13, so that the water source can still be locked at the bottom. Due to the capillary action of the soil, the water source in the partition 132 will be sucked into the soil. As the water source decreases and the weight decreases, the elastic member 22 will also pull up the entire adjusting plate 20, thereby ensuring that the soil can always contact the water source at the bottom. The function of the partition 132 is to prevent the water source from excessively contacting the soil, causing the root system to be in a high humidity environment for a long time, resulting in root damage.

[0037] The positional relationship between the outer flow channel 15, the liquid tank 14 and the central tank 16 is as follows: Fig. 9 As shown, the connection and circulation are carried out in a ring-shaped manner to ensure that the overflow of the water source is in a sequential state, so that after all the liquid tanks 14 are filled, the central tank 16 is the last to be filled with water.

[0038] In one embodiment, see Figure 1 and Figure 4 At least three vertically arranged shafts 11 are fixed to the lower end surface of the support seat 10, a water tank 12 is fixed in the middle of at least three shafts 11, and a water delivery component 123 extending to the liquid tank 14 located at the head end is arranged inside the water tank 12.

[0039] The water source inside the water tank 12 is input into the interior of the liquid tank 14 through the water supply component 123. In daily life, it is only necessary to ensure that the water source inside the vertical part 12 is sufficient.

[0040] To facilitate the disassembly and cleaning of the water tank, refer to Figure 1 A plurality of shaft sleeves 121 are fixed on the side of the water tank 12 , the shaft body 11 passes through the shaft sleeve 121 , and a limiting ring 122 is fixed on the outer thread of the shaft body 11 , and the limiting ring 122 is located below the shaft sleeve 121 .

[0041] The shaft body 11 is threadedly connected through a limiting ring 122, and since the water tank 12 and the shaft body 11 are penetrated by a sleeve 121, in this case, the height of the water tank 12 can be adjusted by only controlling the height of the limiting ring 122. When disassembly is required, the limiting ring 122 is directly unscrewed, and the water tank 12 can be directly disassembled from the bottom.

[0042] In one embodiment, see Figure 1 and Figure 4 The elastic member 22 is a spring, one end of the spring is fixed to the upper end surface of the adjustment plate 20 , and the other end of the spring is fixed to the lower end surface of the support seat 10 .

[0043] Since the elastic member 22 is prone to lose its elastic strength after long-term use, in order to facilitate subsequent replacement work, a spring is used to provide elastic connection and support. The spring has low cost and is convenient for replacement after long-term use.

[0044] If only welding is used for fixing, it will lead to increased difficulty in disassembly after the elasticity of the spring decreases. In order to reduce the complexity of subsequent disassembly, the two ends of the spring can be connected by hooks, that is, hooks are provided on the adjustment plate 20 and the support seat 10, and annular grooves that can be hung with the hooks are provided at both ends of the spring. In this way, the subsequent disassembly and replacement of the spring will be faster and more efficient.

[0045] In the above solution, the sealing plug 21 in the middle of the regulating plate 20 will form a cavity with the central groove 16 to store water, and this part of the water source will remain inside for a long time, resulting in the need to manually drain this part of the water source each time it is used, and it cannot be automatically recycled and reused. In order to avoid this problem, please refer to Figure 4 and Figure 5 A through slot is provided in the middle of the adjusting plate 20 , a drainage rod 23 is provided through the slot, and a drainage micro hole is provided through the axis of the drainage rod 23 .

[0046] Drainage is carried out through the drainage rod 23. Since the drainage micropores are provided inside the drainage rod 23, when the inside is filled with water, the water will leak slowly. This process is much slower than the speed at which the water inside the liquid tank 14 is injected into the seedling tube 13. Therefore, it will not affect the aforementioned water injection operation. After completing one stage of water injection and before the next stage of water injection, the water in the middle will flow out slowly until all the water is discharged before the next stage, and the discharged water will directly flow into the water tank 12 at the bottom to avoid water waste.

[0047] In the above schemes, water is poured into the bottom of the seedling tube 13, and the top of the soil is still not watered. In order to ensure the uniformity of the water source, please refer to Figure 1 , Figures 6 to 9Specifically, the inner wall of the seedling tube 13 is provided with a liquid hole 131 penetrating into the liquid tank 14, the outer side of the seedling tube 13 is provided with a liftable sealing member 241, and the surface of the sealing member 241 is provided with a liquid hole 242 connected with the liquid hole 131.

[0048] When the liquid injection in the central groove 16 is not completed, the liquid hole 131 is closed by the sealing member 241. After the central groove 16 is filled with liquid, the sealing member 241 is controlled to move until the liquid hole 131 is connected with the liquid hole 242. At this time, the water source flows into the interior of the seedling tube 13 along the liquid hole 131 and the liquid hole 242, thereby completing the water source injection in the upper layer of the soil.

[0049] In this solution, the lifting and lowering of the sealing member 241 can be achieved by a micro telescopic rod. Although this solution can meet the use requirements of the solution, it takes a long time to adjust, install and synchronize all the micro telescopic rods. In addition, it is difficult to troubleshoot when structural damage or working errors occur. In order to avoid this problem, please refer to Figures 3 to 5 Specifically, a top plate 24 is fixed to the upper end surface of the sealing plug 21 of the adjusting plate 20, and the top plate 24 is located above the supporting seat 10. The sealing member 241 is fixed to the top plate 24. When there is no water source inside the central groove 16, the height of the second liquid hole 242 is higher than the first liquid hole 131, and at this time the sealing member 241 closes the first liquid hole 131. When there is a water source inside the central groove 16, the sealing member 241 moves downward, and the first liquid hole 131 is connected to the second liquid hole 242.

[0050] The top plate 24 is directly connected to the sealing plug 21, so that when the adjusting plate 20 descends to meet the bottom water injection, the top plate 24 follows the descending. In this case, it is only necessary to ensure that the liquid hole 131 is below the liquid hole 242. When the water source needs to be injected, the liquid hole 242 descends until the liquid hole 131 is connected to the liquid hole 242. At this time, the water source injection function in the upper layer of the soil can also be completed. Since this design does not require an electric structure, it can ensure the consistency of the structural movement and ensure that the water sources injected at the top and bottom are almost the same, thereby ensuring the high controllability of the water source during the seedling cultivation process and reducing the occurrence of seedling death due to uneven water sources. Embodiment 2

[0051] In order to cooperate with the first embodiment, a method for raising seedlings of mango trees is provided, using a mango tree seedling raising and cultivating device as described in the first embodiment, including the following steps:

[0052] S10: Fill the interior of the seedling tube 13 with soil and plant the mango tree seedlings in the soil.

[0053] When filling the soil, first fill in the base soil, spread the base soil on the upper surface of the partition 132, then fill in a layer of culture soil, and finally fill in the top layer of soil, and plant the seedlings in the top layer of soil. The culture soil should not be too thick, which may easily cause the seedlings to burn. After completing the filling, water is injected.

[0054] S20: Water is injected into the liquid tank 14 at the head end. The gravity of the water source inside the central tank 16 at the end pulls out the sealing plug 21 until the inner flow channel 141 is connected with the seedling tube 13. At this time, several liquid tanks 14 simultaneously inject water into the seedling tube 13 through the inner flow channel 141 to complete the seedling planting.

[0055] The injected water source enters the central groove 16 from the liquid groove 14. The gravity of the water source entering the central groove 16 causes the gravity imbalance between the elastic member 22 and the adjusting plate 20, thereby causing the elastic member 22 to deform, causing the adjusting plate 20 to move downward. Since the sealing member 241 and the top plate 24 are connected as described above, and the top plate 24 is fixed to the sealing plug 21, in this case, when the adjusting plate 20 moves downward, not only the sealing plug 21 moves downward, but the sealing member 241 also moves downward until the liquid hole 131 is connected to the liquid hole 242, and at the same time, the inner flow channel 141 is connected to the interior of the seedling tube 13. At this time, water sources are injected into the interior at the same time above and below the partition 132. The water source above When injected into the upper layer of soil, it will be evenly dispersed in the upper layer of soil, and the soil below will serve as a backup and moisturizing agent to ensure the overall humidity of the soil. When the upper layer of water dries up, due to capillary action, the water source will enter the upper layer of soil from the lower layer of soil to ensure the humidity of the soil. In this solution, the entire sealing plug 21 moves downward due to the weight of the central water source, but when the inner flow channel 141 is opened, the inflowing water source will also give gravity to the sealing plug 21. Therefore, when the water source located below the seedling tube 13 enters the soil, the gravity on the sealing plug 21 will also decrease, so the overall gravity on the elastic member 22 will also decrease, thereby following the rise, ensuring that the water source at the bottom can always be in contact with the soil at the bottom.

[0056] To further complete the entire scheme, the following steps are also included:

[0057] S40: Place the entire device in a constant temperature greenhouse.

[0058] S50: Irradiate the interior of the seedling tube 13 through the plant growth lamp.

[0059] The constant temperature of the environment during the breeding process is ensured by a constant temperature greenhouse, and light is provided by plant growth lamps to ensure the normal growth of the seedlings inside the seedling tube 13.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
